Ridley's flagship bike has a top-level carbon frame, streamlined shape and pro-level components. A sprinters dream, it's built with wind-cheating droplet-shaped tubes and an aerodynamic coating that drops wind resistance by about 4%. To make it even slicker, the carbon fork reduces drag by another 7.4%. If that doesn’t get your heart pounding, a Shimano Dura Ace drivetrain is built for speed and efficiency and your power gets to the road through Zipp ultralight 60 wheels that keep the Noah SL 20 feeling agile and aerodynamic.

  • 60 to 30 ton high-modulus unidirectional carbon frame is built from the ground up, using a blend of differing strength carbon fibres. Higher ton ratings indicate stronger carbon and a stiffer, lighter frame.
  • F-surface technology strategically places textured surfacing in areas where the air slips off the frame, to smooth overall airflow and reduce drag by approximately 4.1%.
  • Droplet shaped, aero-optimizing tubes to make it easier for the airstream to closely follow the profile of the bike.
  • Shimano Dura Ace drivetrain delivers smooth power transfer from rider to road to make an exceptionally efficient ride.
  • Splits in the F-split fork act as aerofoils and help to pull air away from the wheels (and spokes) reducing turbulence and drag.
  • Oversized tapered headtube increases the contact area of the lower headset bearing to add rigidity and dissipate vibrations.
  • Seatpost clamp is hidden to reduce drag.
  • Internal cable routing is clean, aero, and compatible with mechanical and electronic shifting. Mechanical cable stopper can be removed for conversion to electronic shifting.
  • Pressfit 30 bottom bracket allows the use of wider down tube and bottom bracket shell, providing maximum power output.
  • Pedals sold separately.
  • 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 a year after purchase.
  • Ridley was born in Flanders, Belgium, a region infamous for harsh cycling conditions. Against this backdrop Ridley engineers, tests, and refines their frame construction, race technology, tube profiles, and their own branded component line, 4ZA.
