ESF stems provide greater adaptability to your cockpit. They provide a link between the bike steerer and the handlebar that can be positioned at any angle to modify the height of the handlebar and its distance to the saddle. Available in different widths to adjust to different steerer designs the ESF1 to 4 models can also modify their length for even greater adaptability.
