Even more rigid, direct and agile: The ergotec 35.0 handlebar systems In the sporting MTB field in particular, cyclists attach great importance to agility and minimal flexibility in their handlebars, so that they can execute steering manoeuvres on rough terrain smoothly and also master tight curves with precision. In order to meet these requirements the more exact bar bore diameter has been increased from 31.8 mm to 35.0 mm, which provides significantly more rigid and accordingly more direct steering behaviour. To round off the program there is a matching seat post in the same design as the new 35.0 handlebar system.
