My wife has a 2011 Trek Speed Concept 7 series (white, pink, black). We recently 'upgraded' her crank from the stock SRAM to a Shimano Ultegra FC-6700. In order to place the crank, I had to switch out the bearings. According to the Trek Owners Manual, the Shimano kit is #404699 (which is the BB90 series). I ordered a set of Enduro BB90 from a local bike shop. The bearings fit without difficulty, but I can't secure the non-drive side crank arm- the seals for the bearings make the distance too wide. If I remove the seals, the cranks operate with no problem. As far as I can tell, I've placed everything properly (used a press for the bearings, flush with the frame, etc). Any suggestions?
