Dean Fast

Put simply, the Dean Fast is among the very fastest tri bikes on the planet. Ridley’s F-technologies create the distinct, sculpted, wind-cheating designs that can save competitors up to two minutes when riding 112 miles across the wind-swept Kona course. This is achieved partly via careful molded-in F-surface technology and all-internal cable routing – both of which create some of the cleanest laminar flows on any tri bike available, particularly in real-world riding situations. Every rider will appreciate the custom stack-and-reach, making the Dean fit everyone with the lowest possible riding position.
