Reynolds ATRx Tubeless Disc Wheelset

The Reynolds ATRx Tubeless Disc Wheelset is Reynolds' answer to the rider who refuses to split their quiver. ATR stands for All Terrain Road — a design philosophy that starts with road-caliber aerodynamics and extends it into gravel, dirt, and mixed-surface riding without asking the rider to compromise one for the other. The ATRx is built on a 40mm carbon rim with a wide tubeless-ready profile, Reynolds' CR6 carbon layup, and the Allroads hub system — all for a wheelset that covers an unusually broad range of riding conditions from a single setup at $1,699.99.

Carbon Construction and Rim Profile

The rims are built using Reynolds' CR6 carbon layup process, which Reynolds describes as delivering lightweight construction paired with the structural durability needed to back every rim with a lifetime guarantee. Reynolds builds and assembles these wheels entirely in-house, which means the carbon specification, spoke drilling, and final build all come out of the same facility under the same quality controls. The 40mm rim depth sits in a useful middle ground for mixed-terrain riding: deep enough to capture aerodynamic advantage on open road and fast gravel sections, shallow enough to remain manageable in crosswinds and on technical descents. Reynolds developed the ATR rim shape specifically around the larger tire sizes that gravel and all-road riding demands, studying the interaction between rim and tire at multiple wind angles to optimize stability alongside speed. The result is a snub-nosed aero profile that accounts for the wider tire bulge rather than assuming a narrow road tire.

Tubeless Construction and Tire Compatibility

The rim uses a hooked tubeless-ready construction with a 23mm internal width and 32mm external width. The hooked bead seat gives a wider range of tire pressure compatibility than hookless designs and works with essentially any tubeless-ready tire, not just those specifically rated for hookless rims — Reynolds recommends a maximum pressure of 90psi. The 23mm internal channel fits tires from approximately 28mm up through 45mm, covering road tires, mixed-terrain 30-35mm rubber, and purpose-built gravel tires at the larger end. For a rider who runs a 32mm tire on road days and a 40mm tire on gravel events, the ATRx accommodates both without a wheel swap. Tubeless setup is straightforward: the rim tape, valve, and bead seat are designed to work together for a reliable tubeless seal that reduces the likelihood of flats on the type of rough terrain where tire damage is most common.

Reynolds Allroads Hub and Engagement

The hub is Reynolds' own Allroads Disc model — CNC machined aluminum with 36 points of engagement and a 10-degree pickup between each engagement point. The 36-point system provides a consistent, reasonably quick catch for the drivetrain under power, appropriate for the mixed-terrain climbing and acceleration that gravel and all-road riding demands. Both the front and rear hubs are designed around disc brake mounting only — center lock interface, no rim brake option. Front axle compatibility covers 12x100mm and 15x100mm thru-axle standards; the rear runs 12x142mm. Freehub options at purchase are Shimano/SRAM 9-11 speed or SRAM XD-R, covering the majority of current drivetrain standards. Campagnolo compatibility is available as a separate driver body. The hub body is also designed for serviceability — bearing and driver body replacement rather than disposal.

Build Specification and Weight

The ATRx is laced with 24 spokes front and rear, a spoke count that balances weight against lateral stiffness and durability for the varied loads gravel riding puts through a wheel. The completed pair weighs 1,620 grams — in a category where carbon gravel wheels range widely from under 1,400g to well over 1,800g, the ATRx sits at a competitive point that doesn't sacrifice structural integrity for a lighter scale reading. Reynolds backs the rim with a lifetime structural warranty, a policy they extend across the ATR lineup and one that reflects the quality control their in-house production enables. The wheelset ships in black and is available with either Shimano or XD-R freehub driver at purchase.

The ATRx is built for the road and gravel rider who wants one carbon wheelset that handles fast pavement, long gravel routes, and anything in between without asking for a different tire or a different wheel. The 40mm depth, wide-body tubeless construction, and broad axle and freehub compatibility make it a practical choice for riders who train across surfaces and don't want to maintain two setups to do it.
