Bottom Bracket Grinding
I have a sealed cartridge shimano bottom bracket that feels like it's grinding when mounted on the bike. If I remove the cartridge it spins normally. It starts to grind when I torque down the removable ring.
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
It's likely your bottom bracket shell faces aren't exactly parallel and when you tighten down the non-drive side cup, it warps the cartridge enough to bind slightly. Either have the bb shell faced or don't tighten down the nds cup too much. All that cup has to do is locate the cartridge so it needen't be torqued as much as the drive side.
