Reynolds TR 307 27.5 Boost Wheelset Info

The Reynolds TR 307 27.5 Boost Wheelset brings Reynolds' carbon rim engineering to the trail, built specifically around 27.5-inch Boost-spaced mountain bikes. Reynolds produces these wheels in its own facility rather than outsourcing the build, and backs them with a lifetime warranty to the original owner — the kind of confidence a brand only offers when it trusts its own manufacturing process.

The rim itself is built from a layup of five different types of carbon, shaped into an asymmetric profile rather than a traditional symmetric design. That asymmetry lets Reynolds even out spoke tension between the drive and non-drive sides, which produces a stronger wheel overall along with better ride quality and durability over the long haul. The rim comes in at a 26mm depth with a 30mm internal and 36mm external width, wide enough to support the higher-volume tires that modern trail and all-mountain riding call for, and it's tubeless ready with hooked construction for a reliable seal and easy setup.

Reynolds builds the wheel around its own TR3 mountain hub, running 28 spokes front and rear for a balance of strength and weight, with a 3-pawl freehub and 10 degrees of engagement — enough for power to reach the ground quickly out of a technical corner or a punchy climb without a long lag between input and drive. Boost spacing front and rear (15x100 up front, 12x142 in the rear) widens the hub flanges compared to older standards, which increases lateral and torsional stiffness across the whole wheel. Freehub bodies are available for Shimano 9-11 speed or SRAM XD drivetrains, and the wheel runs on a Center Lock disc interface for rotor mounting.

On the trail, that combination of asymmetric rim construction and Boost spacing shows up as a wheel that feels stable and precise at speed rather than vague or wandering through rock gardens and off-camber sections. Riders who've put real trail miles on this platform describe it as stiff without being harsh — responsive when you need it, but still absorbing enough trail chatter that it doesn't beat up your hands and arms on longer descents. That durability holds up under real abuse too, with reports of wheels staying true through hard landings and rocky, technical terrain without denting or needing a trip back to the shop.

At $1,449.99, the TR 307 is built for the trail and all-mountain rider who wants genuine carbon performance and the strength to back it up, rather than a wheelset built to chase the lowest possible weight at the expense of durability. It's a strong match for anyone running a 27.5-inch Boost trail bike who wants a wheelset that can handle real riding day after day without babying it.

The RA Perspective

The TR 307 is the wheelset we recommend to trail riders who want carbon performance without the fragility that sometimes comes with it. Reynolds' asymmetric rim design isn't a marketing gimmick — evening out spoke tension between the drive and non-drive sides genuinely makes for a stronger wheel, and it shows in how these hold up over time.

On the trail, the character that stands out most is stability. These wheels feel precise and planted through rock gardens and off-camber terrain rather than deflecting or wandering, and they're stiff enough to respond immediately when you put power down, without transmitting every bit of trail chatter straight into your hands. That's a harder balance to strike than it sounds — plenty of stiff carbon wheels sacrifice comfort to get there, and this one doesn't.

Durability is where it really earns trust. Riders who've put real miles on this wheelset through rocky, technical terrain report they stay true through hard hits without denting or needing attention, which matters more on a mountain bike than almost any other spec on the sheet.

We'd point this wheelset toward a trail or all-mountain rider running a 27.5-inch Boost bike who wants a wheelset built to be ridden hard and left alone, not babied or swapped out after one bad rock strike. Backed by Reynolds' lifetime warranty to the original owner, it's a confident long-term investment for someone who rides often and rides real terrain.
