Zipp Vuka Alumina EVO Extensions

We get the Zipp Vuka Alumina Extensions in our hot little hands and see if curves are back in fashion.

Anyone who has spent any time around kids knows that regardless of how old you get some of their toys still retain their allure. Lego of course is a prime example. When you are not picking it out of the shag pile, play doh is another great fun, therapeutic toy. The act of moulding play doh through your hands till it reaches that beautiful warm, malleable state can some parent’s only Zen time. What is noticeable however is that when some warm play doh is squished in your fist the shape that is left is not a simple, straight cylinder. What remains is a complex shape, something that most aero bar extensions don’t address. With an Ironman bike leg taking well in excess of 5 hours for most of us, having a comfortable bar to hold enables one to stay comfortable and aero for longer.

Anything that wears the Zipp logo has big shoes to fill. Being an industry leader in the triathlon sphere for more years than almost any of us have been in the sport carries with it a great weight. Zipps range of aero extensions have stepped up to the plate with an innovative shape to increase the comfort level of TT riders.

While the Vuka Alumina range still carries the tried and tested “ski bend” and “race bend” it is the EVO version that I have in my hot little hands. 

The EVO bars have what can best be described as a compound curve, in that they curve in two planes. The curve to the underside of the bars in the vertical plane is not earth shattering, many other bars have this feature. However the EVO bars combine this curve with what Zipp describe as “a multi-radius bend paired with a 20mm inward roll of the bar” to the horizontal plane.

This curve performs a number of functions. In the “tips in” position it allows the hands to be closer together at the tips for maximum aero advantage while still allowing the hands and wrists to stay relaxed. In the “tips out” position it allows for a super relaxed wrist and hand position for those that favour comfort over aero gains. Whichever your preference the curve of the bars allows for the bars to be rotated to accommodate personalised fine tuning. Zipp say they have designed the bar so as to feel like the rider is shaking hands with the bar, and they deserve a high 5 for their efforts.

The Vuka Alumina EVO comes in a 70mm and a 110mm rise giving even more customising options. They are both 360mm in length giving plenty of length adjustment. The 70mm and 110mm come in at 176 and 180 grams respectively and are designed to work in conjunction with Zipp’s range of Vuka base bars or being a 22.2mm diameter can be retrofitted to most bars.

Well worth a shot if you can’t make the current traditional shapes work for you or if you can’t seem to get you comfortable.
