Cervelo ST32 Alloy Stem

Cervelo's Caledonia 5 frameset models have a proprietary D-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 design is otherwise a threadless stem in how it sets up and functions, with the Caldonia 5's split spacers, a 2-bolt steerer clamp, and 4-bolt faceplate for a 31.8mm diameter handlebar

The ST32 Stem features access for internal routing and has a rear facing section with a mild aero taper to match the Caledonia 5 frameset. Cervelo offers the ST32 in 70-130 mm lengths in a -9 degree drop.
