Well here I go again with, what I guess is, another basic question but people here are great at
helping out a beginner.
I've always had a spot of chain rub when riding the middle chainring with the chain on the smallest
(8th) sprocket. I realise that this in one of those 'out of bounds' gears and it rarely gets used so
I've never worried about it.
I've recently noticed a spot of light chain rub however when riding with the chain on the 2nd from
smallest sprocket (7th). This only occurs when pedalling really hard (more of a mash really), the
sort of pedalling force that would probably suggest to a more experienced cyclist that they need to
change gear .
I appreciate that both the frame and chain can flex when pedalling (although I have an oversized
aluminium alloy frame - I don't know whether these flex or not) but I was wondering whether chain
rub is anything to worry about, does it suggest a mal-adjusted derailleur? The chainrings shift
crisply so I don't want to meddle with an otherwise working setup unless I have to.
The chain itself is fairly new and well looked after.
Thanks for any thoughts.
Kind Regards,
Paul.
