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.

  • A stiff and light aerodynamic stem for speeding across the tarmac
  • Unidirectional carbon is stiff and durable enough for our rides
  • A contoured shape creates wind-slicing freedom and reduced drag
  • Integrated top cap prevents wind catching for a seamless fit
