These calf guards were develoepd in the Mercedes Wind Tunnel by Simon Smart of DRAG2ZERO. The results of riders wearing these calf guards speak for themselves!
Designed to reduce drag by manipulating the air flow around your calf these calf guards have become a necessity in time trialling and are now becoming more and more popular in triathlon too!
Sizing - 95% of riders need the Large/Extra Large, we have stock of the Small in black as well but these are really for people with very small legs!
