Trickle-down magic.

We're not afraid to assert that Shimano is the de facto leader in trickle-down technology. The brand consistently executes progressive changes across its componentry in a methodical, rather than frantic, fashion, then spreads those changes across the rest of its line like a fairy godmother in a familiar story. The brand bestowed this same magic on its redesigned SLX line, turning the workhorse line into a shiny group of moving parts that look and perform far beyond what their price suggests. The SLX CS-M7000 Cassette may not be the star of the show, but it didn't miss out on any of the magic dust.

Crafting the cassette with an aluminum spider, Shimano shaved grams from the design compared to past versions, then constructed the cogs with a durable mix of aluminum and steel. In all, Shimano aimed the new SLX drivetrain at the ever-changing lineup of trail and off-road adventure bikes featuring wider spacing and bigger tires. It also wanted to deliver 11-speed to riders who aren't ready to take a pro-level chunk out of their wallets to pay for XT just yet, and in true Shimano style, didn't trade functionality for a lower price point.

Sweet Gear Range

  • Familiarity: I've put it through the wringer

As with many others, I picked up one of these to convert by road / cross bike into a 1X set up. This offers a nice wide gear range, reasonable weight and solid value.

rock solid

Inexpensive replacement or build up for your shimano group. bought a couple over the last few years and always been rock solid for us.

After about 400 miles, my new Sram NX equipped Ripley LS started making horrid drivetrain noises. It caused me to write off the NX as junk, and plan to just replace it all with Shimano. I decided to first try the Sram stuff with this cassette, and voila! The bike is now whisper quiet again and shifts perfectly.

Heavy But Good

  • Familiarity: I've used it several times

My only complaint on this cassette is that it's on the heavy side, the price certainly compensates for that though. Beyond that shifting performance is good, based on experiences with similar cassette durability will be good as well. The 11-40t is a great gear range for me without moving to giant jumps between gears.

works great

    solid cassette, shimano so you cant go wrong, was very surprised on the size of the 46t chairing its massive!

    Works Great

      Same gear range and quality as XT at a slightly lower price point. If you are looking to upgrade to 11 speed this is a great option.

      • Familiarity: I've put it through the wringer

      I was looking to drop the front derailleur on my beater CX/Gravel/Commuter Diamondback Haanjo trail and realized I could make my current Ultegra 11sp rear derailleur work with a Wolftooth Roadlink and this SLX 11-40 cassette. I went with the SLX to save a little dinero, even though its a bit added weight.

      For the record, my drivetrain previously was a FSA 2x crankset, an Ultegra front and rear (medium cage I think) derailleur, and a 11-32 cassette. I went to the Rival 1 crankset, an SLX 11-40 cassette (Item #SHI00C1), and a Wolftooth Roadlink (Item #WFC0006). I'm running it with a Sram 11sp chain and it works flawlessly. I do wish the Ultegra derailleur had a clutch to keep chainslap down a bit on rougher CX terrain, but the shifting itself works flawlessly with the Wolftooth Roadlink.

      If you have any questions on whether or not this is right for your derailleur or updating your drivetrain to a 1x, don't hesitate giving a shout and I'd be happy to help! My direct line is 801.204.4547 or you can reach me at

      Will the 9 speed 42 tooth cassette work with a regular 9 speed setup ?

      Does the job!

      • Familiarity: I've used it several times

      I wore my chain out and took my old XT cassette with it. I replaced it with this here SLX for a tiny weight penalty, but it works just the same!
