The Reynolds Attack Carbon Clincher Tubeless Wheelset is their lightest and shallowest wheel in their performance line. Its 1365 gram weight smashes the 1400 gram hurdle 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 utilizes two technology processes. First is Enhanced SLG. Lighter, stiffer, and faster than the previous version, aerodynamics have also been improved through Computational Fluid Dynamics with the Enhanced SLG, or Swirl Lip Generator. This is essentially a groove on both sides of the rim profile that drastically improves air flow, reduces drag, and assists in wheel stability. 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.

The Attack rim now uses a 17mm internal width rim channel that is Tubeless Ready. This allows the flexibility to run a tubeless clincher or a regular clincher tire with an inner tube. It has been proven that running the proper tires at slightly lower pressures is actually faster than most max pressure options. Small punctures, always the bane of the unlucky attacking cyclist, can virtually be eliminated. Overall versatility also comes from the 25mm rim width and 29mm section profile. Paired with a 23-25mm tire, the footprint is larger for exceptional grip and handling. Stability comes from the overall stiffness and wider structure. You won't be buffeted by cross winds, nor get tentative on rougher roads or in sharp corners. The Attack feels feathery light and smooth as you jump from the group or fly up the hill, and the aerodynamics help you hold speed when in the wind, or when drafting. The lateral stiffness will impress you, and the vertical compliance in a wheelset this light will surprise you .

DT Aerocomp bladed spokes are laced to Reynolds straight-pull hubs, using DT alloy nipples. The cartridge bearing hubs are which are as smooth and durable as they are simple to maintain. The front wheel's 20 spokes are radially laced at high tension for lateral stiffness and aerodynamics. The 24 rear spokes are laced 2x on the drive side and radial on the non-drive, and when tensioned on the stout 25mm rim, the response is immediate. Overall, the Attack Carbon Clincher Tubeless is an exceptional wheelset for those who prefer the lightest, most responsive wheels. As a competitor, you have to know your strengths and weaknesses. Your equipment can help you exploit the former, and overcome the latter. The Attack was developed to deliver explosive accelerations in any situation. If that is your preferred tactic, then this is the wheelset for you.
