Extralite UltraPost Seatpost

Is This it? #01
In Stock Reminder

Product Description

The UltraPost is one of the lightest in the world, even besting most carbon fiber seatposts. The 7075 Aluminum shaft is butted, and shaped in different ways internally and externally in order to create flex in areas for comfort, and stiffness in others where comfort is not required. The clamp is designed to work both with standard round saddle rails, as well as ovalized carbon fiber rails, making this a versatile seatpost for the most elegant, lightweight builds of all.


Such a unique design requires specific installation instruction. Seatpost clamp bolts are to be torqued specifically to 3.5Nm. Also, each post has a specific minimum and maximum insert length due to its butted construction.

The minimum insert for the 250mm post is 70mm, while the 350mm post is 90mm, and the maximum insert for the 250mm is 100mm, while the 350mm is 200mm.
