Why We Like The CS-M5100 Cassette
With a focus on gear steps to help maintain performance and maximum cadence control, Shimano’s CS-M5100 Cassette for 11-speed drivetrains keeps you churning the correct cog no matter the terrain. The wide gear range may postpone your drop-in for the 12-speed group a bit longer, as the M5100 is undoubtedly designed to be a dependable workhorse and a worthy weekend racer. With terrain specific options, the 42-tooth or 51-tooth, you can ride long tempo climbs or have bail-out, switchback crusher. And the 11-speed design still allows a fast downhill 11-tooth cog to motor back to the trailhead.

- I've used it several times
- Size Bought:
I went through 2 Sunrace 11x50 cassettes in 4 years and was looking for a better option Until Shimano came out with this cassette the best they had was a 11x46 with a huge jump to the 46 This new 11x51 works great with my 1x XT 8000 drivetrain Just needed a tweak of the B screw Shifts are flawless and much better then the Sunrace Very happy

11/51 cassette happy
- I've put it through the wringer
The 11/51 provides a wide gear choice. Makes the knees happy. Shifts are crisp and precise. You should run a steel freehub, as the cassettes splines will gouge a aluminum freehub, and ruin it. With steel freehub, no problem. The cassette holds up extremely well in all conditions. I run it on a Pivot Mach 429 trail, 2x11 drivetrain. Riding trails from Michigan to Colorado to Arizona. I have worn out 2 cassettes in 3 years, due to rocks in Utah and Arizona.
