Reynolds TR 367 S 27.5 Boost Wheelset

The Reynolds TR 367 S 27.5 Boost Wheelset is a carbon trail wheelset built for 27.5-inch mountain bikes running Boost hub spacing. It sits in Reynolds' TRs tier, a step up from the brand's standard TR line, and that "S" designation carries real differences in the build rather than just a name change.

The rim is Reynolds' asymmetric carbon design, built with the brand's layered carbon construction that mixes several distinct carbon fiber types across different areas of the rim to balance strength and weight rather than relying on one uniform layup. The asymmetric profile shifts spoke tension to be more even side to side, which Reynolds uses to build a stronger, more reliably tensioned wheel. Rim dimensions land at 26mm depth with a 36mm internal width and 42mm external width, a shape designed to support wider trail tires at lower pressures for better grip through corners and over rock gardens. The rim is tubeless-ready with a hookless bead profile, which Reynolds designs for easier initial tire seating and a reduced risk of tubeless burping compared to a hooked bead. Weight comes in at 1,725 grams for the pair.

Reynolds builds the wheelset around its TR6 Mountain hub, a 100% CNC-machined hub with 5-degree engagement, which means less rotational play between stopping pedaling and the wheel responding, useful when you need power down quickly on a technical climb or out of a tight switchback. The TRs tier upgrades to bladed Sapim CX-Delta spokes with alloy nipples in place of the round spokes on the standard TR line, a change Reynolds makes for a stiffer, more aerodynamic spoke without adding weight over the equivalent round-spoke option. Spoke count runs 28 front and 28 rear. The wheelset uses a center lock disc brake interface and is built around Boost hub spacing, with freehub options in Shimano 9-11 speed or SRAM XD depending on your drivetrain.

Reynolds backs the wheelset with a lifetime warranty on the rims plus a 30-day customer satisfaction guarantee, and includes a five-color decal kit so a rider can match or customize the look of the wheels rather than being locked into one graphics scheme. That combination of warranty coverage and a wheel built specifically to hold up to trail riding is core to how Reynolds positions its mountain lineup — wheels meant to survive real trail use over multiple seasons, not just perform well on a first ride.

This wheelset suits a trail or all-mountain rider on a 27.5-inch bike who wants a genuine step up in wheel stiffness and hub responsiveness without moving into enduro-weight territory. The wide rim bed rewards a rider running larger volume tires at lower pressure for grip on loose or rocky terrain, and the quick-engaging TR6 hub pays off most on technical, punchy climbs where instant power transfer matters. For a rider replacing a heavier alloy wheelset or an older, narrower carbon wheel, this is a meaningful upgrade in both ride quality and long-term durability.
