Alpitude Tonale Seatpost for Factor ONE 2026
The Alpitude Tonale is a lightweight carbon seatpost developed specifically for the Factor ONE 2026.
Weighing from just 127g, it is the perfect upgrade for riders who want to remove weight from the Factor ONE without compromising its clean lines, aero profile or premium finish.
Each Tonale seatpost is handmade in Italy using premium carbon fibre, high-pressure moulding and an internal silicone bladder. This creates a precise, consistent carbon surface on both the outside and inside of the seatpost.
Built Exclusively for the Factor ONE 2026
This is not a universal aero seatpost adapted to fit multiple frames. The Tonale has been designed specifically for the 2026 Factor ONE, ensuring the correct profile and fit for the frame.
It is available with a 0mm offset and in four lengths, allowing you to choose the right fit without carrying unnecessary material or weight.
Designed for Lightweight Carbon Saddles
The Tonale uses a wider saddle-clamp contact area to distribute pressure more evenly across the saddle rails.
This helps reduce concentrated stress on carbon rails, making the Tonale an ideal partner for a premium lightweight saddle and a serious Factor ONE build.
