Roval Terra Aero CLX Wheelset Gravel racing, aero-first. The Roval Terra Aero CLX brings genuine aerodynamic engineering to gravel racing - a discipline where speed and tire volume once seemed like an impossible pairing. The secret is the Chopped Aero Speed rim shape: a 50mm front and 45mm rear profile that produces the drag reduction of a 70mm road wheel without the weight penalty or crosswind instability of a deep-section gravel rim, up to 5. 84 watts faster than the previous generation. Roval Aero Composite Spokes by ARRIS - titanium end pieces, aero profile - outperform round spokes by 0. 5-0. 3 watts and complete the aerodynamic picture. Wider 5. 38mm bead hooks deliver 91% more force to flat for big-tire confidence, with tubeless and insert compatibility across approved tire widths from 35 to 60mm. DT Sinc Ceramic bearings, DT Swiss Ratchet EXP engagement, UCI approval, and hand-built construction make this one of the most complete gravel wheelsets available at any price.
