Officially a fast bar

Profile Design continues to push the boundaries of aerobars, even though it effectively invented them decades ago. The T1+ Carbon Aerobars 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 no wonder why.

Profile Design constructed the T1+ Carbon 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. Compared to woven layups, unidirectional fibers provide higher levels of rigidity, while also improving the characteristic of vibration dampening. 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. 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+ Carbon Aerobars 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.
