Hi all,
I have just installed a SRAM 970 cassette and a 971 chain.
Raceface cadence crank. Ultegra levers and mechs.
The chain seems to 'rub' or catch on the inner most cog. Despite whatever gear is chosen, it's still noisy. What gives? Chain width is standard, it's a 9spd setup, it always has been.
Any suggestions would be very much appreciated!
Cheers,
Jt
