Replacing the GXP BB on Mrs Stoner’s 68mm shell TT frame and following BB instructions Im sure* it says to use the two supplied spacers on a 68mm BB shell.
But it’s obvious that if I do, as I tighten the NDS crank on to the axle that it’s loading the bearings. If I remove the spacers, and tighten the crank to it’s stop, the bearings are unloaded and there is no play – i.e. it all fits perfectly.
Do I have a GXP crank that will ONLY fit on a 68mm shell with no spacers? Is it a special crank? As it would appear there’s no way it could fit to a 73mm shell as the axle would be too short.
* the graphics are hardly definitive
