452 grams for a 29-inch mountain bike front wheel represents a figure that seemed theoretical until recently. The Roval Control World Cup Front Wheel reaches that weight while meeting durability standards that allowed the Specialized Factory Racing Team to complete every race during the 2024 World Cup season without breaking a rim. That combination—featherweight construction paired with race-proven reliability—required Roval to rethink every component in the build, from carbon layup schedules to rim tape formulation, finding grams wherever physics permitted without compromising the structural integrity that technical XC courses demand.

The rim itself accounts for significant weight savings through an optimized shape that shed 44 grams compared to previous designs while exceeding durability and ride quality benchmarks. An asymmetric profile balances spoke tension more evenly across the build, addressing the inherent engineering challenge of creating a lightweight structure that won't fold under impact. The layup refinements contributed another 36 grams of savings, achieved through material placement optimization rather than simply using less material. The 28.5mm internal width supports modern XC tire volumes from 1.9" to 2.6", providing the tire profile support that traction and cornering precision require.

Vonoa carbon spokes with titanium end pieces deliver the most dramatic weight reduction—101.6 grams across the complete wheelset compared to steel equivalents. The 20-spoke front build laces in a two-cross pattern on both sides, prioritizing the lateral stiffness that determines steering precision on technical singletrack. The reduced spoke count compared to traditional builds contributes to the weight target while the carbon construction maintains the structural requirements that off-road racing imposes.... Read More
