Jet RCD Black Disc Rear Wheel
When racing against time, the Jet RCD Black disc wheel has been the go-to rear wheel choice for the fastest TT riders and triathletes for around a decade. Handbuilt in HED’s Minnesota based facility, the “skeletal” construction sees a regular spoked wheel shrouded with irregularly profiled carbon sides. This format helps the Jet RCD realise the lowest possible drag across all yaw angles but builds in a natural amount of energy-saving vertical compliance.
The aluminium rim section integrates Turbine technology that anodises and texturises the braking surface to reduce stopping distances by up to 70% in the wet compared to all-carbon clincher disc wheels. Additionally, the aluminium rim sports a broad, 21mm wide internal measurement to better support tyre sidewalls, lowering rolling resistance and allowing comfort-inducing lower inflation pressures to be used. Tubeless-ready or standard clincher tyres are supported, giving speed-obsessed riders the most extensive choice of tyres possible.

The anodised surface on Black wheels is a formulation that is harder than the cosmetic coating on many anodised aluminium rims.
With some forethought and minimal maintenance on the rider’s part it will last a long time so please take note of the following points:
1) Use of clean rubber brake pads will result in the longest life of the black surface.
2) Embedded rocks and road grit will wear the anodising much faster than rubber brake compound. Be advised that wet and/or dirty road surfaces will contaminate brake pads. The road grit in badly contaminated pads will wear the black surface.
3) If your rides are regularly on wet and/or dirty roads the hard anodised surface on the Black rims will have a shorter life than it would in dry conditions.
