At 518 grams including tubeless tape and valve, the Roval Alpinist CLX III Front Wheel enters territory once reserved for tubular race-day hoops that demanded gluing skills and spare wheel support. The clincher format here accepts standard tubeless or tubed tires, making the weight figure practical for everyday climbing rides rather than just special occasions. Paired with the 613-gram rear, the complete wheelset lands at 1,131 grams—134 grams lighter than the previous Alpinist CLX generation.

The weight reduction stems largely from the Roval Aero Composite Spokes developed with ARRIS. Each spoke saves 1.9 grams versus steel while testing 20% stronger, and the 21-spoke front count means meaningful system savings. Titanium end pieces at the hub flange and rim nipple interfaces handle the stress concentration points that have historically challenged composite spoke durability. The lacing uses a 2:1 pattern with two-cross on the rotor side and radial on the opposite flange, optimizing braking load distribution while maintaining lateral stiffness.

Roval's Low Flange hub keeps rotating mass close to the axle centerline, further reducing the moment of inertia that affects acceleration feel. DT Swiss SINC ceramic bearings handle the rotation duties—the same bearing specification used across Roval's flagship road wheels. The 12x100mm thru-axle spacing and Center Lock rotor interface follow current road disc standards, ensuring broad frame compatibility.... Read More
