My Serotta Ottrot, bought as a used frameset from Pro's Closet about 8 years ago, came named as OCHO. Built up with parts from my, Bianchi Infineto and added Ultegra Di2. Bontrager Carbon Iso-zone handlebars with Fizik Gel inserts have taken away all the hand fatigue for me.
I call this bike a magic carpet ride, going over little bumps that I used to feel just disappeared. I'll ride this road bike as long as I can, but make no mistake, I am the limiting factor to this bikes abilities. Andy
