1×12 Road Ratchet

£66.50

This ratchet allows you to pair 10 or 11 speed mechanical SRAM shifters and a 1x-specific Exact Actuation™ derailleur with a 12 speed eTap™ AXS™ cassette and chain. You’ll gain all the advantages of greater gear range and closer gear ratios without the expense or weight of electronic shifting.

NOTE: You will need to replace your 11 speed jockey wheels with SRAM eTap™ AXS™  compatible ones. We offer some in our 1×12 Road Upgrade kit.

NOTE: On some older shifters, the reach adjuster will not spin freely when it bottoms out. Stop turning the reach adjuster screw as soon as you encounter resistance.

*This calculation is based upon SRPs for all components. It assumes that the purchaser already owns the SRAM shifters and derailleur required to use the kit.

**The calculation is based upon comparing Ratio/Rival™ 1 to Rival eTap™ AXS™ and Ratio/Force ™1 to Force AXS™
