All but one of the cogs on this Box Two 11-Speed MTB Cassette is made of hi-tensile steel. The biggest cog is made of 7075 aluminum, but despite the amount of steel, this cassette helps bring the steepest climbs within reach by providing a massive gear range of 418 percent. Two aluminum carriers hold the largest seven cogs while four individual cogs are separated with aluminum spacers. Each cog has ramped teeth for improved shifting. Box cassettes are compatible with all major 11-speed chains and traditional MTB freehubs but note that they are not compatible with XD Drivers.


  • Super wide ratio provides optimal range for Box drivetrain systems & other 1x systems
  • Lightweight wide-range MTB cassette upgrade for HG splined freehubs
  • 7075 aluminum largest cog, all other cogs are steel
  • 6 cogs on 2 aluminum spiders, plus aluminum lockring and spacers
  • Box and SRAM derailleurs are generally compatible, Shimano derailleurs require a longer B-tension screw

Box Two MTB Cassette (Black) (11 Speed) (Shimano/SRAM) (11-46T)
I had a race to go to and my old Cassette was trashed so picked this Box Two 11-speed MTB up from Performance Bicycles because they had the best price and quickest shipping and from all the reviews I read it seemed like a solid choice. I was happy with the looks of it when I opened the package, I wanted to weigh it quick but I didn't have my scale with me but felt pretty light compared to the cassette I was replacing. Installed with easy, flawless performance and had me race ready by the weekend. I did a inspection after the race and still looked brand new, no unusual wear or marks. Super satisfied with my purchase.
