Pro Vibe Ltd Carbon Puzzle Clamp Stem
Finding a stem that stands up to the power of pro cyclists can be difficult, but the Pro Vibe Ltd Carbon Puzzle Clamp Stem is more than up to the task. Made from unidirectional carbon fibre and a 7075-T6 alloy construction, the stem remains lightweight and stiff through every phase of your ride.
For the front clamp, Pro have integrated a gapless design. This ultimately reduces stress on the top bolts. Wide bolt spacing and a forged aluminium faceplate increase strength and rigidity even further.
Designed to reduce drag over the stem area, the integrated top cap design allows air to flow unhindered over the stem. The oversized 31.8 millimetre clamp diameter further reduces unwanted flex under high load by increasing strength and stiffness.
