Gravel racing has evolved past the point where road wheels with wider tires could pass as adequate equipment. The Roval Terra Aero CLX Front Wheel represents purpose-built engineering for this discipline — aerodynamic profiling developed specifically for the tire widths and speeds that define competitive gravel riding, not repurposed road shapes pressed into mixed-surface duty. The 35mm rim depth hits the performance window where aerodynamic gains remain meaningful without creating the handling instability that deeper sections introduce when crosswinds sweep across exposed terrain.

The internal width tells the real story of this wheel's intentions. At 25mm, the rim bed supports tire profiles from 35mm through 50mm with optimal casing shape — wider rubber sits naturally rather than bulging outward from a narrow foundation. This matters for cornering confidence on loose surfaces where tire contact patch and sidewall support determine how aggressively you can push through turns. The hooked tubeless design accommodates both tubeless and tubed configurations, though the wheel clearly optimizes for sealant-based setups where lower pressures unlock traction without risking pinch flats.

Roval collaborated with DT Swiss on the hub internals, using a 36-tooth Ratchet EXP driver that delivers faster engagement than the 18-tooth units found on standard DT hubs. The difference shows up when accelerating out of corners or responding to attacks — less rotational dead space between power application and wheel response. Ceramic Speed bearings reduce friction at the contact points where watts otherwise disappear into heat and resistance.... Read More
