Hi all, new here! I made a mistake recently, I orderd myself a new Ultegra rear brake for my Raliegh Technium Singlespeed I've built up, after accidently snapping a part on the old 105 brake I had. Problem is, the new brake's reach is to short and If I use it I'm going to be rubbing my tires - no good! Is there a currently available 105 or Ultegra(or comparable) rear brake available with a longer reach or do I need to look for a used one? It only needs to be 2-3 mm longer than the standard 49 mm brake. The frame was new in the early nineties so its not to old. FWIW, I'm willing to trade my brand new Ultegra rear brake for a used 105 or Ultegra brake with a longer reach!! Thanks for your help!!
