Alpha Q Prolite Stem

The Prolite Stem is in a league of its own, with Q-Wall Technology. Extra material is used along the sidewalls of the extension tube to increase torsional stiffness without any reduction to vertical compliance, to ensure a smooth ride over rough roads while resisting the twisting load of climbing and sprinting. 7075 alloy and an advanced 3-D forging process are used to achieve a weight of only 105 grams
