Shave grams without giving up control. The PRO Vibe Carbon seatpost pairs a lightweight unidirectional carbon shaft with a precision alloy head, delivering road-smoothing compliance over rough surfaces and a rock-solid platform when you're out of the saddle. At 199g for the 27.2mm version, it's a tangible weight saving that won't compromise fit flexibility.

Highlights

• Carbon shaft: reduces weight to 199g and softens road vibration for fresher legs on long rides.
• Flippable alloy head: run 0mm offset for a neutral position or flip to 15mm setback — one post, two fit options.
• Two-bolt clamp: delivers a secure, repeatable saddle angle with fine adjustment that stays put ride after ride.
• Broad rail compatibility: grips both 7×7 alloy and 7×9 carbon saddle rails without damaging lightweight carbon rails.
• Di2 ready: round shaft profile allows seamless internal routing of a Shimano Di2 battery for a clean cockpit.

Light carbon, real-world comfort

The carbon construction holds weight down and takes the edge off chip-seal and broken bitumen, so you stay fresher over distance while transferring power efficiently to the cranks. The unidirectional carbon layup keeps the shaft stiff on the lateral plane while adding just enough vertical flex to filter out fine road buzz.

One post, two positions

The flippable alloy head means you're not locked into a single saddle position. Set it in-line for 0mm offset if your fit is neutral, or flip it for 15mm of setback to dial in fore-aft saddle position — without buying a second post. It's a straightforward fit tool that suits a wide range of riding positions and frame geometries.

Compatibility & Fit

This is the 27.2mm diameter, 350mm length version with 0 or 15mm adjustable offset. It is compatible with saddles featuring round 7×7 alloy or 7×9 carbon rails. The round shaft profile accommodates internal Shimano Di2 battery integration. Confirm your frame's seat tube accepts a 27.2mm post before ordering.
