Ride faster, farther, and in greater comfort with the advanced ergonomic support of Bontrager's inForm Hilo XXX Saddle. The Hilo features a full-length CRZ+ channel that allows you to stay in the aero position longer, rotate your hips farther forward, and unlock your power. Zone Density Padding places multi-density padding in strategic areas for optimal comfort and performance. That, along with the inForm BioDynamics, optimizes your natural movement for better efficiency. Oversize carbon rails and a carbon shell keep the weight down to race-day levels, too.
