Ridley Noah SL20 Road Bicycle - Unisex
Stiff, TDF stage-winner, smooth, sexy, light, ridiculously fast. The Noah SL20 is a lot of things, but slow isn't one of them. At the heart of the Noah SL20 is a carbon fibre frame designed to slice through the air. Aero tubes and a cut-out fork reduce drag, but it's next-level details that make the difference between fast and blistering fast. A dimpled surface on the frame significantly reduces overall drag. An F-Split fork pulls air away from the wheel, and dropped seatstays decreased exposure. An aero bike is nothing without fast wheels. Deep dish 4ZA Cirrus Pro wheels are at home rallying crit corners or establishing KOMs. To match one of the fastest frames in the world, the SL20 features 11-speed Shimano Dura-Ace, the standard for shifting perfection, braking brilliance and lightweight durability. For durability and stiffness, aluminum Cirrus Pro components won't get flexy when sprinting hard and channeling your inner-Greipel. To put it simply, Ridley made the Noah one of the fastest bikes on the planet, then made it faster.

How to measure
- Standover (J)
- Distance from the ground surface to the top of the top tube. Measured at the mid-point of the top tube, or where the rider would be standing when straddling the bike. This measurement should be 2-3cm shorter than your inseam.
