A like-for-like replacement of the stock S5 Carbon V Stem on the Cervelo S5 Aero Road Bike 2019, this superb genuine part will help you find the perfect position on the bike. The lightweight and incredibly stiff carbon fibre construction transfers all of your sprinting energy through the bike once paired with the Cervelo S5 Carbon Handlebar. The V-shaped profile is a result of Cervelo's restless aerodynamic research and has fantastic wind-cheating properties to help you slice through the air with ease.
