The Aerostem was designed to form a coherent whole with the bicycle and deliver high aerodynamic performance, while facilitating adjustment, rigidity and precision of the handlebars.
Its sleek design conceals a unique clamping system without front cover. It is replaced by a very strong and lightweight collar showing no growth, which allows for optimal air flow.
Its clamping system on the pivot allows a tilt of the stem to vary the height of the handlebar by 75 mm with only one spacer. This avoids adding many spacers which decreases the lateral stiffness of the bicycle and steering accuracy. The adjusting range of the Aerostem varies from -13Â° to 17Â° and is available in 6 different lengths to ensure a perfect adjustment.
In application of our Direct Drive concept, namely the optimization of the steering through a shorter pivot, oversized bearings and a rigid stem, steering is extremely accurate.
