PowerSpline BB size

matt-h

I am in the process of building a winter bike and have a got a Truvativ Touro Chainset http://www.chainreactioncycles.com/truvativ-touro-power-spline-10-speed-chainset/rp-prod41866
that uses a PowerSpline BB.
Its for a 2010 Trek 2.1 but i have no idea which size BB to get.

Most likely to be the 68 x 108mm size. This is close to the standard 68 x 110mm size needed for most Hollowtech II BB's

Finding the manual is not that hard to do.

Double ring. then you need the 113mm to give the required 44.5mm chain line.
