Jet RC9 Black Wheelset
Back in stock: Monday 18th July 2022
Without question, the Jet RC9 Black wheels are the fastest rim brake option when chasing a PB or a podium in target time trials and triathlons. The 90mm deep rim profile comprises a carbon skin tuned via HED’s aerodynamic patent to guarantee the lowest possible drag and highest conceivable crosswind stability when hammering along at maximum effort. The carbon skin is expertly bonded to an aluminium rim section, improving safety and control on rougher roads and when braking heavily on technical descents. Additionally, the braking surface is black anodised and textured to reduce stopping distances by up to 70% in the wet, without risking overheating and tyre blowouts sometimes seen on all carbon clincher rim brake wheels.
With speed at the forefront of its design, the Jet RC9 Black has a 21mm internal rim width to afford additional tyre sidewall support. This extra support helps tyres realise lower rolling resistance and improved impact resilience when using energy-saving lower inflation pressures. The hooked inner rim format supports tubeless-ready and standard clincher tyres, granting the most fastidious riders the broadest choice of tyres.
Sonic Pro hubs integrate silky smooth bearings, and the 5-pawl, 45-ratchet freehub gives near-instant engagement under acceleration. Sapim CX-Ray spokes complete the build, with their bladed profile further reducing drag.

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.
