    Optimize for prime performance

    If your taste is more to a traditional bend aerobar, but you want the fastest, most adjustable bar available, Profile Designs Aeria T4 may just fit the bill. This full carbon aerobar is an award winning design that delights bike fitters with 8 bolts and seemingly infinitely movable arm rests and extensions. 

    The UCI 3:1 ratio rule segregated aerobars into two categories for several years: those that were compliant and good for time trialists and cyclists, and those that weren't, and were only fit for triathletes who don't fall under UCI regulations. Fitters didn't have optimal choices for athletes, and often riders were relegated to a sub-par aerodynamic position. Not only does the Aeria T2 fulfill the UCI 3:1 ratio requirement, they are shorter and more streamlined which give you better control while climbing in the bull-horns. 

    Profile Designs molded the basebar from a from high-modulus carbon fiber which provides optimal strength to weight ratio. Using this material, rather than aluminum, allowed Profile to optimize the shape to create the least amount of drag that was still compliant to UCI 3:1. If you look closer you'll see how the series of tapered points, from the center to the shoulder and then again from the brake caliper to the shoulder, form a series of airfoil-like designs that cut through the air. The bar is designed for internal cable routing and is Di2 compatible, which further lends to its clean, wind-cheating profile.

    The patent-pending J4 brackets connect to the bars in a simple fashion so that you won't struggle with not having enough hands for installation. While they champ down the extensions, they simultaneously attach to the base bar. The entire system features only 8-marine grade bolts that control the adjustment for six different points. The armrest clamps are narrower than Profile's other versions, which also minimizes the surface that comes in contact with the wind. 

    Stack height moves from 55 to 135mm making it the highest stack available of any Profile aerobar. You are easily able to move between a higher position and a lower, more aerodynamic position as your in-season flexibility improves. Adding to the ability to optimize your position are the carbon fiber armrests which are able to move from 155-203mm in width. 

    The T4 comes with traditional upsweep extensions. They are constructed from unidirectional carbon fiber and feature an extension adjustment of 200-300mm. This method of carbon fiber construction is not only more rigid than woven fabrics, it also dampens road vibration for a more comfortable ride.The bars are also compatible with all Profile carbon extensions should you wish to change your hand or forearm position later in the season. 
      
    The Profile Designs Aeria T4 is available in One size in the color Black. It fits 31.8mm clamp diameter stems and weighs 656 grams.
