Description

Fast as a viper.

Profile Design won't be the first to flaunt it, but it basically invented the aerobar more than two decades ago. Perhaps that's why it remains so far ahead of the curve in terms of pairing aerodynamic design with rider comfort? However, regardless of its journey, Profile Design continues to push the boundaries of aerobars, as is demonstrated with its T1+ Viper Aerobar Clip-On Bars. These bars have been selected as the official aerobar of the Ironman Triathlon, and given that they include a carbon fiber construction and Profile's brand new F-35 armrests and J4 brackets, it's easy to see why.

Profile Design constructed the T1+ Viper bars from a unidirectional carbon fiber. Why unidirectional? Well, compared to a woven carbon fiber, unidirectional carbon is oriented as it sounds, with one direction, or on one axis. And while this makes the production process more complicated in regards to load path and force direction determination, the payout is worth it to Profile. You see, compared to woven layups, unidirectional fibers provide higher levels of rigidity, while also improving the characteristic of vibration dampening. And incredibly, this is achieved at a much lower overall weight. In terms of shape, the Viper bars use an anatomic ski-bend with 0mm of drop in order to minimize discomfort at the wrist.

The handlebar clamps, made from forged 6061-T6 aluminum, tighten to the bars separately from the extensions. These clamps are separate from the armrests, so you're able to first determine the width that you're comfortable riding with. Afterwards, you set the length of the extensions, and then adjust the armrests to your desired position. And since the armrest clamp is round and clamps onto a round tube, you're able to adjust the cant of the armrests. Essentially, this provides some height adjustment, while also allowing you the opportunity to have the armrests tilted either inward or outward. For those who prefer a narrow position, having the armrests tilted upward toward the stem provides a secure feeling. And for those who like a wider position, we recommend lowering the armrests and tilting them outward. This way, it's easier to move in and out of the armrests. The armrest clamps, known as J4 brackets, are also able to be moved fore and aft on the extensions themselves.

J4 brackets allow you to set the 16mm-thick F-35 anatomic armrests at two different widths, as well as to adjust the angle of the rests and to set three fore and aft positions. People who prefer a wider position often like to rotate the rests so that they're cradling and guiding their forearm in the direction of the extension. The J4 iteration of brackets is Profile's latest foray into adjustability mastery. They allow you to adjust the armrest setback 15mm from the center of the base bar, and they're even reversible in order to provide a forward armrest position. Additionally, they're compatible with aftermarket risers should you choose to elevate your armrest position.

The Profile Design T1+ Viper Aerobar Clip-On Bars are available in the color Black and in one size. Please note that the T1+ is compatible with both 26.0 and 31.8mm clamp diameter base bars.

Fantastic fit, if not the sexiest bar

Profile Design aero bars are some of the most versatile handlebars out there. They offer a wide range of adjustment, and are easy to install on most basebars. A nice bonus of this adjustment is that they work well for the occasional road-bike-turned-tt-machine if you are looking for an aero position on your road bike. The only thing holding back the 5th star in my opinion is the Ironman branding, but there are certainly worse logo's out there.
