The Roval Alpinist CLX III is built for riders who value pure climbing speed, uncompromised efficiency, and featherweight handling. At just 1,131g for the set (with valves and tape), it drops 134g from its predecessor, making it the lightest Roval road wheelset to date. Engineered with Roval Aero Composite Spokes by ARRIS—20% stronger than steel yet significantly lighter—the system saves 103.5g while increasing durability and responsiveness. These innovations translate directly to real-world gains, as evidenced by Demi Vollering’s record-setting climb up the Tourmalet. Optimized around 28mm tires, the Alpinist CLX III balances low weight with modern tire volume for superior traction and control when the gradient steepens.

The front wheel showcases precision and minimalism with a 518g build weight, 21 spoke holes, and a 33mm-deep hooked carbon clincher rim measuring 26.5mm external and 21mm internal width. Its Roval low-flange hub features DT Sinc ceramic bearings for silky-smooth roll and centerlock disc compatibility for maximum braking confidence. The two-cross/radial (2:1) lacing pattern with composite aero spokes ensures stiffness while maintaining compliance on long ascents. Designed for tubeless or clincher setups, the front wheel supports tire widths from 24mm to 38mm with pressures up to 110psi (tubeless) or 130psi (tubed), delivering versatility without compromise. Every detail—from the 50mm alloy tubeless valve to hand-built assembly—underscores Roval’s pursuit of weight savings without sacrificing ride quality.

The rear wheel complements the front with a 613g system weight and robust 24-spoke construction. The 33mm-deep carbon clincher rim mirrors the front’s geometry, while the Roval low-flange hub integrates DT Swiss 180 EXP internals with a 36T ratchet engagement for fast, reliable power transfer on steep climbs. DT Sinc ceramic bearings provide frictionless performance, and the SRAM XD-R freehub body ensures compatibility with modern drivetrains. Rear lacing uses a one-cross/three-cross (2:1) pattern for a perfect balance of torque resistance and lateral stiffness. Together, the Alpinist CLX III wheels deliver unmatched climbing performance, ISO and UCI certification, and a 275lb rider weight limit—all backed by Roval’s limited lifetime warranty. For riders chasing polka dot jerseys or simply the fastest way uphill, this is the ultimate lightweight wheelset.

Beyond the numbers, what sets the Roval Alpinist CLX III apart is the total integration of performance, durability, and rider confidence. These wheels aren’t just light—they’re engineered to maintain composure under WorldTour demands, from explosive accelerations to hour-long climbs at threshold. The hooked rim profile ensures maximum tire security at high pressures, while tubeless compatibility expands ride options from ultra-supple 28mm race-day setups to wider 38mm tires for more technical roads. Every wheel is hand-built, ensuring consistent spoke tension, balanced stiffness, and long-term reliability. Roval also includes practical extras like four spare spokes, a wheel bag, and Shimano HG freehub options to make the Alpinist CLX III as versatile as it is fast. Combined with Roval’s limited lifetime warranty, these wheels represent more than just a marginal gain—they’re a holistic climbing system designed to shave every unnecessary gram, save every watt of rider effort, and deliver the confidence to attack the steepest pitches.
