Speedfil A2 + Speedfil Z4+ = complete BTA (between-the-arms) hydration solution for serious triathletes. The patented SpeedfilTM A2 system works with any Specialized thread compatible water bottle in both 21 fl oz. (621 ml) and 24 fl oz. (710 ml) sizes. The wind tunnel developed A2 is designed to be used with triathlon/TT aerobars. The A2 achieves its superior aerodynamics by it's key location within the riders cockpit. The athlete's arms shield the device, thus becoming invisible to the wind. The patented ZerosplashTM technology virtually eliminates fluid splashing so wet and sticky handlebars are a thing of the past. The design allows for rapid refilling on the fly, hands free drinking and easy cleaning. The Z4+ is specifically designed to be used in conjunction with the Speedfil A2. This package includes a non-slip strap that locks your A2 in place and prevents the system from rotating. Also included is a uniquely designed tube clip that secures the drink tube to the side of the bottle and completely out of the wind. This provides the rider with a greater aerodynamic advantage compared to other systems with a fixed mast. The Speedfil Z4 Cage is designed with numerous ports for a direct BTA mount into the aerobar extensions with a minimum of 4 nylon zip/cable ties. No additional mount or hardware is required. The Speedfil can be mounted in either a forward or reverse direction depending on rider preference and cockpit configuration. Garmin Integration. The Speedfil Z4 integrates a detachable arm which can hold a Garmin Quarter Turn Bike Mount* to the top of the cage when used in a BTA configuration. This not only saves precious space within the aerobars but also provides easy access. Data is now where it should be - easily viewable and easily accessible..
