Wolf Tooth Valais
Note: The DropperBlock and Wolf Tooth Valais are not compatible with our Ripsey V2 seat bag. You'll need a Ripsey V2 shim set instead.
The Wolf Tooth Valais allows you to use our Ripsey Seat Bag V1 with a dropper post. The Valais mounts to the stanchion (upper post section of a dropper post), providing a secure mounting point while protecting the stanchion from wear and the wiper seal from damage.
The Valais comes in two diameters - 25mm and 26mm. We have a list of some common dropper posts and their diameters below:

That list is current as of March 2025. If your post isn't on that list, you'll have to measure it with calipers (or take it to your local bike shop and have them do it). Make sure to measure the stanchion (upper, smaller tube of the post). And let us know the results so we can add it to our list!
If your post has a 28mm stanchion or 22mm stanchion, then you'll need our DropperBlock instead of the Valais.
