The handlebar with 31.80 mm diameter does not fit on the Canyon H36 Aerocockpit, as this is an integrated carbon barstem system and does not use a separate handlebar clamp with a standard diameter. The H36 is a specially developed, integrated Cockpit in which the handlebars and stem form a single unit and are not interchangeable. Therefore, handlebars with a 31.80 mm clamping dimension are not compatible.
