I noticed that Paul's Components make an adapter that enables SRAM shifters to be mounted to a road bar by exploiting the Matchmaker system. I live in England so anything from Paul's is très expensive, and I cant help but think... isn't it just an appropriately sized clamp with a screw thread? therefore can't any 31.8mm braze on adapter for front mechs be used in the same way?
My overall aim get a 10 speed shifter onto my bullhorn bars, and I have some time trial brakes already so cant use bar end shifters. The appearance is very important to me, I don't want anything that looks messy or completely bodged which is why I don't want to have multiple bar ends or anything.
