Abstract

The forward extension connects the for shaft to the handlebars. There is a blockable pivot (5, 13, 14) between the body for connecting to the fork shaft and a handlebar clamp (11), enabling the angle of the forward extension to be adjusted. The pivot is defined by two turning bearings., spaced out from each other horizontally in the direction of travel.
