Your cart is empty.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.

Got this cassette to expand the range on my old MTB that I converted to a gravel bike. I didn't have to upgrade to the newer style freehub body, so I could just swap this for the old cassette and put on a new derailleur and I was good to go. Shimano always shifts smoothly, even in their more budget-oriented products. You can easily spend 5x as much money for a 12-speed cassette with basically the same range (which also would have required me to buy a new shifter, and freehub) or you can go this route. This is cassette is definitely a great bang for your buck.

Great cassette for low price. As usual, make sure this actually fits with your rear derailleur, both for 11 speeds and max compatible sprocket size.

Heavy but allows you to go to a 51t climbing gear in 11 speed. You should also account for at least a new RD as native 11 speed RDs are not going to be happy going way outside of their range up top.Ratios are good, usually there's not enough bandwidth to make a good spread but this works fine.

I have about 500 miles on this cassette for a road bike and it's working great. I did also have to replace the derailleur to accommodate the dish plate sized 51T sprocket, but it's really nice for climbing the large, steep hills around my house.

I Order this cassette on Tuesday and had it in Thursday. I fit great no defects or missing parts. The description is spot on. It will fit your Shimano Deore 5100.

Great cassette. Durable and good shifting. No issues from my end with performance. Sure it’s not the lightest, but it is well performing.

I had been suffering with a popular budget brand cassette for 2 seasons. Shifting was lottery - you never knew what you would get. Admittedly, I am running an extreme setup: 2 by 11 with a 16 tooth difference on the crank. Adding this cassette made shifting normal - one click one gear. I feel dumb for not trying a Shimano cassette sooner. Not running a Shimano chain either BTW - maybe will try that next.

On the heavy side but is the best option for converting to a 1 by with a non-boost frame. My rig was 3x9 stock, I upgraded to 2x11 and when this cassette came out I got rid of the front mech altogether. Shifts great, has decent road speed and climbs like a beast with a 34T ring up front.
