Speedfil Z4 Aerodynamic Bottle Cage (Made in USA) – Integrated Bike Computer Mount for TT / Triathlon

1. Product Overview

The Speedfil Z4 Cage is a premium bottle cage specially designed for Time Trial (TT) and Triathlon bikes. Featuring an optimized BTA (Between-The-Arms) design that fits neatly between the aerobars, it minimizes aerodynamic drag while helping you maintain an optimal aero tuck position during competition.

2. Key Features

• Authentic Made in USA: Researched, patented, and manufactured directly in the United States.

• Integrated Computer Mount: Comes with a built-in top mount designed for standard quarter-turn mounts (such as Garmin Quarter-Turn and compatible models), allowing you to keep track of your speed, heart rate, and cadence directly in your line of sight without having to lift your head.

• Premium Nylon Construction: Molded from ultra-durable Nylon 66 super-toughened composite, offering exceptional impact resistance and a secure bottle grip to prevent ejections at high speeds.

• Flexible Direct Mounting: Smart multi-slot design allows for direct and easy mounting onto TT aerobars using zip ties (included) or standard cage bolts—no bulky adapter brackets required.

• High Compatibility: Accommodates standard sports water bottles as well as the Speedfil A2 aerodynamic hydration system.
