Carbon mountain bicycle trail rims were engineered to be the weapon of choice for aggressive trail wheel riders.

These rims are hookless bead design, tubeless ready. We upgraded the hookless design to the next level. Not like the traditional bead hooks "press" tires in, creating a rounded footprint. Our hookless rim is lack of the traditional bead hook, which allows tire sidewalls to form an optimal interface with the rim channel, resulting in a more stable and surfooted point of contact on the trail that maximizes cornering and handling characteristics without risk of burping or rolling. Directional drilling (angled holes) aids in alleviating the additional stress placed on the nipple bed interface.

Available sizes 27.5er (650b) and 29er, symmetric and asymmetric rim profiles, and several different rim widths:

26mm internal width & 25mm deep rim, asymmetric rim profile, 3mm offset.

The unique asymmetric profile balance drive and non-drive side spoke tension to create a more durable and long lasting mountain bicycle wheels.

650b - asymmetrical rim profile - TR726X, 25mm deep, 32mm external, 26mm internal, rim weight 370g.

29er - asymmetrical rim profile - TR926X, 25mm deep, 32mm external, 26mm internal, rim weight 390g.

29mm internal width & 23.5mm deep rim, symmetric rim profile.

It's most popular shape of carbon fiber mtb rim, for all mountain and trail mountain bicycle.

650b - symmetrical rim profile - TR729, 23.5mm deep, 35mm external, 29mm internal, rim weight 390g.

650b - asymmetrical rim profile - TR730X, 25mm deep, 36mm external, 30mm internal, rim weight 435g.

32mm internal width & 26mm deep rim, asymmetric rim profile, 3mm offset.

These new asymmetrical trail bike carbon rim features a 32mm internal width, making it suited to the new breed of wide trail tires in the 2.3"~2.8" range.

650b - asymmetrical rim profile - TR732X, 26mm deep, 38mm external, 32mm internal, rim weight 440.
