Hypersonic Mk2 Calf GuardsSignature Design
£69.99
The Hypersonic Mk2 Calf Guards deliver aerodynamic performance and sleek design for triathletes looking to maximise speed on the bike.
New for 2026, the Hypersonic Mk2 Calf Guards build on the proven speed of the original with improved aerodynamics and refined construction. Sonic-welded seams create an ultra low-profile finish that reduces drag while enhancing comfort and durability.
The aerodynamic, ribbed fabric is engineered to manage airflow around the lower leg, helping reduce aerodynamic resistance at race speeds. By replacing exposed skin with advanced aero fabric, the Hypersonic Mk2 Calf Guards deliver measurable performance benefits in fast triathlon bike legs.
A refined fit ensures the guards sit perfectly smooth against the calf, eliminating wrinkles that can compromise aerodynamic performance. Low-profile silicone grippers hold everything securely in place throughout the ride.
Lightweight, breathable and comfortable, the Hypersonic Mk2 Calf Guards are designed to perform across every distance, from sprint triathlons to full-distance events.
Proudly designed and manufactured in the UK.
Available in multiple sizes for a precise, race-ready fit.
