The Profile Design Svet Zero Carbon Base Bar is made from multi-direction, multi-layer carbon fiber for light weight, strength and ride quality. The "Zero" portion of the name refers to its zero drop from center of clamp to center of outer extensions. In case you ever do a pro race it maintains a 3:1 ration in the wing section making it UCI compliant. Ergonomic straight brake extensions are comfortable with performance in mind. The Svet is pre-slotted for internal cable routing and Di2 compatible.
