I just built up an old road frame I've had for years and the chain is rubbing on the seat stay.
I've had this frame set up with a couple different 9sp drivetrains, but its now 11sp.
Maybe the 9sp drivetrains had 12t cogs for the smallest one?...I don't think so, but there was no rub on those setups.
Question- does anyone who has been building since 126mm dropouts were used now angle the stays differently to accommodate an 11t cog?
I was surprised this is an issue since I've built probably 6 different 80s road frames with 11sp drivetrains and none have had this issue.
Guess I'll turn this into effectively a 10sp cassette and lock the small cog out?
Or save for a 12-28 duraace cassette that costs $285!! <--nope, not doing this.
