Zipp's Vuka Clip with Carbon Race Extensions provides a highly adjustable system allowing you to dial in your aero tuck, and stay there.
The Vuka Race Carbon Extension was designed using data compiled from thousands of fit sessions with recreational and professional cyclists and triathletes by the world's best fitters. The Vuka Race bend places the wrists at a more natural bend to help riders remain in their tuck to optimize aerodynamics.
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.

I've been racing triathlons on and off for 20 years and it came time to update my rig. A friend sold me his Specialized Tarmac Fact road bike with traditional drops. As I'm much more comfortable in aero bars, the Zipp Vuka's were a natural solution, to match the SRAM Red group set. SRAM E-TAP Clics bar end shifter make me feel lazy now,
The aero bars did require some rotation adjustment when it appeared they didn't align parallel. Just a simple turning of one bar inward fixed that.
Expensive... yes, but well worth the money. I have these on two of my bikes and have found them to be simple to install, use high quality materials, and are easily adjusted for exactly aero positioning. I've used bars and they are now collecting dust... do it right the first time and you won't be wasting your money.
