C 38
Performance to the people
what it’s for, why it’s great
Smashing down the cost-of-entry barrier, the C 38 brings carbon fiber high performance to the real world. It’s a versatile all-rounder equally at home crushing gravel washboards and summiting alpine passes. Exceptional aerodynamics, modern 21mm width, tubeless-ready, durable and lightweight, the C 38 outperforms wheels costing twice as much.

Millimeters that matter
Wider tires roll faster, and are more comfortable, than narrow tires. The tubeless ready, 21-mm internal width of the C 38 is optimized for use with modern, wider tires, providing them with the right amount of sidewall support to facilitate surefooted handling in all conditions. At a depth of 38mm, the C 38 rim is a great handling, lively climbing, robust all-round performer that also aerodynamically outperforms many deeper, aero-specific rims.
Premium quality hubs and spokes
With two main goals in mind—long life and easy serviceability—we looked to Switzerland. The C 38 uses an ultra-reliable, rapid engagement DT 350 star-ratchet freehub for smooth power transmission and long-term dependability. Similarly, DT Swiss Competition spokes were chosen to lace hub to rim, and finished with brass Pro-Lock nipples.
Hand built quality throughout
The premium components that make up this wheel are assembled together into the final product by hand. They are laced, tensioned, checked, and tensioned again by practiced, professional craftsmen: an added layer of quality control that machines cannot match.

How we made it
Handbuilt
There's no substitute for the hands-on experience and meticulous attention to detail that a human being brings to the craft of wheel building. While many wheels on the market are built by machines, Roval wheels are always built by people: from lacing the hubs, to equalizing spoke tension, to truing the wheel to lateral and radial perfection.
Composite shop
Before a wheel goes into production, we do all of the engineering, prototyping, and iterating in our Northern California innovation center. This includes machining the massive molds as well as laying up and producing the prototype rims. This kind of integrated, hands-on approach accelerates development and enables optimization that’s simply not possible any other way.
