Lemond Zurich/Trek Madone
I just bought a Lemond Zurich (2008) carbon frame, but cannot find any specs on bottom bracket size, other than 68mm english thread. Does anyone know length? 103mm?? Been searching for specs on both Madone and Zurich and they are few and far between on BB...

Length for what? Waldo? The crankset determines the spindle length, not the frame - it is english 68 for sure as you have noted.

The Zurich came with Shimano Ultegra Octalink cranks that used a 109.5mm for doubles and a 119.5mm for triples. That said, as Operator pointed out, the crank determines BB spindle length, not the frame. The newer Madones have a BB interface that makes the old Octalink cranks useless, if your idea is to move the parts from a Zurich to a new Madone.....
