Triathletes rejoice!

Rule28 Aero Guards are designed specifically for triathletes, bringing aerodynamic savings to yout bike leg. Utilising the same technology as our aero socks, but unbridled by UCI rules, the increased length of AeroGuard over our socks brings extra aerodynamic savings. 

The absence of material covering the foot also mean they are legal to wear under your wetsuit during the swim. This feature saves you even more time in T1 as it's one less thing to put on before your bike leg.

After over 2 thousand fabrics tests and many, many hours testing, we bring your our second generation of aero socks.

A proprietary design, unique to Rule 28. Our new aero socks showed aerodynamic savings of over 8W when independently tested by Silverstone Sports Engineering Hub versus our first generation model.
