Product ID: PRSSS04XX

The Pro Vibe -17 Degree Alloy Stem, with internal routing for Di2 cables, is light, stiff, aerodynamic and perfectly aligns your cockpit for optimal control and ride position in race situations.

The integrated topcap and reversed bolts have been rigorously tested to ensure that performance also reduces air turbulence so that you will go faster without flex disrupting your power output. The stem is compatible with a 31.8mm handlebar diameter and 1-1/8" steerers.

Pro Vibe 31.8mm -17 Degrees 1-1/8" Alloy Stem

Constructed from 3D forged 7075-T6 alloy, the lightweight and strong Pro Vibe -17 Degree Alloy Stem, as used by elite riders, is high performance and race-engineered to fit 1-1/8" steerer tubes. Under the extreme strain of a high octane race situation, the gapless headlock clamp design and oversized 31.8mm diameter makes side movement under load impossible, so that no effort is wasted to unwanted flex when you are powering out of the saddle.

All elements of the design, such as the wide bolt spacing and forged alloy faceplate, are tailored for stiffness and security so that when the time comes to apply full force, whether breaking away up a climb or sprinting for the line, you can have confidence in handling the front end of the bike. Furthermore, the angled reverse bolts make maintenance easy whilst also contributing to an aerodynamic benefit.
