Designed to fit 1 1/8″ threaded forks, the Stem Quill Twist SDS offers an easy-to-use twist function as well as SDS. The stem angle is adjustable between -20° and +60°, which together with the height adjustability of 8cm, allows an optimal individual seating position. The tool-free twist function allows a space-saving parking position of the handlebar in seconds. When turning back the handlebars, the stem engages again in the direction of travel. The SDS system allows the mounting of a variety of accessories easily and securely directly on the stem.
