Can I have your Bob Yak please I need it more than you you have a car.
I bet in 5-10 years discs will be on all touring/cx bikes
How much? Money where your mouth is, or you don't really believe that.
Buy me a pint and I might lend it to you. I still use it twice a month for shopping and hauling stuff - £20 of diesel in 3 months isn't too bad I think?
Oh, I'm at CW for the next month - I might be persuaded to let you buy me a pint one evening.
My experience is that I can stop much quicker - in any conditions - even on skinny 23mm tyres
My experience is that I can endo my caliper equipped road bike in any conditions, so I don't see how a disc brake could possibly stop me any faster.
Have those pro disc brakes for road bikes ever ridden a road bike with decent caliper brakes?
Ultegra good enough?
druidh, when's your LEJOG, I've forgotten...
I might come and throw money at you.
Ultegra good enough?
If you couldn't endo with them in any conditions there must be something else wrong.
Ok but I'm not drinking in CW it's full of bankers and the pubs are a bit crap really. Limehouse/Wapping or Greenwich for proper pubs and beer. Grapes in narrow St does a proper nice fish n chips, or there's a couple of Meantime pubs in Greenwich for tasty nutritious locally brewed beer.
Hah! you're actually coming to my town...
I may make a wee effort to see you along the way..
aracer £25 + inflation says disc brakes on all touring bikes over £400 (inflation linked) in 10 years.
You'd want discs for this really I'd say:

they exist because all my work-mates bikes are old and I end up sorting them out cos I are The Designated Bike Guy despite not much knowledge!. So I end up begging for old shimano 7speed shite on classifieds! They are there to be fixed for normal boring people pon an old bike that don't care!
Kev; I've got a bunch of old toot you can have, if you want? Only junk really but might be helpful to you.

Now there's a less than confident man....
I suspect we will see discs in pro cyclocross within 2 years; no need to change wheels when you can change bikes....

You're on <virtual handshake>
Now all I have to rely on is STW forum archives working in 10 years time. Can't believe you gave me that easy a win.
I'm hoping I'll have better things to do than hang out on here by then 😛
Next season?crikey - MemberI suspect we will see discs in pro cyclocross within 2 years

Ah - I knew there had to be some other get out.
not helpful to me but I seem to end up sorting all sorts of knackered bikes out. Cantilever shmantilever, so long as it stops! Couldn't sort one bike out just because of a bloody cantilever spring bit. but I got bits off here. It's all cool, people start getting into bikes from the basics and a bit of enthusiasm eh! 🙂 you wanna see this GT mess I'm sorting out!
Happy for you to have my personal details.
[i]Next season?[/i]
Hmmm, maybe.
Think there's a Dura-Ace electro-hydro lever being built as we speak by some inscrutable chap...

Missed this - which town?
It'll be a surprise..... 😉
cantis work fine...you dont need that great brakes for cross,if you have problems then change your set up,there nice and light and you can change wheels quickly .regarding uptake of disk in world level cross... a few germans and yanks will but not many
Bruce
MUDGUARDS - on wide rimmed touring bikes! This is why cantis are still used. Pauls components make the nicest.
It's easy to fit mudguards - really, really wide ones if you must - with disc brakes.

...Oh and what druidh said - folk who are anti-disc-brake have never used them on road bikes for any length of time.
I can't see the point for skinny tyres. Disks certainly work well, but they are heavier than cantis which also work well with skinny tyres if set up properly with good cables.
I'm using disks on my road bike, but then it's got Big Apples which at 2.35" can handle them.

and cantis on the cx bike - even though it has a disk mount on the front fork.

And your drum brakes aren't heavier?
To me the benefits of discs on road bikes are clear - they are better than caliper brakes in dry (slightly) and wet (massively) IME. You can never have too much brake, especially when commuting.
I've never managed to endo on tarmac (though I've not tried that hard, and I can't skid the front wheel either).
For road bikes certainly I think the problems with discs are the torsional force trying to twist the fork and the rotational mass of the rotor itself. Both mean that there is a weight/time penalty that is unlikely to be outweighed by a braking benefit.
The answer would be to fit tiny multi-piston calipers to both sides of the fork on very small rotors.
I'm reasonably happy with Canti brakes on my Kaffenback in terms of power, but they make the fork judder in an unpleasant way, have I just set them up wrong?
so if the advantage of Cantis over Vs is mud clearance, why did every mountain biker flock to V's when they came out? Surely mud clearance is more of an issue there than on touring bikes?

Look at what you went over, Dude!
[i]Yeah, I bunnyhopped that shit![/i]
Yeah, with your head!
😆
Come on though. When v-brakes came out, it was like a revelation. Far, far easier to set up, and far, far more powerful.
If you've got little tiny girly hands, the more powerful the brakes, the better, cos you're not squeezing so hard to slow down and stop. Vs and discs FTW. I would never ever go back to cantis, and tbh the caliper brakes on my road bike put me off riding it.
Order of efficiency is:
Discs
Vs
Cantis
Calipers.
If roadies want to carry on using crappy little caliper brakes cos they're all luddite heathens, then let 'em. I'm sure common sense will influence the market enough to see that tiny little discs appear on road bikes within the next few years. It's a Logical Progression, y'know, bit like Evolution...
PRC what are you on about?
I'd bet the legs on your average road fork have easily enough torsional stiffness to add a mount to. As for rotational mass...do you mean the force produced at the caliper? Ditto.
5lab, who are you? I'm a Crediton local.
I used to pour scorn on disks-on-the-road.
Then I started using them, and happily ate my words, never looked back.
OK you can set cantis up to work well, dual pivots with decent pads are blindingly good. But disks are just as good, plus:
1) disk pads last longer. I commute 5 days a week, and the same bike is my only transport everywhere else too. I'd go through a set of canti/dual pivot pads once a fortnight in winter, plus accelerated wear means forever winding the corroded cable stop out. All in my garage at minus 5, in the dark. I don't miss that at all. This winter I used one set of disk pads.
2) I have neither the time nor inclination to wash my bike properly two or three times a day in winter. The most it will get is the contents of my water bottle dumped over it to wash the worst off. canti/dual pivot pads meant grubbing around in the black filth left behind, plus disk brakes suffer far fewer corrosion issues and no alignment issues. Corroded bolts/pivots/fixings on V's and canti's and dual pivots are a complete PITA and there are far more of them.
3) rims last a LOT longer. I'd go through a set or two a year.
4) predictable constant lever feel, wet/dry/whatever.
5) Excellent modulation with instant bite. Took me a while to stop grabbing a fistful of back brake hoping something would happen a la rim brakes. With disks, always there, and the excelelnt lever feels means uber power with no locked wheels.
6) Spares everywhere. Pads are cheap. Cables are std. Nowt to go wrong. Very easy to work on.
7) No fork judder when laden.
8) Adequate power when heavily laden.
9) Mud, ice, slush and snow cannot collect in places and lock the wheel.
I'm sure I could think of more.
Order of efficiency is:Discs
Vs
Cantis
Calipers
That's your analysis based on your extensive knowledge of engineering, elf? 🙄
I've never managed to endo on tarmac (though I've not tried that hard, and I can't skid the front wheel either).
But the fact you could if you did try harder with standard cantis or calipers (at least I can on my bikes with those - maybe you're just mechanically inept) proves that you wouldn't stop faster with discs.
I can and have, with both discs and rim brakes, both inadvertantly and on purpose.
Its still irrelevant.

They look like road bikes to me, so more likely to be callipers, surely?

It's highly relevant given exaggerated claims about stopping faster with discs.
Only if you believe that the only point of comparison is just before the tyres lose traction. If that were the case, we'd still be running V-brakes on MTBs too as a proper set-up can also cause a tyre to skid.
I am looking forward to replacing the v brakes on my commuter with discs, mainly because of the hassle free pad replacement - I know, I'm lazy but now I am used to discs and like the re-assurance of knowing the power is there if needed.
