Reynolds AR58 Tubeless Wheelset

The Reynolds AR58 Tubeless Wheelset is built for road riders and triathletes who want a genuine aero wheel without giving up rim brake compatibility. Reynolds shapes the carbon fiber rim to a 58mm depth, deep enough to make a real difference in still air and at speed, while keeping the wheel practical for everyday road riding rather than limiting it to race day only. It's a wheelset built around one job — cutting through the air efficiently — without losing sight of everything else a rider needs from a wheel they'll put real miles on.

Reynolds pairs that depth with a wide rim profile: 19mm internal, 28mm external. That width matters more than it might seem — a wider rim supports a rounder, higher-volume tire shape, which improves grip and lowers rolling resistance compared to a narrow rim forcing a tire into an unnaturally tall, narrow profile. The rim is tubeless ready, so switching away from tubes is straightforward, and the wider internal width gives tubeless tires more air volume to work with for a smoother, more comfortable ride over rough pavement.

Because this is a rim brake wheelset, Reynolds pays particular attention to the brake track. The Ctg2 brake track is built to be 30 percent more heat resistant than Reynolds' previous rim brake tracks, which is the spec that matters most on long descents where sustained braking builds heat in a carbon rim. That heat resistance is what keeps braking predictable mile after mile rather than fading when you need it most. The wheel runs on 12x100mm front and 12x142mm rear thru-axles, a stiffer standard than traditional quick release that's increasingly common on newer rim brake road frames, giving the wheel a more solid connection to the bike under hard cornering and braking.

Spoke counts are 20 up front in a radial pattern and 24 in the rear laced two-cross, a setup that keeps the front wheel light and aerodynamically clean while giving the rear the extra spoke support it needs to handle drivetrain torque. Reynolds' own GW RRB hubs use a 10-degree engagement design, so power gets to the road faster after every pedal stroke, particularly noticeable out of tight corners or in a fast-moving group. Freehub bodies are available for Shimano/SRAM 9-11 speed, Campagnolo, and SRAM XD-R, covering nearly any drivetrain a rider is likely to be running. All told, the wheelset comes in at 1,700 grams for the pair — not the lightest option on the market, but a fair tradeoff for the aero gains a 58mm rim provides.

That aero profile earns its keep at speed. Riders who've spent time on this rim depth describe noticeably less effort required to hold pace once above roughly 20mph, and the crosswind behavior at this depth stays composed — riders report the wheel handling gusts and shifting yaw angles with a bit of side pressure rather than any real steering interference. There's a small amount of lateral flex under hard out-of-saddle efforts, which is typical of a wheel built around aero performance rather than outright climbing stiffness, but it's not enough to be distracting in everyday riding. At $1,449.99, the AR58 is a strong option for road racers, triathletes, and time trial competitors who want a genuine aero upgrade on a rim brake bike, and for any rider who spends more time at speed on flats and rollers than grinding up sustained climbs.
