As with most things wheel related, HED proved itself an extremely early adapter when its late founder launched a disc wheel almost three decades ago. HED being HED, since that first unveiling, the Minnesota based manufacturer has been constantly tinkering with and updating the profile, structure, hub, brake track and every other aspect of the wheel. The Jet Plus Carbon Disc Wheel is the latest iteration, bringing the increased stability, comfort, and rolling speed of an expanded rim width to a wheel that HED calls the epitome of speed. The secret to the Plus build's ride quality lies in the expanded tire volume afforded by a the wider, 25mm rim. Since the tire's bead sits fatter, the tire itself follows suit, which serves to make a plusher ride with less PSI required while reducing rolling resistance by putting a healthier patch of tire on the tarmac. It also straightens the sidewalls, which means you'll also have more tire contact while cornering, a benefit that goes some way toward addressing the handling issues associated with disc wheels and TT bikes. The tire also sits more flush with the rim, creating an unbroken plane that better manages air flow across the tirewheel transition, improving yet further on the aerodynamic benefits of a disc wheel. As with every other Jet model, the Jet Disc Plus is built with a carbon fairing sandwiching 24 14 guage spokes and attached to an alloy spine. The benefits of this construction are immediately obvious to anyone who has experienced dodging carbon brake tracks when the pace is interrupted by a crash in the group or the advent of a sudden obstacle. The Jet Disc Plus' aluminum brake track grabs with more confidence and provides better modulation. It also doesn't scream under hard braking like its carbon counterpart, which both you and anyone in the vicinity will appreciate on pre work training rides on an otherwise silent, peaceful morning. The one drawback to this construction model is weight, but since disc wh...
