I have had it with shitty quality and retarded design outboard bottom brackets.

Old sq taper BB's used to last years. Outboard bearings last what? 6 months maybe if you disassemble the crank assembly every ride and clean behind the seal? What **** designed this system exactly?

Having said all that, I should point out I have only used Hope, and not Shimano. I now have no Hope in Hope bottom brackets. Are the Shimano ones as bad as Hope? Seriously, those little plastic discs that Hope claim are seals are totally inadequate protection against crud.

I now realise that a bearing seized and polished a little strip on my crank spindle.. the spindle must have been spinning in the inner race, so I assume the crank will need replacing?

This bike was never ridden off road.

What kind of shit is this?

Why have things gone backwards? Why are bottom brackets so shit these days?

Are Hope bottom brackets just shit compared to Shimano?

What exactly was wrong with sq taper?

I was under the impression the Hope BBs lasted longer than Shimano...at least that was the general jist I received from this forum.

Chris King are supposed to be good, though I've only just bought one, so can't really offer an informed opinion.

is your BB shell faced correctly? i found that if it isn't it can wear the bearings out faster...

Yes, it's a stupid design - square taper is perfect for 99% of riders.

Not as stupid as press-fit BBs, though.

Have you been tightening the preload thing to tight?

On the plus side, there's no risk of them suffering from the old square taper problem of getting seized into the frame after 15 years of reliable use...

I share your pain, although I mellowed a little when I found that you could get replacements for €10 from bike-discount.de.

you have been fitting you cranks or bb wrong. too much pre-load you should get a lot lot more then 6 months out of a hope bb. do you have a torque wrench?

Just to counter the OP's unfortunate findings with Hope bottom brackets... I've had two on several bikes over several years and they've proven to be very robust and reliable. Each and every frame has had the BB faced, whether that makes a significant difference..?

4000 ish dry miles on my road bike and my ultegra bb was bobbins. None drive was OK but the drive side was shot. I doubt my MTB bb's see anywhere near that mileage but a cannock chase winter can destroy one in a few months.

Bobbins.

For me the hope ones have been faultless , the oldest is three years old and still fine
And if the bearings do fail they can be replaced on there own

Outboard bearings last what? 6 months maybe if you disassemble the crank assembly every ride and clean behind the seal?

You should probably ask yourself why your BBs are wearing out so fast when other people's don't. Overtightened? Really wonky frame? (I'm not sure if I believe in facing, but you never know) Or has it just done astronomical miles?

I use XT in most of my bikes, they last pretty well these days. No need to do any sort of servicing (which is just as well as they make it intentionally hard to do). Gusset and Hope in a couple of others. All do the job.

Did kill a Deore one completely in 6 hours though.

agree with Northwind, most people don't go through BBs that quickly. I've used precisely 2 external BBs in the last 4 years. one XT and then a Hope one which I changed from the XT because it was red, that's been on my only mountain bike for 4 years.

Hope here and an Acros ceramic. Both over 4 yrs old and been switched onto different frames.
OP must have the wrong type of crud locally.

AFAIK Hope bearings are stainless, Shimano are steel so the Hopes should last a lot longer. I get at least 18 months out of Hopes even riding through the winter porridge.

IMO no MTB sold in the UK should have ANY non stainless bearings.

PS: you aren't jet washing them are you?......

Killed my raceface one in 6 months, replaced it with an XT 23 months ago, which is still going strong. My other bike has had an SLX in for 12 months and is fine. I ride in all conditions and do a fair wack of miles.

I've never had the frames faced but I also don't over pre-load... hmmm....

😆 Shimano are stainless too, and as it happens, Hope's are also Steel. The words Stainless and Steel are pretty much go hand in hand when it comes to bearings. (The difference is that hope also supply ones with Ceramic type bearings)

No, bearing steel is generally not stainless as it's harder. Depends how you expect the bearing to fail as to what you'd pick.

wearing out/solid ingress - bearing steel
water ingress - plastic (e.g. blocks on sailing boats)
water ingress and wearing out - stainless (obviously less resistant to either than other options)
all of the above - ceramic

As for the OP, I used to get <1year out of UN72's, get about the same from outboard bearings, considdering UN72's were £25+ 10 years ago, add on inflation that's hope stainless bearing prices, XTR BB's are £15 from Rose, 1/3rd of the price.

Face the Frame
Fit Correctly
Tension Correctly

3 years + on hope so far going strong.

Sq Taper might be great for some but I prefer the ease of Fit/removal of HT II and the fact I can get some nice modern cranks for them.

I had a similar issue with a frame that turned out not to be faced properly. Now it is and the hope bb that's been on it for three years has been faultless...

Had my King external BB for nearly 3 years,had no problems.XT lasted over a year.

Think your frame needs prepping and the Cranks fitting with less preload.

Can't comment on Hope but the Shimano product is p1sh. 3 months from Deore, a little longer from XT. Then the play develops....

No, I'm not over tightening the preload. Yes, my frame has been faced properly(not that this makes a damn bit of difference in my view - surely the key issue here is whether the threads have been tapped parallel with each other and or their angle is on the p1ss relative to the BB shell / frame itself?)

Oh, that's riding 10hrs a week, every week, 'Scottish' conditions.

I used to go through the RF BB's in about 6 weeks. I bought a Superstar ceramic unit & that lasted even less time & with a seized bearing that scored the axle on the cranks. Had slightly better luck with a Hope ceramic, but it didn't last massively long. I now run Chris King & they just run & run. Lubed them recently, which is ridiculously easy, especially on my RF cranks with self-extractor.
One bonus of the CK design is the plastic sleeve between bearing & axle. The axle that was scored would click during pedalling as it pressed against metal bearing. No issue now, as the plastic sleeve fits snugly between crank & metal of bearing. The score is only minor, so no concern about breakage.
Should add that BB shells are faced & I don't pressure wash...although the occasional trail centre pressure washing does take place.

i'm going to stick up for outboard bearings.

my old commuter had second hand deore bearings, i ran it for a year and a half (about 4000km) and they're still fine.

my new commuter has sora stuff, and that bike has done 6 months (2000km) of winter commuting, and the bearings are fine.

when they do eventually wear out, they'll be cheap and easy to replace.

any step away from tapered axles, and crank-extractors is a good step in my opinion...

So, some people feel my pain, and some muppets claim I didn't preload properly or some such.. lol muppets.

I have two bikes with Hope BB's. I love Hope. British. Great. Not so sure about the sealing on the bottom brackets, but like I said, I haven't used outboard bearings by anyone else. Are they all shit?

Some of you guys only ride weekends, if that. See I can make assumptions too.

The bike in question never went off road, it did however do best part of 200 miles per month. The bearings lasted 4 months first time, and the latest set - Enduro replacements - lasted about the same. If I was going off road I can now see that it would be necessary to take crank off and clean behind those plastic discs every single ride. Whether to the shops or something more epic. That disc isn't adequate.

The fact is, that silly plastic disc isn't much of a seal. I wouldn't mind if I was just replacing bearings, though it pisses me off to have to keep removing cups from the BB shell, but wiping out my crank as well? What kind of planned obsolescent shit bag nonsense is this?

Yes, preload was fine. Yes, all had been faced. No, I didn't aim a jet washer inside, no I am not 10. A plastic disc is not an adequate seal. The bearing is vulnerable.

Now I have to spend money I don't have...

And my enjoyment of cycling after 30 years of being bike mad is beginning to wane.. I don't want to deal with these life-cycles any more. 9 speed stuff vanishing.. what will it be next? 11 speed? 12? 13? Paying a premium for replacements cos it is now old hat i.e. a couple of years old?

Cycling is ****ed up. Like Hope's BB sealing. Like outboard bearing design generally. All a **** up. A **** up where no **** up existed before. Well done cycling industry. Slow hand clap.

my shimano on the commuter is still smooth after a winter of misuse. had it since october and done 2500kms on it.

the hope on my race bike is as new - its done 3 strathpuffer , 1 a solo effort , many 10 unders solo and team and more recently geared day rides

the hope on my Normal SS bike has been rebuilt recently after 3 years. even then it was only a little rough , not siezed. this bike sees all the shit and gets little to no maintainance

+1 for GXP being even worse. Shockingly poor lifespan on the one that came with my Pitch.

and one more thing.. the issue IS with dirt/water finding it's way easily past the plastic disc that Hope dares call a seal.

Also, some of you guys claiming yours is still working fine with no need for maintenance.. I'd take a look inside if I was you.. mine felt fine, yet on one side the bearing wasn't spinning at all... the spindle of the crank instead spun within the race.. I have never seen such a beautifully polished inner race! Beautifully polished and black as coal!

i have - hence why i caught my SS onebefore it was gubbed

the plastic disk is a primary protector to keep the big shit out. the seal is on the bearing.

Shimano seal isnt anything different....

they are not as fit and forget as square taper but they work for me.

GXP and mega EXO are both a joke.

ISIS - lets not go there - i had 3 expensive ones on warrenty rotation on my SS for 4 years. Every 3 months id swap it out for which ever was back from the fixers.

washing with a sponge and a watering can probably helps the lifespan of mine tbh.

That plastic disc, whilst you're ranting, isn't meant to be a seal, the bearings are sealed themselves, the plastic disc is just a dust shield.

The Hope bearings are INA full stainless, which have stainless races and balls, a lot of 'stainless' brackets have stainless balls only so the race still rusts.

I have several bikes which run HT2 and all have Hope Brackets now bar the Mrs road bike. My roadbike has coming up 30,000 miles on the same bearings. The ones on the cross bikes have needed attention but they get raced in mud and filth, have the hell jetwashed out of them and then stored for a week at a time.

HT2 brackets are a bit vulnerable, but does everyone with their rose tinted specs not remember how often square taper cranks used to fall off and how much of a git it was to get a seized cup out of a frame? Don't get me started on GXP and BB30 bearings!

I still reckon the best system was Octolink and still have an XTR bracket and chainset on the Mrs commuter bike from around 1996/7 that does 20m a day and has never even seen so much as a regrease.

Was quite interested in the outcome of this, but once the OP starts with throwing about the 'retards' I've kinda lost it really.

If your crank is now dead just get a rs7 and taper bb
Just keep an eye on the crank bolts

So much piffle in this thread. The plastic disc is a seal. Yes, cartridge bearings have additional seals. However, the majority of bike components requiring bearings do not just rely on that sealing within the cartridge.

Anyway....

I did grease behind the plastic disc as per Hope's recommendation/video.. but I think I shall leave it dry from now on. I shall now remove my cranks every single week to clean behind the lame plastic seal.

I remember when UN72's lasted thousands of miles... and could be had for £15... progress is such that now I will have to disassemble my crank killing bottom bracket and give it a little wipe every single week. Ah.. can't stand in the way of progress!

lol lack of use and damp storage...

nothing to do with the crap sealing... lol

why did shit find it so difficult to get past say a UN72? Mission impossible really. Yet Hope's plastic disc? Not stopping much is it?

both bikes have avoided rain as much as possible and are kept inside in the warm.

I suppose ill chuck my tuppence in bbut this problem will always be around so its a matter of the same old ground 😕

One would surmise that the further apart the bearings are in relation to the axle would give it more support and prevent any uneven movement, this however doesnt seem to be the case as the bearings now appear to be under a heavier load and are wearing out far quicker than the old inboard bearing mounted square taper.

It should work but it isnt and i think that one of the possible reasons(or the only reason rather) is that the axle itself is flexing inside the BB shell and putting uneven force on the bearings each time you push forward on the crank 😕

Any of this making sense to anyone ? I'm poo at explaining things 😳

Further adds 😕
Its possible i think that the calculations for strength to diameter ratio are wrong and to replace a solid hardened steel bar with a hardened(i would think) steel tube the tube would need to be either wider or thicker.

Anyone know what the goal was in redesigning the BB ? was it to save weight, add strength or(cynical) sell another bit)

square taper axels used to snap and tapers would round with bad fitting or soft materials

ISIS had splines to give more contact area and bigger axel - smaller bearings were used to accomodate

hollowtech 2 uses the big axel and bigger bearings but houses them externally.

Square tapers used to snap? I rarely saw snappages. Now we just see bearing and crank failure pootling to the shops or going to work.

I don't even know how much wear on a spindle renders a crank unusable? Even if I buy another SLX at bikedirect.de, cos they are cheaper than all the UK places, it's still £110 I didn't need to spend.

It worries me that I have to check behind that disc every week. That's not tolerable maintenance to me, cos I grew up with square taper, where an XT UN72 unit could be had for £15 and literally go for years with no ingress to the bearing. There was a lot more than a plastic disc leading to the bearings in those units.

So.. grease behind the disc a bad idea?

I'm tempted to rig up some kind of headset lizard skin around the crank arm/bearing interface. Maybe not enough room round drive side though, I'll try and see what I can come up with.

Back to sq taper snappages and rounding off.. as long as you installed the crank right first time, properly torqued, my experience was that the crank would stay put. I did have experience with a Firex that seemed to keep needing retorquing every few weeks, but I am sure that could have been solved with loctite or superglue on the crank bolt.

I might seem I am knocking Hope about the bearing protection in their BB's, but it seems to me that things have gone tits up with BB's over the last few years.

Yeah maybe I should have gone for Chris King, they have a grease port don't they?

The only slight problem with Useing taper stuff now is getting good ones at an ok price
Un72 long discontinued and the top shimano one un55 is ok but not a patch on un72

For me I've got Royce in one bike and a Phil in another but both were a few quid when I got them years ago
Let alone now

On a slight tangent - might I suggest that the OP is a bit of a Grumpa Lumpa..?
a Stropalotagus Rex..?

I quite like HT2 in shimano or hope guise FWIW

Grumpy? Hardly. There's an issue with the outboard bearings I have. I cannot be the only person experiencing this crap.

Also amazed at that axle to bearing interface. What kind of lame fit is that anyway? Almost free running anyway. Seems badly engineered IMO.

One of my bikes is on it's second bb in 20 years. It was left in the rain, unused for 8 years on current bb and now serves as a singlespeed road bike.
The bb is smoother than a brand new xtr HT2 that I've just put on another bike.
This old bike also has basic cup and cone Deore hubs to reduce maintenance.

Modern kit is easy to install and nice and light but like most shit these days is designed to wear out nice and quickly.

There's some good kit around, it just disappears too quickly. Just cos I stayed with 9 speed it now feels like I have to really search around to carry a few spares. Madness. I like SRAM X9 shifters and rear mechs, and like their Shimano equivalents, they last forever.

But bottom brackets? Seriously what the ****?

The only non crap (superstar seized after 2 rides in the dry, replacement one collapsed on the drive side within a few more summer rides) ext BB I've had that failed prematurely was a shimano XT, an early one about 2006 or so? The drive side went within a few months from new.

Last one I fitted in about 2009, just a basic £12.50 deore and thats been spinning fine ever since, however I basically do not wash my bike anymore, only drive chain & stanchions, everything else stays manky to avoid unwanted water ingress, bikes also live in the house next to a radiator all the time.

My Deore HT2 lasted 3 rides, after which it was siezed completely on the nds. Utter utter junk. The XT replacement is still fine after 4 rides, so is clearly fantastic. Strangely, the GXP on my other bike has lasted 2 years in similar conditions despite being universally derided as junk. Bit of a bonkers system tho (assemble, torque up, curse at amount of play in cranks, disassemble, pack more grease in, reassemble, curse at amount of play in cranks, repeat until bed time).

Gotta agree with the OP though, never had any problems with square taper and really can't see the point (other than making us by stuff) of these silly new fangled BBs

OP, you sound like you understand bikes. Surely the fact that many of us have high mileage offroad Hope BB's still going strong after many years suggests that something you are doing isn't quite right? Doesn't make you a retard, but we all do something not quite right on our bikes from time to time.

My Hope ceramic has been ridden in dreadful conditions, and is still running perfectly. I've never removed the plastic cover and regreased mine. Maybe leaving sealed up and doing nothing is the ideal maintenance programme for a bb?

One thing I have learnt is that there is always a reason!

My experience of Shimano HTII BB's is this.

They were rubbish for the first year or so after launch.

They are now fine. My current one has lasted getting on for a year, being ridden 3 times a week (circa 10 hours a week) all year round.

I would put money on the OP jetwashing his bike on 11!

I prefer HTII to square taper by the way.

hmmmm user error im afraid

3+ year old ceramic hope bb, fitted on 3 different frames and still spins like new!

was a little grouchy and squeeky after 6 months constant wet/shitty/muddy/gritty peak district use last summer/winter (rolled into one from memory), but took seal out, took bearings out and cleaned.....back running to silent again

has covered at least 3000 peak off road miles mostly in terrible weather!

not sure how i could have just got 'lucky' with that, only thing i can say is about every 6 months i take it out give it a full clean and put it back in! it gets washed reguarly too and the bearings havent failed me yet in 3 years

Shimano ones last ages for me, up until a few months ago I was still using a crankset/BB I bought in about 2006/7.

don't think you need to jet wash to ruin HTII with water. Their position on the bike and design makes it very easy for water to linger and as a result the bearings rust.

I rarely wash the bike. I clean the necessary mostly i.e. chain etc. Amazed that people keep avoiding the obvious i.e. the fact that the bearing is rather exposed behind that Hope plastic disc. I notice the Shimano top hat cover extends further back so dirt can only get around one edge not two and grips the spindle better. Still, nice to see some people can see the wood for the trees.

To be quite honest I am thinking of selling both my Hope BB's and fit the Shimano ones that came with the cranks instead or buy XTR BB's from Rose.

I have noticed the fit between plastic sleeved BB bearings like Shimano and the crank spindle is much tighter. Even on an undamaged crank the fitting between a Hope inner bearing race (or similar i.e. Enduro Hope replacement) and spindle is worrisome. Should it be greased at all? Is metal to metal hardly snug almost free running fit a good idea on the BB/spindle?

I seem to have lost hope in my Hopes.

Can you fit regular bearings in the Hope and use a top hat like Shimano? Probably not.

Sniffle...

mines a fairly snug fit - you aint pushing it in by hand thats for sure , requires persuasion from a rubber hitting stick.

my shimano BB on my race bike lasted only a number of months - in comparison my hope ceramic has lasted many years - since 2009

including a number of endurance races in really shitty conditions and abused with pressure washers at said events.

my SS bike i use mostly has a hope ceramic in and gets fully abused with a rare wash provided by a road ride in the rain. its now 3 years old and has had one strip, clean and regrease due to a rough feeling drive side only a matter of weeks ago.

no grooves in any axles

my commuting shimano i talked about earlier is starting to complain this morning (i spoke too soon :() its an alfine chainset so assume deore level BB. Its lasted 6 months. Ill probably fit a hope ceramic since i can trust them through a process of testing on other bikes.

our road bikes only come out in good weather - usually use the commuters (alfined) in bad. so the ultegra BBs on them last plenty time - usually longer than the drive trains.

Maybe the seals can't deal with borderline aggression, lack of tolerance and a bad attitude. Perhaps they will do anything to escape - even destroy themselves.

If you can't be at least civil to others trying to help maybe you need to avoid contact with them...?

you can fit regular 25 mm ID bearings in Hope cups both enduro and Phil woods sell new 'Top Hats'

the problem with all the BB standards is the size of the BB shell for Square taper you end up with a weedy axle
for HT2 and BB30 you end up with tiny bearings stuck on the outside...
Truvative Howitzers are IMO the best of a bad bunch....

whats needed is a larger BBshell large angular contact bearings behind a layered set of seals...an outer dust sheild and an inner seal + proper seals from inside the shell

grease ports are of merit but are an answer to poor design sealing.....

for all that I think a properly set up HT2 is reasonably robust and I get 12 months + out of them

Chris King, currently on 4 years. You need to remove the crankset to re-grease it using the tool though.

Shimano SLX seem to last ages for me, couple of years on commuter bike that does about 4000 miles a year, rain shine or snow. Square taper lasted similar time, although i have philwood on a single speed thats been going for 5 years and looks like it will last forever. Some bad pitting on the case though. I have a UN72 from around 20 years ago that is still seized in a frame, the frame bent trying to get it out.

Commuter now runs a Hope, just because im worth it.

The top hats will fit Hope?

top hats only fit if you change the bearing.

its not really a hope BB any more then its just a pair of hope cups.

i dont run them cause they are a pretty colour i run them because their bearings last.

yes top hats will fit

as trail rat say's [its not really a hope BB any more then its just a pair of hope cups.]

+ the bearing rating will be lower as bothe the enduro and hopes have larger balls / better quality races....

I'd suggest fitting some new bearings from Enduro or hope.... repack them with Marine waterproof grease 1st (lift the seals use a stanley knife on the bearings both sides and push through grease from one side refit seal and fit bearings)

On a slight tangent - might I suggest that the OP is a bit of a Grumpa Lumpa..?
a Stropalotagus Rex..?

You're not kidding...

I've had no problems with Hope BBs, hubs or headsets. Anyone who knows the South Pennines will tell you that the gritstone geology round here soon exposes weaknesses in bearings, and I can't say I've had any problems that I wouldn't expect.

Grumpy? Hardly. There's an issue with the outboard bearings I have.

You have an issue with most things judging by previous posts...your attitude to helmet use still the same??

I think you just have to accept that BB bearings will periodically need replacing.
I've never had more than 6 months out of a Raceface external, but after a year of using Hope it is still smooth.
I also went back to a square taper UN55 on my SS, but as my 2nd one since January is now creaking(!)- I will probably revert to HT2. 🙄

Amazed that people keep avoiding the obvious i.e. the fact that the bearing is rather exposed behind that Hope plastic disc.

No one thinks this is an issue because every single other bearing on a bike uses pretty much the exact same system!

Headset, suspension pivots, wheel bearings, all of them are cartridge bearings that are sealed as part of the bearing, and an outer cover of some kind which just snugs on top of the bearing.

My XT bottom bracket has lasted two years with nothing more than greasing the crank spindle. I've taken the cranks off about four times over those two years, and it still spins smoothly. Maybe your hope did fail on you early which sucks, but if you really think HTIIs are so bad, then go back to a square taper.

So dishonest above!

Lots of people in this thread see a problem. Can't help it if you are a mechanical nonce.

Some outer covers are better than others. Few items are as exposed as the BB bearing. Hope's plastic outer isn't that good. The top hat is better - only one edge (the outer diameter of the disc) is exposed to ingress not two. I'd wager the inner diameter edge is the most vulnerable wrt Hope.

Stuff gets behind it easily. No brainer. Perhaps Hope had their Yorkshire puddings switched off when they thought it was a good idea. Perhaps they were too busy with cleaning out the pigeons and harassing sheep or working out the ker ching ker ching non-austerity on each single replacement bearing.

Pish.

Well, at least you are consistent OP!

Someone agrees with you = pleasant response.
Someone disagrees with you = you insult them...

Either you have a very different offline personality or you must be just lovely to live/work with or even just bump into! I would respond to your post detailing my experiences to date, but I would rather comment on the fact that after 30 years of cycling and obviously a greater span of life experience, you still think it acceptable to personally slate people who have different experiences...

I've had no problems with Hope BB's

I have two, the silver one is a good 5 years old and is still very smooth.

The black one is 3 years old and is the same.

Both bikes are ridden off road in all weather. Both BB's are on their second frame.

No maintenance to speak of other then giving them a wipe when the cranks are off to change a chainring or when swapping the BB to a new frame.

I wish frame bearings were as reliable and hard wearing

More people getting insulted in this thread than agreeing with you.

Seems like someone got out of bed the wrong side this year.

Getting tired of OP's incessant whining, failure to accept reason & downright rudeness, not just of people's posts, but now stereotyping the staff at Hope (I don't work for Hope & only have a Hope headset, that came with HT frame, so not a Hope fanboy either).
As the OP's argument seems to revolve around the plastic outer, not the actual bearing seal, I thought I'd add this picture
[img] ?w=350&h=350&a=7[/img]
This shows a Chris King BB, which is incredibly durable, with only a small plastic cover (which sits on the axle & as pointed out to OP long long ago in this thread, will allow him to run his original chainset without any clicking/grinding from wear to crank axle & bearing interface, as most BB's are axle to bearing, whereas CK have this small plastic sleeve).
So, if the CK BB works without huge chunks of plastic wrapped around the BB, perhaps the Hope one can too? Although I encountered a short lifespan on my Hope BB, anecdotal evidence on this thread indicates that longevity is generally good.
If the OP is really that unhappy, ditch the Hope, buy a CK & stop getting so defensive & abusive.

As I have had a spare few minutes I thought I would just trawl through replies to see what balance of views expressed. Ignoring OP's posts, I make it 35 disagree with him, 14 agree at least in part. I would suggest that means 'lots' don't see the problem.

Actually, I should make that 36

Plus 1 for good experience with Hope BB ( non-ceramic).
Its the only BB I haven't had issues with. I certainly have self-inflicted issues caused by washing and then leaving in the garage damp but the Hope BB has withstood same punishment without complaint....

this thread has taught me 1 thing, the OP is a bit of a bellend.

as far as BB's are concerned i've had no issues at all with shimano bearings with them lasting well over a year without issue, same for hope , raceface and GXP BB's are a different story though they reaqlly are terrible.
have an E thirteen crank&BB on my current bike and it also seems fine so far after 3 months of winter use.
