Ratio Technology SR52 Cage for SRAM 1x Mechanical


Use our derailleur cage to increase the maximum sprocket capacity of your SRAM 1x derailleur for wide-range 1×11 or 1×12 drivetrains. Convert a SRAM 1×11 derailleur with a 28t, 36t or 42t limit into a wide-range mech ready for 52t cassettes. If your derailleur is X Actuation™, add a Ratio Cable Fin to use it with your road shifters.

If you’re not sure which kit or parts you need, please check our Kit Guide.

This derailleur cage features 7075 aluminium plates with Delrin jockey wheels, all machined in house by Ratio in the Lake District, UK. #madeinthelakes

The cage is compatible with mechanical SRAM 1×11 derailleurs with Type 2.x and Type 3 clutches including both road & MTB versions, as well as SRAM 1×12 Eagle derailleurs. Electronic Eagle™ AXS™ derailleurs are not compatible.

Designed to increase the capacity of your 1×11 derailleur, or as a direct replacement for damaged Eagle derailleurs, this cage makes your mech compatible with cassettes with up to 52 teeth. It comes pre-fitted with 12t upper & 14t lower jockey wheels, both spinning on sealed Enduro bearings. The jockey tooth profile builds on knowledge gained designing our Ratio Ring, the lower jockey also features narrow-wide teeth for improved chain retention.

Want to use this cage to upgrade your 1×11 SRAM Road drivetrain to wide range 1×12? We offer it as part of our 1×12 Wide Ratchet & Cage Kit which also contains our 1×12 Wide Ratchet.

For information on how to install the cage, see our SR52 Cage instructions.
