The TEMPO! PRO Calf Sleeves were developed alongside Fusion's professional athletes and race-tested at the 2025 Ironman World Championship in Nice by Magnus Ditlev, Daniel Bækkegaard and Kristian Høgenhaug.
After extensive wind tunnel cylinder testing and real-world rider validation, Fusion have created a next-generation calf sleeve featuring a broader aerodynamic profile that delivers improved performance over the original TEMPO! One Calf Sleeve.
The two-piece construction combines two premium French aerodynamic fabrics, each positioned to optimise airflow and minimise drag. A carefully engineered curved seam controls fabric tension across a wide range of calf shapes, ensuring the aerodynamic zones remain precisely aligned where they perform best.
The seam placement also serves an aerodynamic function, helping to manage airflow around the lower leg for greater efficiency at speed.
Designed for athletes riding above 40 km/h, the TEMPO! PRO Calf Sleeves are built to reduce aerodynamic drag when every watt matters. Pair them with the TEMPO! PRO Tri Suit for the complete race-day aerodynamic system.
