Campagnolo Super Record EVO Chainring $189.99
Campagnolo's Super Record EVO Chainring is an 11-speed outer ring for those who want to upgrade their 10-speed cranks, or who need to replace a worn-out ring on their 11-speed cranks.
It is not a 10-speed ring re-labeled. For one, the teeth are 0.4mm narrower. There are also four separate ramp systems built into the ring, rather than the two upshift and two downshift zones apiece on the 10-speed rings. These 11-speed rings will work with most current 10-speed Campagnolo cranks. The two exceptions are Centaur and Veloce cranks, where the spacing is different.
If you are upgrading from 10 to 11-speed, you may be tempted to stick with your 10-speed rings. Campy can't guarantee that your shifting will work with the older 10-speed rings. The slight difference in the width of teeth could result in chain suck.
The Campagnolo 11-speed outer chainring is available in a compact-sized 50 tooth with a 110mm bolt circle diameter.
