Kit Guide

Ratio upgrade kits help you keep your bike up-to-date without the waste and expense of replacing otherwise functional parts, whether that’s switching from 11 to 12 speed, 10 to 12, wide range or narrow.

We’ve compiled these guides to help you understand the options that we’ve made available. Please use the menu or gallery below to find the correct guide. If you can’t see an answer to your question, just drop us a message. You can also check out our Support page for instructions and video guides.

Green is our recommended option. Amber has been used by some customers but is currently un-tested by us and a red part has been confirmed to be incompatible.

Please note that Ratio Technology Limited is not in any way affiliated with, sponsored or endorsed by SRAM, LLC.
