Sitting close to the saddle hiding in the rider's draft allows for clean aerodynamics and easy access.

No more unexpected shifting due to use of zip ties. The Delta 400 is made out of aircraft alloy material, so the mount is sturdy and will not sway, allowing for fast, safe access to your bottle.

The cage design is funnel shaped allowing for easy insertion of your bottle. After inserting your bottle, the cage grips the bottle with 14lbs of tested grip force to prevent slipage.

The hardware used in the Delta 400 has Loctite and locknuts, locking the bolts in place.
