Valais 25

SHIPPING, RETURNS & PURCHASES

The Valais 25 is an adapter that allows you to use a seat bag with a dropper post. The Valais mounts on the stanchion (upper section of the post), providing a secure mounting point while protecting the stanchion from wear and the wiper seal from damage.

We offer two Valais diameters, so you’ll need to know your stanchion diameter. Valais 25 refers to the strap height that the Valais allows (25mm or 1" strap height). The dual-lip design holds bags securely with straps up to 25mm wide, and at full compression the deep skirt contacts the collar first, protecting delicate seals from damage. While the Valais is optimized for straps up to 25mm wide, it will also work with wider straps. The adapter is injection-molded from an engineering-grade thermoplastic and is strong enough to serve as a temporary emergency post in the event of a backcountry dropper failure.

Made from solid, resilient, non-stick DuPont™ Delrin® thermoplastic for easy installation and maximum strength down to -20°F / -29°C.

Small and medium saddle bags are ideal places to safely store tubes, mini tools and CO2 cartridges, ensuring they’re always within reach when needed, while freeing up your top tube and handlebar bags for items you need to access more frequently.

Protects seatposts: Affordable insurance, the Valais protects seatposts from wear that occurs where the seat bag, seatpost and tire tread intersect.

Emergency post: While dropper posts keep improving, lock mechanism failures still happen, often far from the trailhead. The Valais can be used to hold the post extended, allowing the rider to pedal comfortably out of the backcountry.

Travel limiter: When full drop is more than the terrain requires, the Valais can be used to limit dropper travel.

Requires an internally routed dropper post
Optimized for straps up to 1" (25mm) wide, but will work with wider straps
There are two Valais sizes available: one for 25mm diameter stanchions and one for 26mm stanchions. Measure the diameter of the upper seatpost stanchion to determine the correct size.
The 25mm Valais fits posts from 24.75 to 25.25mm in diameter. Some posts known to be this size include:

Easton Haven
Giant Contact (internal routing)
RaceFace Turbine
RockShox Reverb Stealth

At full compression, the deep skirt of the Valais contacts the seal collar first and does not touch the seal lip (protecting delicate seals from damage).

NOTE: You will likely lose the lowest saddle position because the Valais reduces dropper travel by 25mm.
