Show Description

Really fast, really light and just utterly beautiful. Ridley analyzed every nuance of the Helium to see where excess could be removed and strength could be added. The result is a high-modulus carbon fibre frame that weighs in at less than 1kg. It gives you stiffness to stomp to a sprint finish and the lightness that sails over the loftiest peak. A pressfit bottom bracket optimizes your output, and ultra-thin seatstays increase lateral stiffness and vertical flex. Rounded shaping is used on the seat, top, and down tubes, offering the best stiffness-to-weight ratio with the least amount of material. An oversized, tapered headtube reduces weight and increases stiffness on the front end for heightened steering precision. Superior Shimano® Ultegra components and a Di2 11-speed drivetrain offers shifting speed and precision that was unimaginable even a few years ago.

  • Frame uses high-grade carbon, 24 to 30-ton unidirectional high-modulus carbon fibre, to substantially lighten the frame. An unpainted size medium weighs in at less than 1kg (880g).
  • Ultra-thin seatstays enhance your comfort with shock-absorbing vertical flex, balanced with lateral stiffness.
  • Brakes and cassette are top-quality Ultegra components.
  • Shimano Ultegra Di2 11-speed drivetrain allows precise fast shifting and smooth power transfer from the rider to the road.
  • Cable routing is clean, aero, and compatible with mechanical and electronic shifting.
  • Pressfit 30 bottom bracket allows the use of wider down tube and bottom bracket shell, providing maximum power output.
  • Agile, aero Fulcrum Racing Quattro wheelset is hand-assembled by the Fulcrum techs and electronically tested to ensure reliability and outstanding performance.
  • This model is not equipped with pedals.
  • 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.
