Disk brakes

Why dont they use diskbrakes on road bikes?

[Jules]

one of the major reasons is that you'd have to have stronger forks with lugs on to support the callipers.

 

 

 

Another reason is that sort of stopping power isn't really necessary in road races. Although it would solve some of the hassles with carbon-specific brake pads etc.

Tell that to JLA

JLA forgot to swap his bike for a FS Cannondale (with disks) when he decided to do some impromptu extreme downhill

Because it looks like sh!t.

Contrarary to popular belief, disk brakes don't offer better "stopping power." Good calliper brakes stop a bike as quickly as good disc brakes. I agree with the notion that a beefier fork would be required.

On modern double-diamond road bicycles (technically called the Rover Safety Bike), the limiting factor in coming to a stop is not a function of the brakes but a function of overturning. You'll overturn the bike long before you lose traction on the front wheel. 

 

Disk brakes on road bikes only make sense on tandems where wheels routinely overheat and blow off the tyre. Disks can take a bit more heat without any adverse affect.

 

Disk brakes transmit torque through the spokes and hence rule out radial spoking and of course, weight a bit more than calliper brakes.

 

Disk brakes make wheels difficult to clean and road bikes with disk brakes will always look as filthy as their MTB cousins. I also agree that it looks crappy.

because they are HEAVY!
