The bike's just been sitting in the basement since it ain't going anywhere any time soon with this weather, but I've been wondering after reading a few things, is it likely that BB axle length is too short? Is the BB on this crank adjustable, and with the turn of a dial or something bring the chainrings further out? The crank is the following:
FSA OMEGA, 2-PC Carbon with CNC 7075/T6 Alloy Chainrings, 50/34T

If not, considering the dilemma, would it seem readily apparent that Felt spec'd a crank with a BB too short? If so, does anyone know if this crank comes with the option of using a longer BB?


Again, if it only had a good 1-2 mm, I think it would be fine, but as it is, the granny and big cog combo rubs the cage and the cage can't go in towards the frame any further. TIA
