BikeHard Challenger Pro Asym 700c Road Wheel Set ShimanoThe BikeHard Challenger Pro Asym wheel set is the top of the line alloy wheel set in the Challenger line. The same straight pull hubs found on the Challenger Carbon wheels are mated up to welded double wall rims with extremely stiff aerodynamic bladed spokes. To decrease weight and help in all climbing efforts, the front wheel has a 26mm deep rim and 20 radial laced bladed spokes. To increase balance where it is needed underneath the rider, the 30mm deep rear rim is asymmetrically offset to moderate the angle of spokes towards the non-drive side. This asymmetrical offset to the rim ensures a more even distribution of forces to both the drive and non-drive side: 24 bladed spokes are radial laced on the non-drive side and crossed 3 times on the drive side. Weighing in at a super light 1550 grams per set, all of these weight saving technologies still do not jeopardize the strength for either front or rear: this wheel set is equally up to the task of either everyday training or hardcore racing.850228007738
