Our all new Wide Range 10sp cassette is made for the MTB rider that needs just a little deeper climbing gear, but refuses to give up performance. Smooth shifting is sacred so we focused on the integrity of the shift all while extending the gearing in a fully finished comp level cassette. No awkward gearing steps, no unpleasant missed shifts… simply a proper, 10sp Wide Range cassette.  This is a full cassette and NOT an ‘Expander Adaptor.’   The goal was great shifting, no sacrifice, no compromise ‘Wide-Range’ 10sp MTB cassette, that you could use an unmodified 10sp MTB rear derailleur with. The 11-40 gearing allows this.

  • For SRAM/Shimano Mid or Long cage RD only.
  • Smaller cogs Steel and upper cogs machined 7075-T6 Aluminum Hard Anodized
  • 11-13-15-17-19-21-24-28-34-40
  • Designed with goal of proper, no sacrifice, no compromise ‘Wide-Range’ 10sp MTB cassette for consumers. Shifting integrity is priority.
  • Praxis did NOT want to be just another 'Expander/Adaptor' that many riders are resorting to. They wanted a full proper cassette.
  • Weight is 322g. Works on any 10sp MTB wheel with no 'rigging' or 'adaptors.' It's as simple as installing and adjusting your RD.

You're reviewing: Praxis Wide Range MTB Cassette

In 2007, well-known bicycle industry veteran David Earle set out to create a different kind of bicycle component company.

In the past he had been an integral part of many of the most well known R&D teams in the industry – Member of the original Bontrager Cycles, Sr. Design engineer at Specialized, Director of Engineering at Santa Cruz Bicycles, and many other individual R&D ventures for well known industry projects. It was simply time to branch out and focus on something that he had been working on for years: Drivetrain Components.

With his extensive expertise in metals and manufacturing, he launched Praxis Works with the goal of creating a unique brand along with a design and fabrication firm. With headquarters in Santa Cruz, CA and offices in Taiwan, Praxis’ sole purpose is to provide customers of all types with exceptionally designed drivetrain components that offer great performance and value.

Praxis Works has a very close association with Dragontech Manufacturing in Taiwan that allows access to exclusive metal forming techniques which have taken over 50 years to master. These innovative manufacturing methods combined with the in-house engineering team and testing facilities, make Praxis Works a new force in the cycling industry.
