Profile Design

With a rim depth of 80.5mm, Profile's Altair 80 Semi-Carbon Clinchers provide an aerodynamic advantage you're bound to notice. These wheels are more than just deep: Profile shaped the rim for optimal aerodynamics during real-world cycling conditions because they understand riding and racing isn't held in the wind tunnel. And for further aerodynamics as well as high-end strength, Profile's custom hub is laced with Sapim spokes and hidden nipples. When it's finally time to slow down, the Altairs have an aluminum braking surface for sure stopping. And, since they're clinchers, changing tires is simple.
