Profile Design

Supersonic Ergo+ 50 SLC Aerobar

The Profile Design Supersonic Ergo+ 50 SLC Aerobar is a highly adjustable triathlon and time trial aerobar built for riders who need precise fit control without compromising stability. Its independent adjustment range makes it easier to dial in pad height, reach, and width for a sustainable aero position—whether the goal is improved comfort for long-course triathlon or a more aggressive TT setup.

Fit and position advantages that matter

• Independent adjustment range - Enables fine-tuning of reach and pad placement to hit a repeatable aero position without forcing compromises in comfort or handling
• 50° ski-bend SLC extensions - 400mm long, 22.2mm diameter extensions support a higher-hand posture many riders prefer for wrist comfort and steady control in the aerobars
• Lateral shift capability - 7.5mm lateral shift helps refine hand/extension alignment to match shoulder width and natural tracking
• Cut-to-fit + rear-exit routing - Extensions can be trimmed to length and are drilled for rear-exit cable routing for a cleaner cockpit and simpler service planning
• Ergo+ armrests with 10mm pads - Shaped arm cups and included pads provide stable forearm support for holding aero longer with less upper-body fatigue
• Broad pad position ranges - Armrest width adjusts from 124mm to 290mm in 18.5mm steps (with extensions at 100mm); armrest offset adjusts from -85mm to -17.5mm in 15mm steps; armrest stack starts at 58.5mm and is compatible with existing risers up to 138.5mm stack (with 70mm of spacers added)
