In order to allow saddle bag mounting on dropper posts, the Wolf Tooth Valais 25 mounts to the seatpost upper, providing a secure mounting point while protecting the stanchion from wear and the wiper seal from damage.  Injection molded from an engineering-grade thermoplastic, the Valais 25 can also serve as a temporary crutch in the event of a backcountry dropper failure.  The dual-lip design securely holds packs with straps up to 25mm wide and at full compression the deep skirt contacts the seal collar first, protecting delicate seals from damage.
