Clamp on disk brakes?

My bike came with V brakes and no provision to mount disk brakes. Are there any aftermarket disk brakes that can be clamped onto the fork, vs. needing a hole drilled into the frame?

Front fork not that I'm aware of. Rear wheel depending on the bike there are some vendors that make adapters.

For the front, you will need to replace the fork. For the rear, you might try this: http://2btherapy.com/index.php/bikes...conversion-kit

It's not just a matter of 'bolting on' a disk front. The fork has to be designed to withstand the stresses of a disc brake. The mount is built on those which are so designed. As stated above, adapters are available for rear, but again if the frame is not designed for it......?

By the time you buy the adapters and buy the wheelset that accepts the brake rotors and buy the brakes themselves the total to upgrade will cost more than just selling your present bike and buying one with disc brakes on it already. Add to this the correct warnings above that the forks and frame in the dropout area are best when designed to accept the different sort of loads imposed by disc brakes and it's a slam dunk that it's easier and cheaper to sell the old and buy the new.

I don't know of anyone that has ever complained about V brakes being inadequite. Other than riding in muddy or frequently wet conditions they work great. So why the desire to upgrade?

For what it's worth, I change from Avid SD-7 V-Brakes to Avid BB-7 just two seasons ago. The difference is that I had provisions for disc brakes both front and rear on my bike already. The cost was $100 for the brakes and about $300 for the wheels I wanted. In your case, you would need a fork and adapter if desired for the rear. Properly set up SD-7 with cool stop pads perform almost as well as my BB7s in dry conditions. I can tell you this from my own personal experience. The reason I switched is that I ride in wet conditions and prefer the modulation and consistant performance in all conditions. If you are just looking to spend money - spend the $500 on another bike.
