OK, so I bought a Trek 5200 (OCLV carbon series) from a guy for $400 (YR unknown I believe it is around a 2000). frame is in great condition and after riding it a year I have decided to put all new parts on it because the Shimano 600's on it now are just not up to par. Having trouble shifting and a lot of grinding, had them tuned twice, stayed about 2 weeks of riding to and from work and then slowly started going back to the way it was.

So, I bought a Shimano Ultegra, 6700 set on Ebay ( again I am a new bee ) I get the box home and remove the old 600 brake set to see if it fits before I take it to the shop to have him put everything on. My new 6700 bolt on the Front Brakes is not long enough to reach through the fork. ( I tried both sets on front and back.) the set with the longer bolt works in the rear, but not in the front. Any one got any suggestions on how to save the $820 I just spent on the group set?
