Ridley Noah SL40 Disc Road Bicycle - Unisex


See available road bikes


A new benchmark in all-around race performance, Ridley's futuristic aero bike continues to innovate with the Noah SL40 Disc. While disc brakes have been gradually making their way onto road bikes over the past couple of years, the Noah Disc sits at the forefront of the aero disc revolution. Like the Noahs that came before it, the Noah Disc draws on a hyper-aero design to drastically reduce drag and save watts. Tirelessly tested, the Noah Disc has been optimized to accommodate the specific forces placed on a frame with disc brakes. For added aero benefit and responsive performance, DT Swiss R32 wheels are light, low-profile performers that boost the Noah's aerodynamic advantage. Outside of that, expect this whip to deliver rock-solid components on every level: an Ultegra groupset, Shimano hydraulic disc brakes, and a host of 4ZA components tie this beauty build together.

  • Wind-tunnel-tested carbon-fibre frame is super aerodynamic, stiff and light
  • Droplet shaped tubes and F-Surface coating increases laminar flow by more than 4%
  • Carbon layup in rear triangle and fork accommodates forces produced by disc brakes
  • F-Split carbon-fibre fork has vertical cut outs which pull wind away from wheels to reduce drag
  • 12mm thru axles increase stiffness and guarantee straight wheel installations every time
  • Performance-oriented fit is aero while still comfortable
  • Tapered head tube shaves grams while boosting stiffness
  • Lowered seat stays aid aerodynamics and acceleration
  • Internal routing of cables and hydraulic hoses reduce drag
  • DT Swiss R32 Spline Disc wheelset is aero, durable and tubeless compatible
  • Continental Ultra Sport II 25mm tires are stellar all-arounders
  • Shimano 11-speed Ultegra groupset
  • Shimano Ultegra double crank is 52-36T
  • Shimano hydraulic disc brakes represent the absolute best in braking power, modulation and control
  • 4ZA Cirrus seat post, stem and other components are light and stiff
  • Bikes are covered by MEC's Rocksolid Guarantee and Bike Service Agreement. You can bring your bike to any MEC bike shop for free adjustments and minor maintenance for up to one year after purchase
  • Ridley was born in Flanders, Belgium, a region infamous for harsh cycling conditions. Against this backdrop, Ridley engineers test and refine their frame construction, race technology, tube profiles, and their own branded component line, 4ZA
