Take charge of the road with full-featured performance and comfort. To make a full-featured shoe that can handle extended miles and hard roads, we started with an ultralight monofilament mesh Synchwire upper that fits and feels like a second skin, then added thermal-welded TPU for structural support and resistance to grit and grime. Fast, intuitive fit adjustment is guaranteed with dual Boa L6 buckles, steel laces, and soft lace guides that allow you to get a precise fit with even pressure distribution to ensure comfort with every turn of the pedals. And finally, the advanced carbon composite plate ensures efficient power transfer and responsive feel at the pedals, while allowing 5mm of adjustment for optimal cleat positioning.
