    This may be a silly question but...Why are disc brakes not used on road bikes?

    My understanding is that

    1. that level of braking power isn't required. Standard caliper brakes do the job well enough and any more would just enhance ones ability to skid has no major function in either slowing or controlling a road bike.

    2. disc brakes are heavy (comparatively) and weight weenieism says 'down with that kind of thing'

    3. road bike frames and forks are not designed to withstand the kind of forces transmitted by brakes through the caliper mounts. Designing them to do so would probably mean increased frameset weights and as No.2 suggests this is a no.

    4. The UCI says no (or 'non')

    All that said if you do want a road bike of sorts the next years cyclocross bikes will be allowed to have disc brakes so they'll be quite similar to a road bike with discs.

    Yup, a weighty 28mm wide tyred exception to every rule with discs that 'perform about as well as a decent pair of calipers'.

    As for any excuse of improved wet braking - Swissstop Green brake pads. Significantly cheaper than disc brakes and as powerful as you like with no weight penalty.
