Sunrace CSMX8 11 Speed Cassette

Sunrace CSMX8 11 Speed Cassette

The age of affordable 11 speed MTB components is here! As 11-speed drivetrains have become the norm on the trail, Sunrace has jumped into the cassette game, building this high-quality cassette with their trademark precision. The Sunrace CSMX8 11-Speed cassette is a lightweight upgrade option for HG splined freehubs, as its largest cog is constructed from 7075 aluminum while all the other cogs are cut from resilient steel. The MTB-specific wide-range gearing options include 11-40T and 11-42T.

Sunrace CSMX8 Cassette Features:

  • Speed: 11 Speed Shimano/SRAM compatible
  • Range: 11-40T, 11-42T
  • cogs: 11,13,15,17,19,21,24,28,32,36,40
  • Lightweight wide-range MTB cassette upgrade for HG splined freehubs
  • 7075 aluminum largest cog, all other cogs are hardened steel
  • Built with 6 cogs on 2 aluminum spiders, plus aluminum lockring and spacers.
  • Aluminum spiders prevent aluminum freehub notching
  • Compatible with Shimano / Sram Standard 8/9/10/11 speed freehub bodies (not SRAM XD driver compatible)
  • Weight: 398g - 40T, 405g - 42T

Great Cassette
I bought this cassette because it was considerably cheaper than the XT CS-M8000. Wow! Not only was it many grams lighter than the equivalent XT cassette, but it has a really great finish and overall quality, at least on par with XT. The shifting paired with a SRAM X1 chain is solid and smooth as you would expect. The red spider looks really cool but might not be everyone's flavor.

Time will tell if its durability holds up like XT but after a few rides it's still going strong.

PROS: Attractive Design, Lightweight, Easy To Install, Durable

BEST USES: Mountain Biking, Racing

Swapped out my old X9 double system for a 1 x 11 using this derailer , GX -11 shifter ,Sunrace CSMX8 11 Speed Cassette ,SRAM PC-X1 11 Speed Chain . So far it's worked like a champ. Great price , clean shifts, looks good too. Easy to install. Pretty light weight.. Well worth the money , I love the upgrade.

Can I run this with a Shimano XT rear derailleur and ultegra road shifters?
A shopper on May 17, 2017
BEST ANSWER: You would need 11-speed shifters and 11-sp rear derailleur, but technically yes
Will these shifters cover an 11-42 gear range? Specifically the Sunrace CSMX8 11 spd cassette?

Shimano Ultegra ST-6800 11-SPD Shifters
Shimano Ultegra ST-6800 11-SPD Shifters
BEST ANSWER: The rear derailleur is more important than the shifters. As long as you use Shimano road shifters with Shimano road derailleurs you will be fine. Currently, Shimano does not make a derailleur that supports a 42t cassette. You can use a wolftooth roadlink and use a 40t cassette with a 1x chainring.
I just added an 11-40 cassette but the xo long cage that I have won't allow enough b-spring movement even with a longer screw. Which derailleur should I get? it's a 3x9 btw.

SRAM X.9 9 Speed Rear Derailleur
SRAM X.9 9 Speed Rear Derailleur
BEST ANSWER: The 9 speed derailleurs I believe will only go up to a 11-34T max. If you are planning on running 11 speed derailleur you'll need at least a GX 11 speed rear derailleur and a SRAM 11 speed Exact Actuation shifter, or go with a Shimano 11 speed system. Call or chat us if you need some help!
This says it does not work with XD driver freehub bodies. Will this work with SRAM X.0 11 speed shifter / derailear if I use the shimano / sram 10 speed freehub body

BEST ANSWER: Yes it will.
