    ISIS BB and campy compatability?

    I know the ISIS 108mm BB is supposed to give the same chainline as the octalink 109mm BB with doubles and is therefore Shimano compatible.

    What about Campy...Will an ISIS type double and a ISIS 108mm BB give a chainline the same as a chorus crank and Chorus BB?

    I guess that is a round about way of asking if Shimano and Campy have the same 43.5mm chainline?

    I know ISIS isn't octalink compatible (ISIS is 10-spline, octalink is 8 spline).

    My question is whether or not I need a different spindle length for a campy drivetrain.....or do I just use the same ISIS 108mm BB meant for a double.

    LOL.....I'm going to sleep...It's 12:20am.
