Take-Off Item: This product is sold as a take-off item. It was removed from a bicycle prior to use. Original packaging may be missing or incomplete. Minor cosmetic blemishes may be present. The product is in full functioning order.
The Cervélo ST31 stem is built from carbon fibre and set at an 8 degree rise, pairing a stiff front end with a finished look. An integrated top cap keeps the head tube area tidy, while internal routing channels Di2 wiring cleanly from the bar to the frame. This example measures 110mm.
This stem fits Cervélo models with D-shaped steerers, including the Áspero-5, Caledonia-5, R5, and R5-CX, giving riders a direct replacement or upgrade option for those frames. The matched geometry keeps handling consistent with Cervélo's original cockpit setup, supporting a cohesive front end across compatible road and gravel builds.
