Triathlon Aerobar Hydration Aerodynamics: BTA vs Frame Bottles CdA Testing

Hydration positioning dramatically alters bicycle aerodynamic drag coefficients (CdA).

Wind tunnel testing proves that Between-The-Arms (BTA) hydration fairings smooth airflow between forearms, reducing CdA by 0.006 m² and saving 12 Watts.

Section III, IV, V & VI: BTA Anti-Splash Calibration, Race Refill SOP & Grip Force FAQ

Between-The-Arms systems eliminate aero-breaks while high-retention cages prevent bottle ejection over rough roads.

Section VII & VIII: BTA Sanitation Protocols and Aerodynamic Hydration Checklist

Denture cleaning tablets sterilize hydration bladders while rear bottle positioning preserves laminar airflow.

Section VII & VIII: BTA Sanitation Protocols and Aerodynamic Hydration Checklist

Denture cleaning tablets sterilize hydration bladders while rear bottle positioning preserves laminar airflow.

Section IX: Detailed Wind Tunnel CdA Drag Matrix

BTA and rear BTS hydration configurations reduce CdA by 0.010 m², yielding a 6:20 minute advantage over 90km.
