Fast and light Ready to Roll wheels for touring, audax, all road, and cyclocross. A real do-it-all wheelset that’s light on the scales and sturdy on the roads.

Built with utterly bombproof DT Swiss RR421DB Asym Rims and Hope RS4 Centrelock Hubs.

We particularly like that the RR421 rims are asymetric, which gives better bracing angles to the spokes for superior tension balance.

The 20mm internal width is ideal for tyres 25-35mm wide. And, of course, they’re tubeless ready.

RyanBuildsWheels Ready to Roll wheelsets

All of our Ready to Roll Wheelsets are lovingly laced at the RyanBuildsWheels workshop in Bristol, UK. They’re made to order and can be shipped to almost anywhere in the World.

Our Ready to Roll Wheelsets are made from a handpicked collection of our favourite hubs, rims, spokes and nipples. These parts have been carefully selected to offer us the best quality of build and our customers the best quality of ride. They’re built to balance strength, weight, longevity and value.

These wheelsets offer all the benefits of handbuilt, custom wheels without the added cost of a fully bespoke build.
