Gemini Alsak Factor OSTRO VAM Seatpost

Gemini Alsak Factor OSTRO VAM Seatpost

The Gemini Alsak Factor OSTRO VAM Seatpost is among the lightest seatposts in the world. Designed and manufactured in Barcelona, this seatpost is made from forged carbon fiber and uses a unishell body. Featuring only premium materials to save weight, this seatpost uses titanium hardware. This keeps weight to a minimum while allowing it to be strong enough for road riding and racing. In addition, Gemini’s saddle clamp is compatible with both round and oval rails.

This Alsak seatpost is available in several options and was built specifically for the current generation OSTRO VAM. It is not compatible with the previous generation OSTRO VAM V1. You can choose from 300 mm, 350 mm and 400 mm seatpost lengths. These seatposts feature Gemini’s UD finish that is available in both gloss and matte finishes. The Alsak is also available with Gemini’s performance carbon layup. The performance carbon layup is Gemini’s stiffest option and is recommended for riders that weigh over 198 lbs up to 264 lbs.

Please note the Alsak seatpost cannot be cut and the minimum insertion depth must be followed.
