Ready to Rip

Throw caution to the wind. Point and shoot. Get rowdy, be playful and have fun. Because you only live once and trails are meant for ripping.

Don’t let the aesthetic of paired-spokes fool you. The balanced spoke tensions and increased stiffness that characterizes all our wheels also applies on the trail. If you live to rip but don’t want to sacrifice climbing speed and wheel weight to do so, the Black Rock is for you. It features a hookless, all carbon clincher rim built tough enough to handle whatever you throw at it. It’s then centered around our US made XST hubs with a CNC titanium freehub body and, like all of our wheels, is built in Eugene, Oregon.


*We do our best to ship your wheel order ASAP, but because many wheel orders are built to order, please allow up to one week for shipment once your order is processed.  Custom orders may take up to two weeks.
