Lightweight Debuts Fernweg Aero Wheelset – Maximum Aerodynamics, Minimum Weight

 

Lightweight Fernweg deep section full carbon fiber aerodynamic tubular road bike wheels

Normally, when you start getting into deep section aerodynamic wheels, weights easily creep into the 1500g range and up. Lightweight, on the heels of their Meilenstein clinchers, has just announced these 1,355g tubulars .

The rims are 81mm deep, and they’re laced with 16 front/20 rear spokes and offer both Shimano/SRAM and Campagnolo freehubs. At first glance, the rims look simple, with long flat sides and a rounded leading edge at the spoke bed. Despite appearances, Lightweight says they spent considerable time in the wind tunnel with experts from the aeronautics and automotive industries to develop them. That, combined with real world testing, led them to claim the Fernwegs are the “stiffest, lightest and probably most aerodynamic aero wheelset on the planet.”

The wheels are developed mainly for triathlon, but can be used for time trials and road racing, too. The carbon spoke construction Lightweight uses not only makes these wheels stiff, it also prevents water from entering the rim. The closed system means your wheels won’t gain water weight during wet rides. Shoot through for a close up…
