USE Tula Aerobars w/Carbon Extensions

The USE Tula Aerobars w/Carbon Extensions is a time trial base bar built around one goal: getting a rider into a faster, more sustainable position. The bar's profile stays within the UCI's 3:1 aerodynamic ratio for race legality, and USE built the arm rests with a "Rock & Roll" tilt adjustment so riders can dial in the exact angle that keeps their shoulders relaxed over a long TT or triathlon effort. Fizik-developed gel pads sit under the arm rests, and the brake levers mount parallel to the extensions, keeping the whole front end clean and within easy reach from the aero position.

The carbon extensions bolt on with adjustable length and reach, and come in either a straight or S-bend shape depending on how a rider prefers to hold the base bar on longer stretches. Cable routing runs internally through the bar rather than looping externally, which keeps the aero profile intact and the cockpit tidy. The bar clamps to a standard 31.8mm stem, so it drops onto most existing road or TT setups without needing a proprietary stem swap. At around 495 grams complete with levers, this aero base bar sits toward the premium end of the category, aimed at time trial and triathlon riders who want a race-ready position with real adjustability built in rather than a fixed, one-size setup.
