Easy to Drink & Refill

  • Straw

2 straw positions along with cage & mount adjustments allows for perfect straw location.

Included bite valve allows for fluid intake only, no air intake which causes bloating.

Bite valve keeps fluid at top of straw for faster drinking.

  • Refilling & Replacing Options

Solid Refill Lid is ideal for adding powder, tablets and fluid.

Slotted Refill Lid is ideal for adding tablets and fluid.

Refill area is located behind the computer allowing you to keep the computer screen clean & clear!

The TORPEDO BOTTLE can be moved to another XLAB cage on your bike so you can use standard bottles or bottles from an aid station.

Proven aerodynamically invisible by 5x WORLD CHAMPION Craig Alexander & Mat Steinmetz at the Velodrome, June 2013.

Computational Fluid Dynamic (CFD) airflow optimized and velodrome aero testing approved.

Bottle body design

Contoured design to fit your arm shape.

Small frontal area that allows a clean airflow around the bottle.

Kamm tail. Reduces drag by 50%

Airflow straighteners designed into the bottle to gather airflow for a clean, straight exit air flow.

Flush lids reduce drag.

Spacers - allows you to adjust the bottle to the height of your arms resulting in zero crosswind drag.

Dolphin tail designed straw retainer - allows you to fold the straw flat. Directs air over the straw. Saves up to 100 grams of straw drag.

Computer mounted in front of the bottle, not on top which increases aero drag.

Easy Computer Viewing

Why mount a computer behind your line of sight? The TORPEDO SYSTEM is designed to have the computer mounted in front of the bottle. Look down with your eyes and not your head!

Easier to Handle in Winds

The TORPEDO SYSTEM was designed to mount further back allowing easier steering for the rider
