Not sure why I am having problems but the HollowtechII bottom bracket tool I've got only fits the drive side of my SRAM GXP bottom bracket - are the SRAM and Shimano bottom brackets subtly different?
My tool appears to be only a tiny bit too small to fit onto the non-drive side cups but fits fine onto the drive side - hence why I am puzzled.
I never had this problem with the same tool on Shimano bottom brackets??
To further emphasise my problem the replacement bottom bracket from Superstar components also doesn't fit my tool on the non-drive side.
AhrggHHH I wanna ride my bike and I can't!!!
