XLab Delta 425 Rear Mount System

Sturdy, reliable storage system with stiff alloy arms. Gorilla Cage has a tight 7lb grip on bottles eliminating unexpected launches. The Delta 425 mounts to the saddle, hiding in body’s draft. You can also pair the Delta 425 with the Aero Pouch 300 or the Multi-Strike Repair Holder to carry the essential repair tools. Adjust the Delta to your personal liking as you can change the cage angle and cage height for a perfect custom position.

Lik SinIt works on my ISM PR series saddle. Took awhile to adjust everything but it works.
Rusty45678I had done a heap of research on rear mount holders and every article/review was leaning towards xlab. I can see why. The delta is bulletproof. I have fitted this to fizik tritone 5.5 saddle and it fits like dream. Gorilla cage is tight and haven't had any issues with bottles popping out. High quality construction.
Mr BerryExcellent product. Easy to mount and very flexible with regards to fitting on a variety of saddles.
