The release & use of this rim has stirred plenty of debate as to its ideal application. Some call it the best TT wheel they have ridden, to others their favorite crit wheel, cyclo-crossers swear by them, & road racing is a given. Where things get really interesting is that the rim is so light that some racers insist it should even be used for hill climbs. Given this wheel's uncompromising cornering & aero performance, our pro racers report abnormal amounts of friction amongst team members as they vie for the opportunity to roll the 65s in their "A" priority races vs. other options. The cycling world may be a more harmonious place without the 65, but it certainly wouldn't be as fast. Available as: 65 Clincher, 1.65 Tubular (Ultralight), & 2.65 Tubular (Standard). After you have chosen what's best suited for your discipline, it's clear you will love the " Founders Favorite".
