    FSA SL-K Light cranksetinstall help.

    I just purchased a FSA SL-K Light standard double crankset with an English BB and need help with the install. I have searched, googled and even attempted to contact the manufacturer but nadda.

    The crankset came with a wave washer that installs on the none drive side. The instructions came with a blown up diagram so its easy to follow but it did not specify how much space should there be between the outer face of the BB and the inner face of the none drive crank arm.

    I does specify how much torque to use but when I try to torque it to specs, the cranks develop a slight drag. Not crazy drag but it is noticeable. Also I'm only able to slide the none drive crank arm about 2/3 of the way into the splines before it develops the drag. There is no lateral play but just seems odd.

    Once I get everything in place, should it be easy to pull everything apart for service or would I need a crank puller to take everything off.

    Thanks for the help.

    Assuming your BB is in tolerance width wise, then that drag you are seeing is probably normal. Are you familiar with how a external BB crankset from say shimano/campy/fsa SHOULD feel/spin when brand new? If the crankset drags only in certain parts of the rotation, it could also be a facing issue. If it drags 360 it may be normal amount of drag you are experiencing.

    Its a 360 drag so it not a facing issue. I was comparing the the drag to my Shimano 105 cranks and BB. Just seemed like a little more drag than my 105 that I took off. I hope its normal. There is no noise so I guess it would be normal. What about the spacing, have any idea?

    I think you have the wrong bottom bracket. I had a friend with the same problem, he had the wrong BB.

    On the FSA website they have BB to crankarm compability chart....
