Disk brakes on road bikes... would you?

    On a winter trainer I would definetely.
    I think weight is going to be the major factor

    When I replace my commuter i will be going for a cyclocross with disk brakes. Better in the wet, less messing around trying to get the clearance just right. The same advantages hold true for the road, so if they become available, then I would definitely consider getting a bike with them, but I don't think it would be my primary consideration.

    Should probably be put in the images of beauty thread. If I had the money I reckon I would.

    Before I bought any system, I'd like to see some independent testing and reviews. I certainly won't be an early adopter, this isn't a case of not getting a webcam in the early version, it's a little more serious when it's to with my safety.

    Ideally I'd like to wait until they come into the pro peloton, but I don't know when or if that will happen.

    Weight vs Aero i'd say. There was an article ill try find it with the thoughts from the major players in the component market(shimano/sram/zipp etc)

    There seemed to losts of conflicting info, weather they'll be lighter or more Aero, both or neither. Several thought the lack of braking surface on the hub could make it lighter(roll faster) and more aero(as shapes could be different along the rim)

    So my guess is, they are coming and will come to 'sprinters' bikes, like the venge etc, first then as the weight is sorted will become more widely adopted by the rest of the peloton

    saw some posts about mtb'ers slicing bits of fingers off with disc rotors (if this is the case) this would be a real issue in a 200 strong race peloton (or a 50 strong on for that matter)


  • Registered Users, Registered Users 2 Posts: 1,848 ✭✭✭Andy-Pandy


    I have one of these

    I love it, im not to bothered about the weight, but i have a 50km round trip commute every day and its perfect. Ive also done Sally'sGap a few times on it not a bother. The extra weight will only make me stronger when i finally get a carbon road bike.

    I am open minded but have serious doubts for road racing use.

    I'll no doubt be an early adopter, at least for the commuter and winter training bike.

    Hi Andrew,

    Just about to pick one of the Honky Inc's up myself, about another week to go. I might burst into flames for asking this or be struck by lightening or both but does the frame have a mounting plate for a kick stand (side stand)?

    My current bike has a kick stand and I find it very useful.

    I very strongly suspect it will happen, and happen soon. Disc brakes may add a bit of weight at the moment, but this is the sort of engineering issue that will be quite quickly solved if the payoff is better performance in the wet, and faster stopping in all cases - as I think it will be. How fast you go is - in a large part - determined by how fast you can stop.

    No doubt the Pro-peleton will be the early adaptors and top-end consumer road bikes will follow quickly. I think that 2-3 years ago folks on here would have turned their noses up at electronic shifting for almost all the same arguements as above, and look how quickly Di2 etc has become 'mainstream' - and lusted after by those (me) that cannot quite afford it yet.

    Bring it on.

    Would braking be any better in the dry though? As it is I've no problem locking up the rear. The tyre's adhesion to the road surface remains the issue and discs won't change that when running 23s.

    Given that manufactuers can comfortably make bikes below 6.8kgs,
    how long before everyone is laughing at the guy with the caliper brakes in the A4 race?

    This is going to cost me a fortune.


  • Registered Users, Registered Users 2 Posts: 21,083 ✭✭✭✭Stark


    Don't think I'd want disc brakes with road bike tyres. Huge potential to lose control by braking too sharply.

    Dont forget that wheels can probably be made to be lighter, stronger and more aerodynamic due to the lack of a breaking surface.

    Pros ride whatever they're paid to ride.

    Have you ridden the electronic shifting you're "lusting after"? I have. It didn't induce lust.

    Id say they will have higher spoke counts

    Rim-mounted disc brakes on my old Buell.
    Gone the way of the gramophone now though.

    I say bring on the obsolescence. I'll happily pay 50 quid to anyone looking to offload their now "defunct" calipered Colnago C50. :pac:

    The benefits ain't black and white, but if manufacturers see it as a way to sell us more stuff, it'll happen as sure as your Blu-ray player will soon become obsolete.
    Here's a good discussion from a bunch of manufacturers, prob not impartial, but interesinng: http://www.bikerumor.com/2012/02/23/disc-brakes-are-coming-to-road-bikes-but-what-about-wheels/

    Electronic groupsets are a nice toy to have if you can afford it and if someone offered me Ultegra Di2 tomorrow, I'd leap at the chance.

    But it is not the revolution that Shimano would lead you to believe it is. It's crisp, it's sharp and the front shifting is sublime. But I would find it hard to pick between it and a well tuned mechanical groupset.


  • Registered Users, Registered Users 2 Posts: 2,216 ✭✭✭Paul Kiernan


    I would have thought that on a road bike, the wet grip of the tyre would be as big a factor as the grip of the brakes. A car pulled out in front of me recently when I was descending in the wet. It all happened so fast I can't remember exactly but the braking was going fine until the front wheel locked and started sliding out from under me. And I had an unusually wide 28c tyre (at 85psi) on the front. I can't imagine how a 23c at 130psi would have fared!

    Anyone purchasing an electronic groupset and throwing the bike behind their a$$ to queue for sandwiches at their local sportive is going to get a shock when they price a replacement derailleur. 380 quid Ultegra, and nearly 600 quid Dura ace

    :rolleyes::eek:

    For that reason, old school will do me fine for a long while yet.

    I can definitely see it, you could easily combine it with the electronic group set and with a bluetooth connection you'd have a nearly cable free bike. So no hole in the frame, no exposed cables. With the right software abs, electronic stability etc would be possible.
