The problem with you bike, is that the frame and fork need to be disk brake compatiable. if either are, you can use Avid cable activated disk brakes, but would need to change hubs. these do work with STI levers.

I have a Ventana 29er, with a White Brothers triple clamp on front. Got it in the USA from MTB Tandems. Look them up on the net, the guy to talk to is Alex Nutt. He is a great guy and is always willing to assist.
