HUUB 3:Sixteen Calf Sleeves

Experience revolutionary aerodynamic performance with the HUB 3:Sixteen Calf Sleeves, featuring patented Aero-Bridge technology that delivers up to 12 watts of power savings. The innovative design combines smooth and ribbed fabrics to create a suspended bridge effect, disrupting airflow and enhancing boundary layer displacement for unparalleled aerodynamic advantages. These competition-legal calf guards offer the market's most cost-effective watts-per-pound investment, suitable for both cycling and triathlon events.

Developed at the prestigious Silverstone Sports Engineering Hub and Derby Velodrome, these calf sleeves earned their stripes during the historic Sub7/Sub8 challenge, contributing to Joe Skipper's remarkable 3-hour 16-minute bike split. The project brought together elite athletes including Alex Dowsett and UCI Hour Record holder Dan Bigham, whose expertise helped create this groundbreaking product that seamlessly integrates with wetsuits for complete race-day performance.
