SAVE UP TO 12 WATTS

Athletes can now benefit from the watt saving technology found in our record-breaking Aero-Bridge Undervest. Compared to aero socks, the extra calf coverage gives even greater aerodynamic and time savings. Saving up to 12 watts, these Calf Sleeves are the best investment on the market, with the highest £/watt aero gain.

DEVELOPED ALONGSIDE THE WORLD'S GREATEST 

Utilising the same technology as our Aero-Bridge Undervest, the 3:Sixteen Calf Sleeve is born. Developed at the Silverstone Sports Engineering Hub and Derby Velodrome alongside the World's greatest engineers and riders. 

The Calf Sleeves were first introduced to the sporting World during the Sub7 / Sub8 challenge, with the design and name 3:Sixteen a nod towards the 3-hour 16-minute bike leg that was achieved to help guide Joe Skipper to a sub 7-hour Ironman. The team comprised of some of the World's best time-trialists, including Alex Dowsett and recently crowned UCI Hour Record holder Dan Bigham, who crushed the opposing team to deliver one of the most incredible time trials of all time.

PATENTED AERO-BRIDGE TECHNOLOGY - HOW IT WORKS

By stretching smooth fabric over ribbed fabric (raised ridges form a suspension of material like a suspension bridge) to disrupt the airflow by the ridge and then further alter it by the suspended fabric, causing minuscule air particles to enhance displacement of the boundary layer. 

  • Up to 12 Watt saving.
  • Designed for the Sub7 Sub 8 record-breaking challenge.
  • Dan Bigham designed and enhanced.
  • Precisely patterned to maximise aero gains.
  • Aerodynamic materials.
  • TT and track proven.

For sizing, measure the widest part of the calf.

Calf guards can be worn in triathlon competition under your wetsuit and for the duration of the event.
