Aeroforce-X II Calf Sleeves

WHO IT’S FOR 

You already ride in an aero position and race in an aero trisuit, and your lower legs are still meeting the air unmanaged. These calf sleeves are for athletes chasing marginal gains who want the whole body working with the air rather than against it, on the bike and on the run. 

• Athletes building a complete aero race setup 
• Long-course racers, where small savings compound over hours 
• Aeroforce-X II trisuit and Speedbelt owners completing the system 
• Short-course racers, where places are decided in seconds 

WHERE IT SITS IN THE RANGE 

The calf sleeves sit within the Aeroforce-X II race system at the top of the Zone3 triwear range, alongside the Aeroforce-X II Short Sleeve Trisuit and the Zone3 x Nopinz Speedbelt. 

KEY BENEFITS 

1. Aero coverage where kit runs out: The sleeves give your calves an aero profile on the bike, extending your aero setup below the hem of your trisuit. 
2. The gain carries onto the run: Nothing comes off in T2. The same coverage works through the run leg all the way to the line. 
3. Built by aero specialists: Nopinz builds aerodynamic race kit, and the same expertise behind the Speedbelt and the Aeroforce-X II trisuit shaped these sleeves. 
4. A system, not a single product: Worn with the Aeroforce-X II trisuit and the Speedbelt, the sleeves complete a race setup built to work as one.
