Tibia is a total re-think of the stem. That humble but critical connection from the steerer to the handlebar.
Tibia sets a new benchmark in carbon fabrication; an ideal choice of fiber, following the natural principle of minimizing tension differences, makes the stem super-stiff yet forgiving to ride, with excellent damping to soak up road buzz.
Extremely lightweight at barely 80 grams (100 mm), and with a streamlined shape inspired by natural forms, Tibia provides the optimal connection between the handlebar and the front wheel. New clamping hardware in Titanium and Aluminum ensures that the carbon fibers run end-to-end without being severed by bolt thread inserts. Of course the front plate is also made of carbon, with highly sophisticated very small structural elements.
The high quality of the carbon fabrication needs only buffing to a satin polish, a finish that eliminates a clearcoat and saves extra grams. This makes the Tibia by far the stiffest and strongest stem in the lightweight crowd.
