Specialized's house brand has spent three generations refining the Terra platform, and the C III sits at the accessible end of that lineup without borrowing much of the flagship's price. The Roval Terra C III front wheel carries a carbon clincher rim with a hooked bead, a deliberate departure from the hookless trend that widens tire compatibility and eases the pressure restrictions hookless rims impose. Roval builds it around the same FlatStop protection found on the flagship Terra CLX III, using a 4.9mm bead hook that adds durability while keeping a broad range of tires on the approved list.

The rim measures 25.5mm deep with a 27mm internal width and a 38mm external width, a shape tuned to support gravel tires from 35mm to 60mm. That internal width lets a 45mm tire sit near its labeled dimension and holds the casing steady through cornering loads, which keeps handling predictable when the surface loosens. The profile prioritizes compliance and durability over outright aerodynamics, matching the intent of a wheel built for long mixed-surface days rather than flat-out speed.

A DT Swiss 370 hub anchors the build, running sealed steel cartridge bearings with a Center Lock rotor interface and an 18-tooth ratchet freehub. The 370 platform carries a long service record across road, gravel, and cross-country use, and its ratchet mechanism can be upgraded to higher tooth counts later without replacing the hub. The wheel uses a 12x100mm thru-axle, matching the standard on current gravel and road disc frames, and the freehub converts between HG, XD, and XDR configurations to accommodate drivetrain changes....
