The Prologue builds on the success of the Podium and Breakaway. Our design team kept the longer length and narrower hamstring section to allow for more forward and rearward body movement. We also integrated the sloped front arms to cut down on superficial chaffing on the inner thigh. The biggest change is we added more foam and gel padding to soften the ride. Great for distance cycling and triathlon. Cr-mo rails. Available in Black or White. 270mm long and 135mm wide.
