The BikeHard Challenger Carbon 66 is a full on aerodynamic racing wheel set for triathlon, time trial, or any application where cheating the wind is priority number one. Weighing in at a very light 1677 grams per set, its low weight is attained by using the highest quality components that can be engineered. The hubs are supremely crafted from aerospace grade aluminum as a straight pull radial laced front and straight pull radial laced non-drive side/three cross straight pull rear. The spokes are the world’s best bladed lightweight spoke that money can buy: Sapim CX-Ray’s in black (best in strength, aero qualities and light weight). The rims are manufactured from high modulus carbon fiber, milled to accept a conventional clincher tire (standard tire and tube). Advanced engineering of the rim ensures exceptional strength, stiffness, heat dissipation, and durability under load. Hand built in the United States, they are tensioned to perfect straightness and inspected to meet exacting quality control standards. The Challenger Carbon 66 is an ideal racing or training wheel that gives a huge aero advantage over any other wheel with a shorter rim depth.
