FastTT - BTA Tower Pack 80+25mm

Raise and level your between-the-arms hydration setup with the FastTT BTA Tower Pack. Designed to position the BTA bottle horizontally between the rider’s arms, the tower helps create a cleaner hydration arrangement while its optimized aerodynamic profile helps minimize drag around the bottle area.

Available in two configurations, the tower can support either a standard single-bottle installation or a twin-stack setup with an integrated aero cone for the lower bottle.

Key Features

• Elevated BTA Position: Raises the bottle between the rider’s arms
• Horizontal Bottle Alignment: Helps maintain a level and streamlined bottle position
• Optimized Aero Profile: Designed to minimize drag around the hydration area
• Two Configuration Options: Available as a Standard Tower or with an Integrated Bottle Aero Cone
