BB30 to BB90 Solution?
Dear All,
I have a Cannondale Slice (BB30) and a Trek Speed Concept (BB90). I have SRAM cranks with an older -but perfectly fine and in working order- crank-based Quarq power meter on my Cannondale that I would like to move to the Trek bike.
Is there any way to achieve this?
Many thanks in advance!

Non omnino gravis
I don't think the BB30 spindle is nearly long enough to go through a BB90 frame. The BB30 is for a std. 68mm shell width, only without external cups (like a BSA,) so the spindle is really short. As in the name, the BB90 shell is 90mm wide.
