I've waited too long - if I crank hard, the chain slips in both the 50T and 39T rings. So I will get a new chain (I am embarrassed to find it's stretched by 3/8" at this point! I rode 50 miles today on a club ride - a lot of timely shifting into the granny gear kept things OK.
- Any good place to get good chainrings at a low cost?
- Can Ultegra rings be substituted for FSA?
- Are they better? (more durable, smoother shifting, whatever)
