- D2 Helmets
- Formula 1-like aerodynamics and ingenious technical features put the D2 helmets among the most advanced helmets in all of bicycle racing. Engineered for the dramatically different disciplines of mountain bike, downhill, BMX boarder-X and other extreme bike sports, the highly protective and stylish D2 is also worn into battle by many NASCAR pit crews including the championship-caliber #24 Team DuPont, and #20 Team Home Depot outfits.
- All D2 helmets are created by using aerospace technology. A multi-layer construction process, pre-preg materials and a high pressure curing technology are all called into action to create the industry's premier helmet.
- The D2's flow-through ventilation system inicludes four intake and exhaust ports that work in unison to maximize cool air transfer over the rider's head. A fully interchangeable, washable, MX-style padded liner as well as a D-ring strapping system combine to create a plush, custom fit. D2 helmets meet or exceed safety approval rating requirements from CSPC, ASTM (BMX and downhill), and DE.
