Stan's NoTubes Crest CB7 29 Inch MTB Carbon Rim

Stan's NoTubes Crest CB7 29 Inch MTB Carbon Rim

Low profile carbon rim for cross country racing

All carbon rims are not created equal. If your carbon rim is too stiff, you're losing speed and risking tire pinch flats. The Crest CB7 rim with RiACT absorbs radial vibrations and damps impacts. It's a difference you can feel almost instantly. First introduced with the legendary Stans Valor rim, the impact absorbing RiACT technology has evolved to be more responsive and even more durable.

The Crest CB7's layup and rim shape allows for 10mm of radial compliance to absorb larger impacts. The rim also matches the Valor's strength while using less material to save weight. And when it comes to the lateral stiffness needed for steering precision and control, the CB7 layup delivers. Wider than the original Valor while still optimized for XC tire widths, the Crest CB7 keeps you in control and lets you roll faster.

The Crest CB7 also features the Bead Socket Technology. Combined with sealant, Stan's patented BST rim design has become the foundation of all current tubeless-ready systems. There are many imitations out there these days, but only one true BST tubeless system. The Crest CB7's tubeless technology means lighter, lower, faster accelerating sidewalls, easier inflation, and reliability that continues to set the benchmark for all tubeless systems.


  • Patented low-profile sidewalls and 23mm internal width
  • RiACT system absorbs impacts and rolls faster
  • Bead Socket Technology for easy tubeless setup and best reliability
  • WideRight rim design optimized for 2.00 - 2.25" tires


RiACT rims a three times stiffer than Stans regular aluminum rims and absorb radial impacts to withstand bigger hits and roll faster.

The WideRight profile increases tire volume without negatively affecting tread shape or sidewall height.

Bead Socket Technology (BST) rims are designed to match the shape of your tire's bead to create a safer and more secure air tight interface.
