One Aero Calf Guards are designed specifically for triathletes, bringing aerodynamic savings to your bike leg. Utilising the same technology as our aero socks, but unbridled by UCI rules, the increased length of Aero Calf Guards over our socks brings extra aerodynamic savings.  The One Aero Calf Sleeves outpace our previous generation of fabrics and surpass all but our top-tier Neo Collection.

Based on our One Aero Socks, This new generation of guards sees a switch from knitted fabrics to woven, which are lighter and provide greater aerodynamic savings.

The absence of material covering the foot means they are legal to wear under your wetsuit during the swim, saving you even more time in T1.

When is comes to £ per Watt savings, aero calf guards are the best value upgrade you can make in all of triathlon: delivering greater drag reduction than a top-of-the-line aero wheelset, for less than 1% of the price.
