What Our Gearhead Experts Are Saying:

"I recommend this to riders who prefer a classic ski-bend feel with modern adjustability. The 50 SLC extensions feel natural for high-hands setups, and the adjustability in pad width and stack makes dialing in position straightforward. It’s light, stiff, and ideal for serious tri or TT builds."

When we’re refining our aero position for race day, the Supersonic Ergo+ 50 SLC Aerobar from Profile Design gives us total control over fit and feel. Designed around the Supersonic bracket platform, it blends elite-level adjustability with lightweight carbon performance to help us stay powerful and aerodynamic over long efforts.

The internal wedge clamp system secures the extensions cleanly while expanding the fit range beyond traditional clip-ons. With 80 armrest position options—and up to 1440 configurations when combined with Universal Riser Kits—we can micro-adjust width, offset, and stack to match our ideal biomechanical setup. The Ergo+ armrests extend forearm support by 40mm and feature textured 10mm pads for confident stability in aggressive positions.

The 50 SLC ski-bend carbon extensions offer a 50 profile that naturally supports high-hands aerodynamic postures. A 7.5mm lateral shift per side allows subtle hand width refinement without excessive tilt, and the 400mm cut-to-size length ensures compatibility across a wide range of rider fits. With Di2 compatibility and rear-exit cable routing, this 628g system delivers clean integration and race-ready efficiency for athletes chasing every marginal gain.
