The A309 XC series is built upon the same engineering principles that define the 309 XC carbon line, a focus on structural integrity, lightweight design, and engineered compliance that delivers speed and control in perfect balance. By applying those same design philosophies to 6069 aluminum, Reynolds created a wheelset that retains the crisp, confident ride feel of its carbon sibling while adding the everyday dependability and value that alloy riders demand. Two versions, A309 XC Pro and A309 XC Expert, bring race-bred performance to the wider XC audience, translating Reynolds’ carbon expertise into a new, accessible form of excellence.

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.

The Ringlé SRX hub is engineered to deliver dependable performance with minimal complexity, making it a versatile foundation for high-quality wheel systems. At its core is a proven three-pawl engagement system designed for consistent power transfer and long-term durability across a wide range of riding conditions. Precision-machined internals ensure smooth, reliable engagement while maintaining efficient rolling performance.

The pawl geometry is optimized to balance quick response under load with reduced wear, allowing the hub to perform quietly and consistently whether climbing, accelerating, or navigating technical terrain. High-quality sealed cartridge bearings protect the internals from dirt, moisture, and trail debris, ensuring smooth operation and extended service life. The SRX hub shell is designed with strength and weight balance in mind, providing a solid platform that stands up to daily riding and demanding trail use without unnecessary mass. With compatibility across modern axle standards and drivetrain options, the Ringlé SRX hub offers dependable engagement, low-maintenance performance, and the durability riders expect from a Ringlé-engineered component.

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.

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.
