Resin Transfer Molding changed what Roval could achieve at this price point. The automated RTM process controls precisely how resin saturates the carbon layup, eliminating the inconsistencies that hand layup introduces and maximizing material strength throughout the rim structure. The Terra C wheelset uses this manufacturing approach to deliver the same 32mm depth and 25mm internal width found in Roval's flagship Terra CLX and CL models, but at a cost that makes carbon gravel wheels accessible to riders who would otherwise settle for aluminum. The durability focus shows in user reports of wheels surviving crashes and impacts that would destroy lesser rims, with the RTM construction providing impact tolerance that matches or exceeds hand-laid alternatives.

The rim dimensions match the proven Terra platform that has accumulated Unbound victories and thousands of gravel miles across the product line. That 25mm internal channel supports tire widths from 28mm all-road rubber through 47mm gravel treads, with the tubeless-compatible hooked bead construction holding air reliably across that range. Pressure limits scale with tire width: 80psi maximum for narrow 28-32mm setups, dropping to 65psi for mid-range 33-36mm tires and 60psi for the widest 37-47mm rubber. The 30mm external width creates smooth aerodynamic transitions regardless of tire choice, and the moderate 32mm depth keeps weight in check while providing enough structure for lateral stiffness under cornering loads.

DT Swiss 370 hubs anchor the build with Ratchet LN internals providing 18-tooth engagement at 20 degrees of pickup. The engagement isn't as immediate as higher-tier DT Swiss options, but the mechanism delivers proven reliability and field serviceability that matters more on remote gravel routes than fractional engagement improvements. Sealed steel cartridge bearings handle the load path with the durability that harsh conditions demand, and the ratchet system can be upgraded to higher tooth counts for riders who want finer engagement without replacing the entire hub. The freehub ships with Shimano HG 11-speed compatibility but converts to XD, XDR, or HG road configurations through a simple swap, accommodating drivetrain changes without wheel replacement....
