Bottom Bracket for trek speed concept

Hi all,


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?
