Columbus Adjustment Sleeve for Trittico Stem / Alu (-5°)

A proprietary feature developed internally by Columbus. This sleeve works with standard 1-1/8” spacers, offering superior functionality in the form of three micro bike position tuning variants that allow the user to perfect their fit of their bicycle. Switching from one sleeve to the other, the rider can adjust the original geometry of the stem (position 0) adding extra length (+5mm) or a steeper angulation (-5°) to improve body-fit, handling and aerodynamic position.
