Anybody using the top hat adaptors to be used with the rear disk brakes for people not using the shift kit? if you are can you give ur review about them? Im in the process of rebuilding the bike which I have the frame coming and my front forks coming so now its time to upgrade from the v brakes to disk brakes. Want to be able to use both disk brakes in the front and rear and I read up on top hat adaptors from kingssalsandservice.com. Looks like a great idea for the non shift kit users out there!
