Hello,

Just received my Stronglight CT2 130mm PCD 53T/39T from Bike24 and I realized that they are 10/11 speed rather than 9/10 speed as I expected. The rest of my drivetrain is all 9 speed and I was wondering if I would see any degradation in shifting quality.

I bought the rings to improve shifting quality over some low-end shimano rings so shift quality is the main motivation for installing new chainrings.

Should I sell the stronglights and get some TA Hegoa? I found the 53/39 for $100 or so.
