Paddle Coach Bitubox

The Bitubox takes its name from Paddle Coach's tube construction and is sold with a 12K carbon face. It sits alongside the Airbox and the Tritubox as a frame in its own right rather than as a tier within a family, so the construction word is the identifying feature rather than a level. One Bitubox listing is in circulation. Paddle Coach does not publish a full specification for the frame, so the individual listing is the best guide to its balance and feel.
