Supersonic Ergo+ 35 SLC Aerobar

What Our Gearhead® Experts Are Saying:

"I like this version for riders who want a slightly lower wrist angle without going full high-hands. The 35° ski bend feels natural for long efforts, and the fit range is massive. It’s easy to micro-adjust pad width and stack, and the SLC extensions keep the setup light and clean."

When every watt counts and position is everything, the Supersonic Ergo+ 35 SLC Aerobar from Profile Design gives us the freedom to chase the perfect setup. Built around the Supersonic bracket platform, it blends expansive adjustability with lightweight carbon construction to help us stay aerodynamic and comfortable over long race efforts.

The internal wedge clamp system secures the extensions while allowing smoother, broader fit adjustments than traditional clip-ons. With 80 armrest position options—and up to 1440 total configurations when paired with Universal Riser Kits—we can dial in width, offset, and stack with precision. The extended Ergo+ armrests add 40mm of forearm support and feature textured 10mm pads to stabilize us during sustained aero riding.

The 35 SLC carbon extensions feature a 35° ski-bend profile that promotes a slightly turned-down wrist position for a streamlined hand posture. Measuring 400mm and cut-to-size, with a 22.2mm clamp diameter and rear-exit cable routing, they integrate cleanly with both mechanical and Di2 systems. At just 627g total, this aerobar offers elite-level fit control and lightweight performance for serious triathlon and time trial athletes.
