Cervelo ST32 Stem

Several of Cervelo's frameset models (Caledonia-5, Aspero-5, and 2022 R5) have a proprietary C-shaped steerer tube that require a matching stem design, and the company offers this ST32 Alloy version, as well as the ST31 Carbon option. The stout but reasonably light design is otherwise a threadless stem in how it sets up and functions, with the steerer via a split spacer system and a 2-bolt steerer clamp. A 4-bolt faceplate fastens a 31.8mm diameter handlebar.
