XLab Delta 225 Rear Mount System


  • Compatible with ISM Adamo saddles with a transition hook
  • Carry your spare bottle the aero way, tucked behind you
  • Complete single bottle hydration system with mount & cage
  • Tight gripping Gorilla XT Cage keeps your bottles in place!
  • Carry your repair with the optional Multi-Strike Repair Holder

Replaces Frame Bottle

  • Standard frame-mounted bottles have high aerodynamic drag, so place your bottle at the rear instead. The Deltas are mounted on the saddle rails for no measurable drag.

Refills Front Drink System

  • Use the Deltas to refill a front drink system. Just bring the spare bottle forward from the Delta and refill. If you have the popular XLab Torpedo aerobar mounted system then simply replace the empty front bottle with the spare bottle from the Deltas.

Adds an Extra Bottle

  • These systems are also ideal for longer training rides or Century rides, where an extra bottle is necessary so you can have your favourite mix with you at all times.


  • Aerodynamic Location – Mounting to the saddle rails in the rider’s draft allows for clean aerodynamics and easy access. Great way to increase your speed.
  • Stable Design – Strong, sturdy mounting. The material used on the carrier is high strength and will not sway, allowing for fast, and safe access to the bottle.
  • Special Cage Design – The cage design is funnel shaped allowing for easy insertion of your bottle.
  • High Gripping Cage – The Gorilla XT Cage grips the bottle with 14 lbs of tested force to prevent slippage.
  • Anti-Vibration – Using Loctite and locknuts, the screws are locked in place for safety and security.
