Reynolds TR 327 157mm Wheelset

The Reynolds TR 327 157mm Wheelset is a carbon trail wheelset built to the wider 157mm Super Boost rear spacing, giving frame designers room for shorter chainstays and better tire clearance on aggressive trail, enduro, and e-MTB platforms. At $1,449.99, it carries the same 27.5-inch rim and hub platform as Reynolds' standard Boost-spaced TR 327, just built to match bikes engineered around the wider rear end. For riders whose frame calls for 157mm spacing specifically, this wheelset is a way into carbon rim performance without stepping up to a flagship price point.

The rim measures 32mm wide and 19mm deep, a low-profile, wide-channel shape meant to widen tire footprint and improve cornering grip and power transfer over a narrower rim. Reynolds builds it with an asymmetric profile, offsetting the spoke bed so tension is more even between the drive and non-drive sides, which adds strength without adding weight — a detail that matters more on a wide-hub wheel, where spoke bracing angles are already asymmetric by design. The rim is hookless and tubeless-ready, shipping with rim tape pre-installed and valve stems included, so it's ready to mount tubeless tires out of the box. Reynolds lays the rim up using its CR3 TSS carbon process at its own facility and backs it with a lifetime warranty to the original owner.

Spokes are Sapim Sprint, laced 28 front and 28 rear in a 3-cross pattern with external brass nipples, chosen for a balance of vertical strength and lateral compliance rather than maximum stiffness. On a 157mm-spaced wheel, that compliance helps offset the steeper bracing angles a wider hub creates, keeping the ride from feeling harsh over repeated hits. The hub itself is a Reynolds/Ringle SRX MTN unit with a Centerlock brake interface, 3 pawls, and 12 degrees of engagement, quick enough to matter on technical climbs without needing the near-instant pickup of a premium ratchet hub. Freehub bodies are available for SRAM XD, Shimano Microspline, and Shimano HG, so switching drivetrains later doesn't mean switching wheels.

Reynolds lists the wheelset at 1,718 grams complete — solid rather than featherweight for a 27.5-inch carbon build, which fits the Super Boost platform's priorities. Bikes specced around 157mm spacing are generally built for descending capability and durability first, and this wheelset's stiffer rear-wheel geometry lines up with that intent. It's a fit for enduro and aggressive trail riders whose frame requires Super Boost spacing and who want carbon's stiffness and damping on rough terrain without paying flagship prices. Reynolds wheels ship sold in pairs, so this listing covers both wheels as a matched set.
