It’s so they can sell floating rotors for £40 each in pretty colours, rather than plain steel for £20. Same reason they sell braided steel hoses.

Seems there’s a run on misquoting today: “Ok so why do they exist at all then?” was in relation to Vented rotors, not floating rotors. So it’s just a money making pisstake after all?!! no functional benefit just pretty colours. could have saved myself a lot of time here. ah well. next!

There are very few pro MTBers (any?) who weigh over 100kg. There are plenty of amateur MTBers who are. Amateur riders are more demanding on brakes than pros of the same weight because their more frequent braking causes greater average disc temperatures but lower peak disc temperatures and the greater pad contact time increases the amount of thermal energy entering the caliper and brake fluid.

A vented rotor can dissipate more heat – that’s straight-forward engineering, hence many cars with solid rear discs still have vented front discs to handle the greater loads.

If you’re a big rider riding down big hills then vented discs are a good idea. If you’re not then you’re unlikely to benefit from them.

thank you.

Hilarious! Can we be mates?

You seem really angry

Funny that. Could be something to do with legends like you who just pollute a thread about brakes with solid gold posts like “you ok hon x” and “you seem really angry”

Super constructive.

Got anything about vented rotors?

Apologies if my response wasn’t ‘credible’ enough for you. I’m not sure what credentials are required, but I tried to offer my own personal experience of having used the Hope Tech V2 brakes with Vented rotors – which was as follows:

Forgive me Digby, I actually mentioned your answer -and conclusion- earlier, in support of some real world experience to assist the OP. Your experience with vented discs is greater than mine at nil. So, no offence was intended. By ‘credible’ I simply meant any research, articles or consensus that may support them- or as i was alluding to- why they’re NOT used professionally in the modern era. Mate, I’m just curious after the OP mentioned them, I’m not wishing to add to the quota of STW smart arses, of which there are seemingly legion. At £90 a rotor, I’d expect a little more evidence of their efficacy than one anecdotal mention on a forum post.

U ok hon?x

OK with the OP’s question and my answers yes. It’s been pointed out that there are differences between pros and mortals who may drag their brakes-as if that’s a revelation. No one has- as far as I can tell- offered a credible answer about the OP’s query over vented discs, which is where i was going. But you got me Columbo, I was indeed being factitious about your alpine experience, in which you only mentioned your sucessful switch to floating rotors not vented ones. Any comments on the case for vented rotors to help the OP out? Be careful you don’t mention ‘pros’ though….

Ok so why do they exist at all then? Just to cater for the ‘average’ user who drags their brakes? Seems like a lot of R&D for negligible benefit as previous contributors make it out to be-all be it anecdotal. Btw I’m not sure ppl caught this but Boardin Bob would like to point out he isn’t average and demands his brakes stop him when “bombing down” alpine descents at 30mph or 30’plus’ depending on the forum post…. just so we’re clear.

Hope the op finds a solution amongst the BS

The sharp end of DH or EWS does not represent most riders.

:roll: umm yes, that was my point..

I’ll spell it out for you though: If it’s accepted that the demands on equipment-like brake discs- are greater “at the sharp end” of competition, and we see NO top DH or EWS rider employing them in their set up(s), It’s safe to assume ‘most riders’ will similarly find no benefit from vented rotors. The only contributor with Vented rotor experience in this thread so far states:”To be honest I’m not convinced that the vented offers significant improvement over standard floaters. I wouldn’t bother with them again to be honest”

so.. yep, negligible benefit for ‘most riders’ and/or competition. “Seems unnecessary” still stands.

No worries man. When googled, there’s actually a STW thread that pops up from a year ago or so (one of many!). Seem’s there’s a split in opinion as you might expect- the take away though seems to be that they don’t offer much of an advantage in real terms. I actually replaced a Hope floating rotor with a Clarks on on the front (203 floating) a couple of years ago and its been excellent- it was just over half the cost of the Hope one when i needed a repacement in a hurry. Its never let me down. They do emit a pleasing ‘ting ting’ when they cool after a long descent- makes you feel special lol

hi, I am aware of some of the issues of old regarding floating rotors. does this still ring true? (rivets coming loose etc)

also, vented rotors…. what the what now? do they make a difference7 are they a must with V4 hope downhill brakes?
ta!

never had an issue with loose rivets in 10+years use of hope floating rotors in downhill (hope MonoM4/ Tech E4 used- Tech E4 and 203mm rotors F+R currently). I’m not convinced there’s a performance difference over single piece rotors, though I admit buying them years ago on that belief- both sets ups have for me been equally powerful in my experience. The hope floating spider can on occasion be thick enough to cause rubbing with certain mounts etc but YMMV. I wouldn’t say they are a ‘must’ but they do look better-which is of course subjective.. There might be credible research to show a performance boost but I’ve not seen it. They are also more expensive to replace and heavier.

No personal experience with Vented rotors. Seems unnecessary. A cursory glance at the sharp end of DH or EWS suggests they have no value in the most demanding aspects of the sport..

I use a pair of Quecha boots i bought in Decathlon in the south of France a couple of years ago. Out of the box and straight into 8 hrs walking through the Gorge due Verdon. worked brilliantly. used in the UK with no problems. The vibram sole is great and very comfortable.

Go for the E4, you wont regret it. Also worth noting is Hope’s factory service- sent one to them a few months back as I don’t have the tools at home to strip them and after a couple of days they popped back better than new. Can’t fault them.

I still dream of the time when people of this great land were so moved by an advert for an American baked bean manufacturer, they rushed out, weeping and overcome in their hundreds of thousands, into the ungodly glow of a Woolworths and handed over money for a compact disc of Ladysmith Black Mambazo propelling an unknown collection of traditional African musicians into a spotlight they didn’t ask for.

We have always been feckless shits.

Are you wearing a kilt? if not, why not. Quick flash of the goods acts as a deterrent, in most situations-including weddings/christenings/funerals. At several paces most younger males will retreat upon clocking my vegetables as to avoid an embarrassing showdown. YMMV.

I’m also a recent Lancaster resident (but a refugee from Aberdeen originally) and I’ve also found the immediate local area a bit disappointing for MTB. There isn’t a single trail I could see that could be accessed in any reasonable manner from the town on bike unless you want to mix it with kamikaze drivers on the high roads in the NE exit of the town towards Caton etc. I would agree that if covering miles is important to you-take a road bike.

Farelton Knott is excellent although as some have pointed out, is not legal. Having said that, typically you’ll see as many bikes up there as walkers on any given day. I’ve not been challenged once in the 3 years ive ridden thee fairly regularly-walkers and fellow cyclists have all been sound. It’s what I would consider my ‘local’. Still requires a car and 20 mins to get there up the M6 for me.

Whitbarrow Scar also great but again, too far to ride to etc. From there you’re knocking on the proper Lakes and all that entails..

I’m a bit niche in my MTB tastes, as i’m more of a push up/hammer back down guy but if anyone out there is into their freeride as opposed to mega mile loops, then give me a shout. I’m mainly a solo rider but would welcome a companion anytime!

make the country great again.

ruh roh….
;)

Just want to echo the positive sentiment towards Northwind’s assessment. Nailed it imho.

McDonalds, 3.30 am Aberdeen, Union street. Avoid.

oh god. just shop the *unt.

What app should I be using to track/identify these? Love it when they come over.

Flightradar24 is good. More or less real time tracking. Not all military flights are tracked of course.

Never knew there’s a civil version of the F35…

yep. popular with footballers unsurprisingly. Balotelli has a yellow one the lad.

True, but he did also lead a campaign that included the Ed stone.

I still think the Ed Stone didn’t get enough attention as a peak Partridge-incarnate moment of wonder. Would have looked fantastic outside the door of Peartree Productions. After that and this now with Napalm Death, he is my hero.

The Aldi one I have has been great it was £25/30. Saw it at the weekend for £20. Good bargain at that price.

Is it the Air version? I know a few places have stopped servicing those.

No, its the coil with piggyback. it only has rebound adjustment and a factory set pro-pedal platform. Its nearest modern equivalent would be the Vanilla I guess.

Also thanks for the replies, don’t feel quite as guilty now.. interesting that there’s a feeling that rear shocks of a certain vintage seem to require very little work. Ignorance is bliss lol

2004 Z1’s, first service was last year ! Oil was still pretty clean too… Double seals, it’s like they were designed for being ridden off road in muddy gritty conditions………..

impressive!

a Honda Jazz did this to a warship? wow.

I raised this question a couple of weeks ago looking for ‘gorse proof’ gloves, and if anyone knew of any with decent knuckle protection. Similar **** responses that dissolved into a piss take. The AVS handguards came close for me as i happen to think they look alright however I slept on it and decided it would have been a mistake in the end. And a pricey mistake. Still looking for decent gloves..

is there storage for your tampons on the bike?

If it was white then that rules out anything military.

Would the UN not have roles that may depart from military air bases for the purposes of aid flights etc? They do operate the larger Antanov’s as previously mentioned- most of their fixed wing and rotary fleet is almost all white across the world.

sounds to me like an ideal introduction to the real world after university- work hard, get sweet FA. Tell him to stop being a pussy and look forward to the next 50 yrs. Its some shitty pub job, keep it in perspective before ringing up Strasbourg ffs.

Henry.

What would I do,
1. Close all faith schools, secular schools only from now on with a varied mix of children from all races.
2. No single race/religion ‘ghettos’ diversity is needed.
3. Discourage/ban the wearing of the burka, it’s just a control garment forced onto women.
4. Outlaw Halal slaughter, again religion has no place in the food chain.
Integration is the only way forward, and as this is the UK then races and religions have to integrate into OUR way of life not the other way round. If we could get the kids playing together from an early age this would all be cleared up in a matter of a few years.

secular education system you say? Like France? How well is that working out for them? give me a break, your rhetoric is rooted in prejudice, whilst you seek a solution however noble that is, further persecution is not the answer.

SOLVED: reformatted the SD after backing up the content. Now records as before.

Didn’t occur to me sooner to try that, after the problems 24hrs ago. Will now have to resort to telling people how slow I was riding, now that I can’t show them in HD. As you were.

turns out it was a young family of deer. case closed sarge’ *credits roll

any tips on a good degreaser and or techniques for flushing old grease out when repacking?

fair points amedias, tip of the hat to you.

My tyre choice is exactly that MY choice, it works for me, my riding style and the type of riding I’m doing, if it doesn’t work for someone else that’s fine, I probably don’t like their grips or saddle either…

Basically stop thinking about what other people think, by all means think about and try stuff out for yourself and listen to opinions but just because something is right for them doesn’t mean it’s right for you, but that’s for you to decide, not them.

Trust me, its not keeping me awake at night. It was an idle topic for a bike forum that I thought had some valid points. I don’t need to “stop” or start anything thanks, beyond my bicycle…

You illustrate my point nicely though, particularly when you say “i probably dont like their grips or saddle either” inferring in part that there’s too many variables involved to make a credible comment considering the vast differences in the entire bike AND rider technique involved. This degree of variability is kind of what prompted the questioning from me as to how someone can be so ‘certain’ or black and white on the matter.

thanks to Cheifgrooveguru there btw, this was almost precisely my instinct and intention in the beginning .

Stick to your subjective markers.
Grip: does wheel drift or (gulp!) break away under braking or cornering?
Dragginess: are you slower or more tired round a familiar piece of track?
Robustness: are you getting punctures on a track that you normally wouldn’t?

Be a little methodical and it will help your confidence.

Will do. Sound advice there i feel.

Never really saw the point of high rollers.

care to expand on that? what long term experience do you have with them?

I’d agree with your pal, but I would ask you how they worked your way rather than telling you you were “wrong”.

yeah that’s part of it. apparently “i’ll kill a HR on the back in no time, and they’re better on the front anyway” This seems to contradict my own experiences, hence the original ponderous question about how much is bullshit vs real quantifiable evidence.

Compound as much as tread determines whether it’s a front or rear tyre for me.

both are 60a, never run a softer compound.
