FastTT Big Kahuna Twin BTA Bottle Cage Kit

When aiming for top performance, every detail in the cockpit counts, including how you carry your water bottles. The Big Kahuna Twin BTA has been designed to meet this requirement: by positioning both water bottles horizontally between the arms of the holder, this kit significantly reduces the drag generated by the cockpit. Wind tunnel tests carried out at the University of Auckland confirm an average gain of 9.1 watts compared to a configuration without the BTA, an advantage that translates directly into speed over long distances.

The kit is compatible with both the mono and twin-stack FastTT adapter plates, as well as the majority of cockpits fitted with a standard thread size between 62 and 65 mm. The kit supplied includes everything you need: an integrated conical tower available in 130 mm or 80 mm depending on the desired height, an aero cone for the top bottle cage, the double-stack mount and a full set of fasteners (Nylstop bolts and nuts).
