Product Information

One step further in the search for the last percent on the bike.

What was initially a theoretical idea has been confirmed in intensive tests on the track and in the wind tunnel: the Radius Aero Calf Sleeves enable almost double-digit watt savings, depending on the shape of the calf and the speed.

The innovative fabric tube is pulled over the lower leg and is thus repeatedly perpendicular to the airstream during the pedaling cycle. The aerodynamic fabric and the special seam construction significantly reduce the air turbulence that is generated around the calf when cycling.

Due to the chosen construction and length, the Calf Sleeves can be worn under the wetsuit while swimming and thus accompany us throughout the entire competition.

  • Highly technical, aerodynamic calf sleeves
  • Proven performance gains when cycling
  • Reduction of air turbulence through fabric selection and special seam guidance
  • Suitable for triathlon and time trial (if compliant with regulations)
  • Coldblack® coating for reliable heat and UV protection
  • Secure hold thanks to silicone gripper
