Description The Bicycle Wheel Warehouse Pure Race Superlight wheel set draws its inspiration from an intellectual consideration of intended use and functionality. This approach differs markedly from the typical, “this is the lightest wheel set you can buy” mind set. This consideration focuses on the superlative Pure Race rim’s tapered 27mm x 19mm profile (HxW), which combined with the fact that at 430g weighs less than any Mavic clincher aluminum rim we can buy, makes this one of the best clincher options available, period. Given this rim’s impressive strength, wheel “stiffness” concerns are mitigated; your toughest decision will be to select which build level interests you most. The sealed bearing front hub is ultra light, about 71g. The rear sealed bearing cassette hub is also exceptionally light, at 241g, and features an advanced aluminum alloy hub shell, axle, and freehub design. The front wheel is built with 24 spokes that are radially laced, the rear uses 28 spokes laced three cross on both the drive and non-drive sides. In an effort to preserve lateral stiffness and overall wheel longevity, we resisted the temptation to build this wheel set with fewer spokes. We believe this combination of 24 in front and 28 for the rear wheel offers the best combination between weight savings and durability. In sum, the Pure Race wheel set is focused specifically for speed through the reduction of rotational weight at every level, but does not sacrifice practicality. The Pure Race rim offers a robust starting point to serve as a rigid platform in which to build an exceptional wheel set. Please feel free to take a closer look.
