The PF30a is similar to the PF30 standard, but the frame BB shell is 5mm wider on the non-drive side. PF30a system uses thin spacers and/or a wave washer between the bearings and the crank arms to take up any slack and micro-adjust the chainline of the crank
Well, at least that would be in keeping with PF30 BBs in general.I have a feeling that it's actually supposed to look like this - which frankly is terrible.
That doesn’t look goodI've only done about 600 miles on my Topstone but when washing the bike today I noticed this for the first time. It might have always been like that, but I can't recall. Is this normal?
Thanks!
