Reynolds TR 367 27.5 Boost Wheelset

The Reynolds TR 367 27.5 Boost Wheelset is built for riders who want a trail wheel that still carries some of the speed of a cross-country build. It sits in Reynolds's TR lineup as the more affordable route into the brand's carbon mountain wheels, aimed at a specific kind of rider: someone climbing fire roads and singletrack all day, then wanting the wheel underneath them to hold up when the trail turns rough. Boost spacing widens the hub flanges, which adds torsional stiffness to the whole wheel, and that stiffness is the foundation everything else on this wheelset is built around. Reynolds designs its Trail platform around the same idea across the line: light enough to climb well, but built to take repeated hits without the ride quality falling apart underneath you.

Wide, Asymmetric Carbon Rim Construction

The rim is where most of that trail character comes from. Reynolds cuts a low profile, wide channel into the 367, which lets you run larger tires at lower pressure without the tire folding under load in a corner. That extra volume translates directly into grip on loose terrain and a smoother ride over rock gardens and root sections, since the tire has more air to absorb an impact before it reaches the rim. The rim itself is asymmetric, offsetting the spoke bed to even out spoke tension between the drive and non-drive sides, which improves stiffness and durability compared to a symmetric design under the same load. Reynolds lays the rim up from five different types of carbon, a construction it calls CR3, aimed at balancing strength against weight rather than chasing the lowest possible number on a scale. The same low-profile, wide-channel shape is what Reynolds points to across its Trail range as the reason for quicker cornering speed and better trail feel compared to older, narrower rim profiles.

Hub Engagement, Spokes, and Tubeless Setup

Power gets to the ground through Reynolds's TR MTN hubs, CNC-machined and built for 10 degrees of engagement. That's fast enough to matter on technical, punchy trail climbs, where a slow-engaging hub can cost you momentum right when you need it most, and it's noticeable the moment you stand up to clear a root ball or a loose, stepped section of trail. The hubs are laced with Sapim's double-butted Sprint spokes, which Reynolds uses across its TR line for a combination of durability and ride compliance rather than outright minimum weight. The rim itself is tubeless-ready and hookless, so tires seat and inflate without a compressor fight, and the hookless profile is harder to pinch or puncture on a hard rock strike than a hooked rim under the same impact. A center lock disc mount rounds out the build, spreading braking heat more evenly across the rotor interface during long, sustained descents.

Built for 27.5-Inch Trail Riding

The 367 is built specifically around 27.5-inch wheels, a size that still holds real appeal for riders who value quick, flickable handling on tight, twisty trail systems over the rollover advantage of a 29er. On a switchback-heavy descent or a trail with a lot of direction changes, that smaller wheel diameter can make the bike feel more willing to change line without extra input. It ships with a choice of Microspline, Shimano, or XD driver bodies, so it slots into most current drivetrains without forcing a freehub swap. Reynolds builds its wheels in-house, from raw carbon to finished rim, and backs that process with a lifetime guarantee on the rim to its original owner, the kind of warranty that matters more on a trail wheel than almost anywhere else in a bike build.

Who It's For

Riders who'll get the most out of the TR 367 27.5 Boost Wheelset are the ones pushing a trail or short-travel enduro bike hard enough that a lightweight XC wheel would eventually fail them, but who don't need or want to pay for Reynolds's flagship Blacklabel build to get there. It's a wheelset built for real trail miles: technical climbs, rock gardens, and descents where a stiff, well-supported rim matters more than shaving the last few grams off the total weight. For a rider building up a 27.5-inch trail bike who wants carbon performance without carbon fragility, the 367 is the wheelset built to survive the terrain it's designed for.
