ST32 Stem

4 out of 5 stars
1 Review



Why We Like The ST32 Stem

Cervelo's frameset models such as the Caledonia-5, Aspero-5, and 2022 R5 feature a C-shaped steerer tube, making it so a specific stem design is required to fit the frame. The ST32 Stem fits these specific C-shape tubes, matching the frame design with a slightly aerodynamic shape and a drop of -9 degrees. The threadless ST32 Stem is constructed with alloy and designed to work with internal routing. This design must be used with the Cervelo SK-023 split spacer system and features a standard 2-bolt steer clamp and a 4-bolt handlebar clamp.
