Show Description

Put a healthy space between you and the competition. 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 Ultegra components and a Shimano® 11-speed Di2 drivetrain creates highly efficient power transfer from the rider to the road.

  • Frame uses high-grade carbon, 30 to 24-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.
  • Full complement of top quality Ultegra components.
  • Shimano Ultegra 11-speed Di2 drivetrain allows smooth power transfer from the rider to the road.
  • 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.
  • Fulcrum Racing 5 wheelset features an oversized flange and Spoke Dynamic Balance technology, incorporating an asymmetric rear rim to increase lateral and torsional rigidity and response for a higher performance lever.
  • 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.
