The rim itself measures 35mm external width, 21mm internal width, and uses a hooked carbon clincher construction that is tubeless compatible . Roval optimized the profile around 28mm tires, though the design also accommodates 26 to 30mm tires depending on setup preference. The wider internal channel supports the trend toward higher-volume road tires that have quietly become the fastest option in rolling resistance testing, and the external width creates a smooth aerodynamic transition from tire to rim rather than a stepped junction that would spoil airflow.

Spokes are where the newest generation earns much of its weight savings. Composite spokes with titanium fittings are 2.3g lighter, 63% stronger, saving a total of 96.6g across the wheelset compared to the steel spokes on the previous generation. The 18-spoke front build laces in a two-cross/radial 2:1 pattern, not tucked, with Arris MK4 alloy nipples in 6mm length. The 2:1 pattern loads more spokes on the disc-brake side to counter the asymmetric forces that come with disc braking, keeping the wheel true under hard efforts.

Behind the rim, the wheels are built around DT Swiss 180 EXP internals housed in Roval's low-flange road hubs with ceramic SINC bearings . The front hub uses a 12x100mm thru-axle with 19mm OD end caps installed and Center Lock rotor mounting. DT Swiss 180 internals are the top of DT's road hub range, and the SINC ceramic bearings reduce friction at the hub shell to marginal but measurable levels over race distances.

FlatStop bead hook technology addresses the tire security concerns that come with hard racing. FlatStop bead hooks disperse impact and need 39% more force to flat , widening the bead contact area beyond typical hooked rim standards. For riders running latex tubes or racing on rough pavement, that added margin between rim strike and pinch flat is where race days get saved.
