SUB-7 Calf Sleeves
Save up to 15 watts.
The SUB-7 Project was one of the most significant moments in triathlon history, a challenge that pushed athletes, engineers and technologists to rethink what was possible over the full distance. It didn’t just redefine the limits of race-day performance. It changed how we think about speed.
The new SUB-7 Calf Sleeves are the fastest calf sleeves we have ever developed, taking technology first developed for the SUB7/SUB8 project and pushing it further.
Developed through extensive aerodynamic analysis, testing and refinement at the Silverstone Sports Engineering Hub and Derby Velodrome, the sleeves are designed to minimise drag and maximise speed. Compared with aero socks, the increased calf coverage creates greater aerodynamic potential, with testing showing savings of up to 15 watts.
Every detail has been considered to optimise airflow around the leg. From the selection of aerodynamic materials to the precision fit and construction, nothing is included without purpose. The result is a calf sleeve designed around one uncompromising objective: to make you faster.
This is the latest evolution of a technology born from one of the most ambitious performance projects in triathlon, refined for athletes looking to find speed wherever it exists.
