From Element 6 to Element 13: Reynolds Redefines Trail Performance in Alloy
For more than 75 years, the Reynolds name has been synonymous with precision, reliability, and a relentless pursuit of performance. Known for mastering the sixth element, carbon, Reynolds now applies its wheel building expertise into aluminum platforms that challenge boundaries of performance and reliability. With the all-new A327and A329 Trail wheels, the Reynolds range sees two new alloy solutions that follow in the footsteps of their carbon brethren to redefine what exactly a fantastic trail wheel can be.
Built for the next generation of trail riders, the A329 (29”) and A327 (27.5”) Trail wheels bring the same Reynolds DNA of control, durability, and unmistakable ride feel to a new material. Purpose-built for the demands of today’s aggressive all-mountain and trail terrain, they prove that performance isn’t defined by what you make, but how you make it.

Trail Born. Trail Proven.
The new A327 and A329 Trail wheels were engineered from the ground up to meet the evolving demands of modern trail riders, those who climb with efficiency and descend with purpose. At their core is a completely new rim design featuring a 32 mm internal width, optimizing the tire-to-rim interface for greater traction, stability, and precision cornering. The STR tubeless-ready profile ensures an airtight seal, easy setup, and a secure no-burp fit with contemporary trail tire designs.
Constructed from 6069 aluminum, each rim features a precision-welded joint, that reduces weight while increasing impact strength and long-term reliability. Such a construction method not only ensures the structural integrity of the rim and overall wheel but contributes to a more airtight structure for tubeless set up. The result is a wheelset that feels light under acceleration yet confident through the roughest terrain, and it’s all backed by the Reynolds Lifetime Rim Guarantee.
Built to Go Big
he wide 32 mm platform gives riders a broader, stronger base for aggressive cornering and high-volume tire support, while reinforced sidewalls resist dents and pinch flats when the trail turns technical. The low-profile rim structure maintains compliance and comfort over roots, rocks, and chatter: creating a wheel that’s as forgiving as it is fearless. Whether climbing, descending, or hammering through fast flow lines, the A329 and A327 Trail wheels deliver the same composed, connected ride feel that defines every Reynolds wheel. This feeling of an enhanced ride experience does not occur randomly but rather derives from an intentional effort to develop wheels in an amazingly well-rounded manner, internally called RTV design process.
RTV: Reynolds Terrain Versatility
RTV is the Reynolds off-road design philosophy that defines how we engineer wheels for every discipline without compromise. It is the framework through which we balance all the forces that matter off-road: lateral stiffness, engineered compliance, tracking and handling, power transfer, weight, reactivity, and tire dynamics…to arrive at the optimal solution for each intended use. Rather than isolating a single performance metric, RTV considers the complete riding system, from rim profile and tire interface to material selection, layup strategy, and production technique. Every wheel developed under the RTV approach is validated through rigorous in-house laboratory testing and real-world riding at the highest levels of competition, ensuring that discipline-specific performance is matched by unmatched reliability. The result is not a generic “one-size-fits-all” wheel, but a precisely tuned solution that delivers the best possible blend of speed, control, traction, and durability for its terrain and purpose—without ever sacrificing the core Reynolds promise of long-term performance and trust.

ULD: Ultra Low Drag Development Approach
ULD is the Reynolds engineering approach that scrutinizes every freehub component, geometry, material, and interaction, to eliminate unnecessary drag and maximize efficiency. By refining pawl profiles, engagement geometry, spring rates, and surface finishes, Reynolds converts more rider input into forward motion without compromising durability. The result is crisp, reliable engagement and effortless speed, achieved through meticulous design rather than shortcuts.
Trail Ready. Rider Approved.
The new A327 and A329 Trail wheels were designed for riders who demand reliability without sacrificing speed, for those who see the climb as part of the reward and the descent as the true measure of their gear. From sort adventures to all-day epics, these wheels are built to take abuse, track precisely, and roll smoothly, again and again. With Reynolds’ renowned design philosophy, backed by a lifetime guarantee, the A327 and A329 Trail wheels represent a new benchmark in alloy trail performance.
Durability Backed by a Lifetime Promise
Every A309 XC rim is covered by the Reynolds Lifetime Rim Guarantee, the ultimate expression of confidence in craftsmanship and performance. It’s more than a wheelset; it’s a long-term partnership between rider and brand, built on trust earned over decades of innovation.
From carbon to alloy. From the 6th element to the 13th. Different material, same Reynolds mastery.
