1×13 C
What’s it for?
The 1x13C Upgrade Kit allows you to operate a Campagnolo 13 speed Ekar* cassette and chain with your existing SRAM road 10 or 11 speed shifters and 1x-specific SRAM Exact Actuation* derailleur. Pair with our Ratio Ring for a 13 speed drivetrain with a minimum of new components.
The kit is specifically designed around the variable sprocket spacing of Ekar* cassettes. Other 13 speed cassettes, such as SRAM Red XPLR*, are considerably wider and will not work with our kit.
What’s in the kit?
In this kit you’ll find a 1x13C ratchet for your SRAM road shifters, with shift spacing specially designed for Campagnolo Ekar* cassettes, as well as a pair of Ratio 12 tooth jockey wheels with stainless Enduro bearings and labyrinth seals, specifically designed for Ekar* chains.
