Therapy Components disc brake adapter on carbon frame?
I've got a mid-late 90's Kestrel CS-X which I recently converted to a singlespeed. The frame only has canti/V-brake mounts and I'd like to run disc brakes. Therapy Components makes something called the Brake Therapy Disc Brake Conversion (http://www.therapycomponents.com/btmoreinfo.htm).
Does anyone have experience using this product, particularly on a full carbon frame? I'd most likely be running Avid BB7s and a DT Swiss 240S hub.
In talking with my LBS and Kestrel (who recently got bought out by the parent company of Fuji Bikes), they feel that it is a bad idea to use the adapter on a carbon frame. Kestrel says it will void the warranty, etc. However, the guy I spoke with at Therapy Components said the adapter puts no more force on the brake post mount than a regular V-brakes would...
Would I be a fool to try this out anyway?
