Maximum cassette size: We recommend a maximum 34-tooth cassette for the GRX 810 / 815 version to achieve optimal adjustment and shifting. 36 teeth maximum for the GRX 820 version.
Chain length: We strongly advise equipping your bike with a new chain to accompany the installation of your new derailleur Nova Ride. We recommend adding 2 to 4 links compared to your previous chain.
For a derailleur compatible with the GRX 822 12-speed, please look towards the Shimano SLX / XT / XTR / GRX 822 derailleur.
