Turns out Jule is 17mm, Storm i dont know, HC 15 mm and SL2 16 mm.

Good point, but I’ve read of two people running them successfully so not too worried about that.

Found one brake Magura MT pad illustration on Amazon saying 15 mm, so maybe they’re all 15 mm?

Hayes V7 16×1.8mm 156g 30 eur (Out of production, but available)
Hope Trials Zone V2 20x?mm 146g 29 eur
Avid G2 16×1.85mm 145g 24 eur
Magura Julie ?x?mm 179g 15 eur
Magura Storm ?x2mm 140g 23 eur (larger braking zone than SL? less noise than SL)
Magura Storm HC ?x2mm 141g 23 eur (poor modulation at low speed?)
Magura Storm SL2 ?x2mm 118g 23 eur (2 reviewers compared the SL1 model favorably to Avid G2 and HS1 on Avid Juicy/Elixir brakes)

Shimano rotors are either only 160 mm (RT61 would work but 160 mm max) or 14 mm width.

Question is if the Hope Trials Zone, Hayes or Magura rotors would offer improvement over the G2. I’ve asked magura about track width!

Seems like formulas won’t work well, as they are 14 mm brake track like the HS1, G2 are 16 mm so are Hayes rotors. Some trials rotors are 20 mm.

So basically looking for 16 mm brake track rotors (or wider?).

Yeah wear seems normal, but still not ideal.

How wide is the break surface on formula discs? Anyone tried em with BB7s? Look promising!

From mtbr, added the approximate wear line I see on my rotors.

scotroutes Thanks! No hills here I’m afraid. Maybe sanding would do the track although a PITA. Which shimano rotors?

1. People age at somewhat different rates, you’re 39 and beyond your peak. Younger guys or guys around your age that haven’t biologically aged as much will have an advantage. This could also be related to your testosterone levels which you could check.

2. You aren’t doing hard enough maintenance workouts, most people react better to HIIT training that get your pulse up near your max for extended periods of (total) time. Since you were doing well before it would seem you do respond to exercise.

3. You aren’t fueling well, try to eat a ton of pasta 2 hours pre bike ride.

4. Do you have any GI issues? It could be something funky in there draining your energy.

5. Maybe you’re not loosing fitness and still doing well, but your mates are working out a bunch and gaining fitness every year.

Actually now it’s spinning a bit more freely, seems fine. Cheers

Is this the stw version of flat earthers? Evidence of 10 snapped cranks mean a design issue… shimano have only ever sold 100 sets* of cranks that 10% that fail.

*i saw it on a forum post once.

2 people in this thread reported snapped SLX. That’s 2 out of say 500-2000 people who read the thread. Not insignificant. In 97 shimano had to do a mega recall of cranks that snapped at the pedal I believe.
Also people on trials forums warn against hollowtech so that’s additional anecdotal evidence. Not really an issue though as you can get non hollowtech for less money and only 60 grams more.

I’m taking a week off the forums now..

two peope out of thousands who read your thread confirmed your bias

Thousands! I’m doubtful but you may be right. Around 25 unique users posted, according to the 1% rule 2500 users read the thread https://en.wikipedia.org/wiki/1%25_rule_(Internet_culture) but since It’s a question I think it’s probably somewhere between 500 and 2500.

They are aware you wont listen so they refrained. Plenty have tried to explain to you why its possible but so unlikely you should not worry – anymore than you do any other part of your bike snapping which can also happen. More facts wont sway you

Well I haven’t been presented with any facts, but I proved you wrong above kekeke I wouldn’t mind buying a second hand zee crank.

And this is for your commuter… Insert eye rolling and facepalm emojis.

<div id=”singl-7cb4c347c242c3b206d1284099388f2c”>I don’t really commute, more A-B and fooling around. I crank it pretty hard, but don’t do 10 ft drops either. I do bike on roads a lot so I don’t want any snap action to happen in traffic.</div>
<div id=”singl-ff1be3a6247f0cdb57bd53cb29b0db13″></div>

I googled shimano broken crank.

most of the broken ones I could see were solid.

I’m counting 10 hollow ones (the seemingly solid one is a hollow 105) and 0 solid crank arms snapped.Still looking for a say post 2010 snapped solid-deore or zee crank arm.

If you want to add something to this thread, either find the weight of FC MT500 spider only, or argue why my estimate say 4 year lifetime catastrophic failure rate is likely more than 2x lower. This is a bit like why not use chinese carbon handlebars, but just a bit.

95% of posters disagreeing agree just fine with a 1% lifetime failure rate btw. Admittedly the title is a bit flippant but I can’t change it now -Ireckon it draws the wrong crowd ;P Most people used to believe the world was flat, some still do.

Cheers and gnite! I will get back to you tomorrow with some weights hopefully!

*trembling*

It’s a heck of a lot better evidence than all the ha-ha you’re wrong because I said so nonsense I’m getting in this thread. Yeah, you can’t be arsed to write a thoughtful reply you’d rather just troll. I dare you, find one snapped non hollowtech deore or zee crank.

Hollowtech cranks are no better or no worse than pretty much everything else on your bike in both aspects.

It’s not superstition, of the people who read this post today that also own SLX cranks two had them SNAP. Also it’s known among trial riders that they can snap from reading around and hence are cautioned against (granted, I don’t ride trials). Non hollowtech ones simply don’t seem to snap at all. So SLX and XT makes no sense as their only marginally lighter (50-60g) and more expensive than non-hollowtech deore (which is known to be very stiff, don’t give me that but hollowtech is stiffer and that makes a difference crud).

We know however your reason for doing so is somewhat flawed and your 500 readers thought experiment was hilariously flawed thinking.

Since nobody has pointed out why it is straight up wrong I’m inclined to think it’s pretty close to the truth. You don’t necessarily need to get the steps right to get to a ballpark correct answer either. Ya’ll statistician internet warrior engineers should know this.

I’m advocating buying the new Shimano FC-MT500 or older Deore FC591 whichever is lighter and prettier to ur eyes and fit your narrow wides.

But I can’t find any info on the new line, I’ve emailed a couple of retailers about its spider only weight. Cheers.

Are you saying non hollow tech cranks do not snap ever?

Seems like Deore non hollow tech and Zee do not snap off ever. I’ve tried to find any mention or photo of one snapped. Guessing they bend before they snap, allegedly deore and zee have the same arm so bending seems unlikely too.

Will you be buying non hollow bars too? Seat post? Downtubes?

I buy brand name bars with a good rep, try to do the same for other components.

I assume you are neither a statistician or an engineer. There are so many flaws in your reasoning it’s hilarious!

Of course it’s flawed, it’s a rough estimate, but better than the ad hominem you gulped up. I’ve never said it’s a big risk, but I’m saying why the heck buy hollowtech if you have a stronger option available for 60 grams more? FC500 looks good also.

So just buy the Zee’s, WGAS?

Why start two threads in a day on the topic?

This thread is about the weight of the FC500 crank.

thisisnotaspoon:

Let’s say 500 people read the topic today, out of those 500 2 has snapped a hollowtech crank and bothered to reply about it – likely more. Out of those 500 200 use shimano hollowtech cranks to begin with. So 2/200 hollowtech cranks SNAP during their lifetime = around a 1% catastrophic failure rate, probably higher for me since I’m stronger and heavier than avg.

Are there plenty of people who have snapped solid deore or zee cranks? No negative reviews, no photos, people commending them for being strong. Doesn’t seem like it happens, they seem to bend before they break which is a preferable failure mode.

Is that worth saving 60 grams AND paying more? No.

It is a thing, even on this forum there are several people who have had them snap.

Why would you want to pay more and to save 60 grams to get a worse crank with a real risk of catastrophic failure as little in as little as 2 years? Don’t be a fashion victim.

Now what I want to know is if the new FC500 weighs a lot more than the old FC591, if not I’ll exchange my SLX for one :)

Might as well keep my Zee if I’m worried, as it’s non hollow and I have not read a single account of it snapping.

Or just get a non-hollowtech deore! Only 60 grams heavier than the SLX and cheaper

The new FC500 and FC600 are also not hollowtech, but they seem a tad heavier? I can’t find figures anywhere.

I just like the excellent coverage, all round functionality and aesthetics of the velo oranges, same ones I’ve got on a unrelated bike. Think it could work pretty darn well, no problem to manual with them on ehee

Production Privee Oka?
Kona Honzo?

I’m looking for something similar, only for a rigid fork up front. BTR is the dream.

No I haven’t, but I just ordered a slx crank going from zee and this gives me pause. I’m 190 lb and athletic. It’s not irrational when it happens to people after 2 years of normal use and this type of failure can be really dangerous.

N.B.N.B  Zee is not hollowtech. “The crank arms themselves are not hollow tech, so they do carry a small weight penalty compared to say SLX or XT cranks.” https://www.mtb-mag.com/en/test-shimano-zee-crank-arms/ some of the arms def don’t show signs of shoe wear.

I can’t find a SINGLE photo or report of a deore or zee crank arm (same non hollow arm) snapping.

Seeing a lot of snapped of slx cranks online makes me a bit concerned, but all of them seem to be the older model. I guess hollow cranks are more amenable to snapping where solid ones bend instead: no<span style=”font-size: 0.8rem;”> snapped zee or deore to be found.</span>

Aand I went for SLX M7000 with a 36t narrow wide chainring. Keeping it simple.

Haha! So, frame? The fenders* are Velo Oranges btw. SKS bluemels ICK, terrible, cracked in a month.

geex: make a suggestion and your dreams might also come true. I’ll add some nose manuals for u.

Used 27.5 Hope evo 2 wheels with e.g. WTB rims or whatnot. I paid 150 GBP for a PAIR of perfectly straight perfectly working ones.

Thanks! I’m a fashion victim but not enough of one to freeze my fingers off, still i’d prefer gloves, but if not possible, which pogies? Two value options incl shipping:

https://www.hotpog.co.uk/products/classic-pogies?variant=1896556527660 GBP 38

Bonus bacterian camel shot

End result, really happy. Didn’t measure stays before I cut them, but more than long enough for this bike. Should probably run a slightly narrower tire, but works very well. Used p clamps and drilled and threaded a hole in the seatstay to mount it on the rear.

I just got a 6 bit 2 to 8 mm set, Bosch cobalt for 12 pounds, figure i can supplement with the individual bits I need if any :)

Also, I guess cobalt drill bits might be a bit more versatile as they’re better for stainless or hardened steel.

@nickc no there’s are other colors of the “gold version” search for  OutDry™ Ex Gold Tech Shell

This is the version I got

It’s basically like a laminate rainjacket that breats, should outlast DWR coated options. Most traditional rainwear has an interior waterproof membrane (which doesn’t allow air flow) and a water-repellent coating (which degrades over time). OutDry is different: the exterior is a water-tight membrane with millions of microscopic perforations that let water vapour escape via a wicking membrane fused to the shell.

@ads678 Panniers ain’t that good for jumping around and general goofballery.

Velo Oranges installed and holy they look good. I look at the bluemels with utter disgust now.

2 x quicker than bluemels to install, no need to bend anything around the disc brakes even using P clamps on the rear!

2 x better horizontal stiffness = no bashing the side of the tire even though clearance is 1 mm lower.

10 x better looking, photos coming soon.

Furthermore you can adjust the curve of the fender by bending the metal so it’s a lot easier to get a perfect curve around the tire. I also noticed the Bluemels already had a crack after just 3 months, I will try to get a replacement and sell it : p

Jimmy: has a DWR coating which is no good for durability, it will basically rub off and leave it non waterproof.

I realized that most of these 2.5 shell jackets have a DWR water coating that will wear off, so laminate is what you want, I found this Colombia jacket that is coating free and from what I can tell is quite robust. More like a traditional vinyl rain jacket but breathable.
