Hilo XXX Carbon

Supporting a traditional seating position and the ultra-efficient, out-on-the-nose aero position, the Hilo XXX saddle features a full-length CRZ+ channel that allows you to stay aero longer, rotate your hips farther forward, and unlock power you didn't even know you had. Zone Density Padding plus our groundbreaking Smart Cover deliver targeted areas of varied support for optimal comfort. Carbon rails and carbon-reinforced shell, make it the lightest, most advanced tri/TT saddle we've ever made.
