The Cobb Ironman Fifty-Five is the official Ironman bicycle seat. This new exclusive global partnership with Ironman unites the leader in innovative seat technology with the leader in Triathlon events. Now it’s possible to get a great fit, go fast, and show off the reason why you work so hard to get race ready.
The Fifty-Five is the first seat to use Cobb Cycling’s exclusive JOF or ‘Just Off Front’ geometry. It is designed to provide unparalleled comfort and performance for modern triathlon and time-trial cyclists, and it sets the benchmark in both regards. It has a short nose and long pressure relief channel to suit a fast, aggressive position.
