Looking for additional rear storage? XLAB offers two options that are designed to complement our DELTA 425 and DELTA 425 XT carriers. The AERO POUCH 300 storage bag and the MULTI-STRIKE REPAIR HOLDER. When using these accessories please follow the recommendations below.
- Due to the extra weight demands that these systems place on the DELTA 425 and 425 XT, we only recommend installing one of these storage options at a time.
- Additionally, installing the AERO POUCH 300 onto the DELTA 425 XT will add an additional 2-3 lb of bottle retention, making it extremely difficult to remove the bottle. We don't recommend using the AERO POUCH 300 with the GORILLA XT Cage.

Instructions
Saves time
Saves 102-129 seconds for full distance at 20 and 30 mph.
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 DELTA.
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 favorite mix with you at all times.
