Does anyone have any ideas about this one? I just bought myself an octolink bottom bracket, 73mm/113mm, all good until I tried to slide my XTR M952 chainset on. The splines on the axle are too wide :facepalm: Can anyone suggest an alternative or will I have to try and find a used one. Also, I need a 73mm but I,ve seen some that say 68 or 73, how does that work? It's for a 94 GT RTS if that helps. Thanks.
