The Reynolds Attack is their lightest and shallowest wheel in their performance line. Its 1365 gram weight smashes the 1400 gram barrier and makes the Attack a perfect choice for hill climbs or for those who like to challenge the UCI weight limit. Riders weary of crosswinds will still get some aero benefit of a 29mm cross section without getting blown around when the breeze picks up.

Lighter, stiffer, and faster than the previous Attack model, aerodynamics have also been optimized through Computational Fluid Dynamics to maximize all aero benefit from the 29mm rim section. To build the Attack rim Reynolds sources aerospace-quality carbon fiber from Japan, developed specifically to Reynolds specifications. The engineers employ their PR3 methodology, precisely assigning different carbon fiber lay-ups to three distinct regions of the rim. Each lay-up (fiber, resin, and epoxy) is optimized for the specific requirements of that area. For example, the strength requirement of the rim hook bead is much different from the rim shell profile, but the brake track has it's own needs. As such these areas have different construction. Reynolds considerable experience in cycling and working with carbon composites inform these decisions, just as it has in developing the CTg Braking System.

CTg is an acronym for Cryogenic Glass Transition and is comprised of very specific carbon and resin combinations to help dissipate heat at the exterior of the rim surface to enhance braking performance. Testing shows this reduces heat buildup by 53%, which keeps the inside of the rim much cooler than the exterior, essential for performance and safety. Proprietary Cryo-Blue Power brake pads are included with the wheelset and work in conjunction with the brake track to deliver the powerful, consistent braking while keeping things cool as you descend at speed after a long climb. ...
