Bib shorts were originally designed for a smoother, seamless fit at the waist, but S-Phyre bib shorts smooth out the entire fit across the thigh as well. The fabric is precision-knitted for compression, ventilation and moisture management. A completely new S-Phyre chamois has been developed for 2017. Its articulated rear section allows a freer range of motion and decreased power required to turn over the pedals. Graphics are knitted in, rather than applied, printed or sublimated. That means no hot spots. No compromise in compression. Nothing that gets in the way of fast.
