Highlights
Why we rate it
Same gearing as XT for less
Identical 10-45T and 10-51T sprocket steps to the CS-M8100 at a lower price.
Ideal for GRX 1x
Works with GRX RD-RX822 in GS (10-45T) or SGS (10-51T) form.
Hyperglide+ shifting
Smooth, quick shifts even when you change gear mid-climb.
Tough steel build
Mostly steel sprockets make it a durable choice for muddy winter gravel.
Micro Spline fitment
Requires a Micro Spline freehub body to fit the 10T sprocket.
