I had a bit of a crash at the weekend and snapped a bit off my (carbon) frame. The bit in question is where the e-type mech attaches to to stop it rotating. It's not fixable so I've got a new frame on the way.
But...
I'd quite like to use the old frame as a 1x9. Can I just run a single chainring up front or will the chain jump off (it's a full suspension frame)? Is there a cunning component I can buy or do I have to get lateral with an angle grinder?
