Zipp’s Vuka Clip with Alumina Evo Extensions is designed to provide all the performance and adjustability you need to go faster.

Designed with input from top bike fitters, the shape of the Vuka Alumina Evo is crafted to feel as if the rider is shaking hands with the bar. This is achieved through the use of a multi-radius bend paired with a 20mm inward roll of the bar that can be adjusted to dial in fit and achieve an ideal position. Vuka Clip offers greater pad-width adjustment including additional inboard (more narrow) pad positions. Pad-angle wedge inserts allow armrest pads to angle upward. -5° wedge -10° wedge -15° is possible when stacking the 5° and 10° wedges.

 The Vuka Clip’s 31.8mm clamp is compatible with the Zipp Vuka Alumina Base Bar and the Vuka Bull, and any other road, time trial, or triathlon bars rated to accept a clip-on.

Zipp’s Vuka Clip with Carbon Evo Extensions is designed to provide all the performance and adjustability you need to go faster. Vuka Evo extensions decrease drag by starting airflow over the body sooner while keeping the arms and wrists in a comfortable, relaxed position with its 20mm inward roll and multi-radius bend. The Vuka Evo Carbon 70mm rise extensions, which weigh 140g, go beyond the capabilities of aluminum. The end is contoured to better fit the hand, as well as transition smoothly from the back of a mechanical shifter.
