Mountain Bike Wheels

MTB XC - OUR NEW CROSS COUNTRY RACE RIM

Please Allow a 4-5 Week Lead Time for our carbon mountain bike rims. Each rim is built to order with our customers specifications in mind. Usually it takes about 2-3 weeks process time for the building of a rim.  

Our MTBXC Race wheels are available with ROL, White Industries, ONYX or Chris King hubs. If you are interested in DT Swiss hubs, please contact us and wE will set up a special order as soon as we are able to verify availability.

Our wheels are available with Shimano HG, Shimano MS (MicroSpline), and SRAM XD/XDR freehubs.

OVERVIEW

Our new Carbon Race rim overall depth profile fluctuates between 18.1mm and 21mm, creating an ribbed inner circumference. The combination of the stepped sidewall and shaped rim bed provide an increased amount of compliance. A finely-tuned Toray T700 layup features layers of carbon nanotubes in key areas to further the vibration damping properties. Carbon nanotubes increase impact resistance by 10% without adding weight. This rim rips on singletrack, yet is amazingly light and strong.

 This amazing rim is paired with our MTB hubs, which are durable, yet roll smoothly with their sealed precision bearings. Or, if you have a hub preference, we can build them up with White Industries, Onyx or Chris King hubs. DT Swiss hubs may also be available for your builds. The rims are laced with Sapim Race double butted spokes that are strong and light. We also use locking brass nipples for our builds for durability.  

Recommended rider weight limit is 298 lbs for the standard and 198 pounds for the flyweight. Above 240 pounds, we recommend the 32 hole Clydesdale build. 

Every wheelset is hand built to perfection in Colorado.  

The MTB XC Carbon Race Wheels can be ordered online with the 15x110 Boost front hub and a 12x148 Boost rear hub. Other hub combinations are available via special order. Contact us to check on their availability and to set up a special order.Email tom@rolwheels.com for any special requests.
