Ultegra set up 39/53 12/27
When I am in 39 /12 the chain rubs on the 53 ring.
What could be wrong ?
Is the 12 only good with the 53 ring ?
Thanks,
It's perfect, and don't use the 12/53 (nm)LC

you mean do not use the 39/12. the 53/12 is a sprinting gear and is ok. Never use small chainring with small sproket. The chain is stressed and will wear out fast. The same goes for the teeth in the chainrings.
