right fitted set 3 piece cranks new school jobbies with unsealed bb set got em running smooth as butter .but the bolt that hold the chaintring in place is catching on the bb cup .so removed them and added another spacer to bring the chainring out bit hey presto no rubbing but the chain is out of line with the freewheel .
?
does the chainring make type effect this or is it just leave the chainring bit further out so chain alignment isnt perfect .whichj then you can hear the noise it makes when pedalling as its rubbing on the freewheel sides and chainring sides of teeth not in middle
