The Type 5 is a legend in the triathlon world, made famous on the Ironman Kona course with multiple champions choosing it for the toughest race in the sport. A redesign of the classic JOF Fifty-Five, it’s built for forward-geometry bikes and aggressive aero positions. The narrow 55 mm nose improves thigh clearance, the deep relief channel reduces pressure on long rides, and the integrated hydration mount makes it race-ready from training to the finish line.
