With a completely new design in 2024, we have aerodynamically updated the preferred all-around jersey for fast training and competitions during summer.

The TEMPO! TWO Jersey combines validated technical performance with the striking design of the TEMPO! series in a form-fitting cycling jersey, developed for warm conditions.

This unisex jersey is engineered to fit both men and women, crafted from technical materials that make it the perfect choice for sunny mountain rides or vibrant summer cycling races globally.

Featuring a back panel made of sun-protective fabric (UPF 50+) that also provides active cooling when it becomes wet, and a front panel constructed from mesh material, this jersey ensures your core stays cool, well-ventilated, and shielded during descends. The design is rounded out with an elastic band equipped with a silicone grip to secure the jersey in place, complemented by a full-length YKK zipper and three practical rear pockets.

In essence, donning the TEMPO! TWO Jersey means wrapping yourself in a rigorously tested, newly updated design – perfectly suited for competitions or fast training days in warm conditions, while also remaining a staple in your everyday wardrobe for summer rides.

Note: If ordering the Uno X Pro Team Jersey or Limited edition 7-Eleven Uno X Pro Team Jerseys, we recommend going up a size. The Tempo two jerseys are all race fit but the pro team is slightly tighter as this is not a replica jersey but the one made for the team.

Our development team has closely collaborated with pro athletes - including ColoQuicks, Frederik Muff - to extensively test the aerodynamic properties and optimal technical material composition of the Aero Sock. The result is that the contoured shaft of the Aero Sock provides evident advantages at several moments during a road race.

The Aero Sock is the optimal choice at speeds when drafting in a peloton - as well as at maximum speeds, reaching up to 70 km/h during a sprint. And at time trial speeds, our Best Speed materials are only marginally faster.

The shaft of the Aero Sock reduces wind resistance, making them faster than bare skin. The anatomical fit, along with a thin finishing silicone grip, ensures that the shaft stays in place. Because the fact is, a sliding shaft has a greater negative effect than if an aerodynamic sock were not used at all.

The foot of the sock features a reinforced heel zone and ventilated areas around the foot, ensuring the highest comfort. The Aero Sock is suitable for both women and men.
