Already a highly evolved, super fast bar, the Brezza II is a full carbon with carbon extensions and arm-rests. The bar, extensions, arm rests and all hardware weigh in at 507 grams. Choose your own levers and stem for the optimum setup and the extensions are height and length adjustment. The arm rests are width adjustable. The 3T Brezza II Team Aerobar is one of the lightest and stiffest UCI legal aerobars on the market.
