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.
