1 x 12 Road Kit Guide

1×12 Road

What’s it for?

The 1×12 Road kit allows you to upgrade your SRAM 1×11 drivetrain to close ratio 1×12 using SRAM’s road AXS* 12 speed cassettes (Red*, Force*, Rival* and XPLR*) and SRAM Flattop* chains. These cassettes have proprietary, variable sprocket spacing, so the 1×12 Road kit is specific to these SRAM road 12 speed cassettes.

What’s in the kit?

In the kit you’ll find a 1×12 Road ratchet for your SRAM road shifters and a set of 12 tooth jockey wheels for your SRAM road 1x derailleur. These jockeys allow you to run SRAM’s Flattop* chains, which are a requirement of the road 12 speed cassettes. Our jockeys run on long-lasting stainless Enduro bearings.

Green – Recommended

Amber – We’ve tested some of these and, for derailleurs in particular, some options will be an issue. These issues are related to jockey wheel clearance and total derailleur range of movement.

Red – Not recommended
