First a bit of background...I recently bought a 56cm Tetra Pro frame, a 1997 model I think, and with it came a Dura-Ace BB (70x109). I also bought a Shimano Ultegra group to build the bike out.
So the problem I am having is installing the FC-6500 crankset (172.5 39/53), when I tighten the crank bolt the inner chainring of the crankset will contact the chainstay. Do I need a spacer? wider BB? different crankset?
