Reynolds ATR 650b Tubeless Disc Wheelset Info

The Reynolds ATR 650b Tubeless Disc Wheelset is Reynolds' more accessible entry into its All Terrain Road lineup, a carbon gravel wheelset built for riders who spend as much time on dirt and back roads as they do on pavement. ATR stands for All Terrain Road, and this 650b version sits below Reynolds' higher-end ATRx in price while sharing the same core design goals: a wide, tubeless-ready carbon rim that stays stiff and stable when the surface underneath you doesn't.

The rim measures 40mm deep with a 23mm internal and 32mm external width, a shape built to support the wider tubeless tires that have become standard on gravel and all-road setups, especially on the smaller 650b diameter where riders often run higher-volume rubber for comfort and traction. At 1,620 grams per pair, it's a genuinely light carbon wheelset for a wheel built to handle rougher terrain than a pure road rim, without asking you to trade away the stiffness needed to keep power transfer efficient on longer rides.

Reynolds builds the wheelset around its own Allroads Disc hubs, CNC-machined with a 10-degree engagement angle and 36 points of engagement — quick enough pickup to matter when you're threading through technical, low-traction terrain and need power on the ground the moment you start pedaling again. The hubs use a center lock disc interface and 12x100mm front / 12x142mm thru-axle spacing, and the freehub is available in a Shimano/SRAM HG-compatible body for 9-11-speed drivetrains (also compatible with Campagnolo) or a SRAM XD-R driver for 12-speed setups, so the wheelset works across most current gravel and all-road drivetrain standards.

Both wheels are built with 24 spokes, a count Reynolds uses to balance stiffness against weight rather than chasing the lowest spoke count possible — a sensible tradeoff for a wheel that's going to see washboard gravel and rutted farm roads rather than just smooth tarmac. The tubeless-ready rim setup lowers the odds of pinch flats and lets riders run lower pressures for extra grip and comfort without the weight or rolling resistance penalty of a tube, and the wide internal width keeps tubeless tires seated securely even as pressures drop.

The Reynolds ATR 650b Tubeless Disc Wheelset is built for riders who want a genuine carbon upgrade for a gravel or all-road bike without stepping up to Reynolds' ATRx pricing — long gravel days, mixed-surface road tours, and anything in between where a stiff, light, tubeless-compatible wheel makes the ride noticeably better. It's available in black, with your choice of Shimano/SRAM or SRAM XD-R freehub body to match your drivetrain.

The RA Perspective

We like the ATR 650b as the "smart money" pick in Reynolds' all-road lineup for riders who want a genuine carbon upgrade without paying ATRx pricing. The wide rim profile makes a bigger difference than people expect — tubeless tires seat more securely and hold air better at low pressure than on a narrower rim, which matters more on gravel than most riders think about until they've felt it.

The Allroads Disc hub's 36 points of engagement isn't flashy on paper, but on technical terrain where you're constantly starting and stopping your pedal stroke, that quick pickup is noticeable in a way a higher-engagement hub on a road wheel usually isn't.

The honest tradeoff is depth and aero performance — at 40mm, this is a wheel built for handling and comfort over rough terrain, not a wheel that's going to do much for you aerodynamically on a fast group ride. Riders coming from a lightweight aluminum gravel wheel will notice the stiffness improvement most on washboard and chatter, less so in outright speed.

This is the wheelset we point riders toward when they've outgrown their stock alloy wheels and want a genuine carbon step up for gravel or all-road riding, without needing race-level aero performance to justify the price.
