Why We Like The ST31 Carbon Stem
The ST31 Carbon Stem is compatible with Cervelo´s renowned Caledonia 5 and features a clean, sleek design for aerodynamic gains. This stem is designed with the same top-tier carbon we´ve come to be familiar with when it comes to Cervelo, and it offers a super-stiff hold and lightweight construction. It fully integrates with Di2 wiring and the faceplate works with Cervelo´s BarFly system for easy mounting.
