You think something is wrong with my gxp bb?
I am gonna take apart the bike tomorrow and check out the BB and apply some grease.
If the BB is messed up any recommendations on a new one?
BTW cranks and BB were installed by an LBS.
The GXP system consists of two external bearing cups, a spindle attached to the drive side crank arm that passes through their center and a non-drive side crank arm holding it all together. There would be no way for any of it to "slip".
Usually when people think something is wrong with their BB, it turns out their cog/lockring is loose.
