  Best in class aerodynamics at a race ready weight

  By adopting the proven rim profiles of the Artech series (without the Aeroscales) the R4.A delivers best in benchmark-tested aerodynamic performance. With steel spokes and a total weight of just 1398 grams, it is the ultimate all-round, climbing and even gravel wheelset fitting wider tires and built to excel both in the heat of competition and in the demands of daily training.

  Beyond its low weight and aerodynamic advantage, the R4 combines exceptional lateral stiffness with uncompromising durability. Its 25 mm internal width hooked rim is aerodynamically optimized for 30 mm clincher and tubeless tires, offering the perfect balance of rolling resistance, efficiency, and comfort. Meanwhile, the mechanical labyrinth system protects against dirt ingress, ensuring long-term reliability and consistent performance.

  Algorithm Enhanced Aerodynamics

  The shape of our rims is defined by our Algorithm Enhanced Aerodynamics (AEA) technology. This algorithm optimizes the most aerodynamic rim-profile guaranteeing optimal aerodynamic performance.

  Lightweight design

  With our Local Reinforcement carbon technology, we’ve increased the number of carbon layers around the spoke holes on the inside of the rim. This way we significantly reduce weight while preserving strength and stiffness.

  Perfect tire-fit

  The unique geometry of our Scope Tubeless System ensures easy mounting, direct inflation, long-lasting pressure and compatibility with all clincher and tubeless tires.

  Lightweight and durable

  The Diamond Ratchet SL system is made from titanium and finished with a diamond like carbon coating. This results in direct engagement, improved durability, and a significant reduction in weight.
