The upper is made with a supportive TPU frame that’s laser welded to ultralight mesh panels. It has a low-profile collar to reduce negative torque, along with an ultra-low 6.5mm stack height that gives you a close connection to the pedals. The Energy Full SLR Outsole is also 10g lighter than our previous outsoles. Every little bit helps in the hills.
The last features a precise anatomic heel hold and a rounded toe box. It also has a heel retention system inside the structure, so there's no need for extra elements or weight to achieve a precise, personalized fit.
Usually, power transfer is all about the outsole. But we’ve created a new overlap upper that ensures every watt you produce goes straight into the pedals. It provides a snug, even fit with no pressure or hotspots. And the premium Boa IP1 closure dial gives you micro-adjustment for a precise fit and performance, plus a quick and easy release system.
