Hi,
After much advice received here on mtbr I've finally gotten round to converting my 3x10 to a 2x10+bash. The chainring replacement went fine, replacing SLX 24/32/42 with Blackspire 26/38 and a Hope bash... but when I try to replace the drive side crank it noticeably grinds when rotated. The chainrings fitted perfectly with the existing bolts so there's no protruding parts anywhere, it seems to be the spindle against the BB that is making the noise.
The BB was perfectly smooth before I removed the crank and the bike is only 6 months old so it can't be knackered already. Is there a knack to re-fitting the crank that I'm missing? It's baffling me.
Many thanks in advance.
