Profile Design Neosonic Ergo 45AR Aerobars | 240 mm

Neosonic/Ergo/45AR – ergonomic and highly versatile aerobars for road, gravel and triathlon bikes

The Neosonic/Ergo/45AR aerobars are designed for cyclists who want to improve their aerodynamic position by simply upgrading their road, gravel or bikepacking setup. These are among the most versatile draft-legal style aerobars – especially with the 45AR extensions, allowing adaptation to different riding styles. When shortened to meet ITU regulations, they are approved for draft-legal triathlon racing. The Neosonic brackets offer extensive adjustability, while the Ergo armrests feature a comfortable, wrist and forearm-friendly ergonomic shape that makes long-distance riding more comfortable.

Key features:

• Wide adjustability: armrest offset from -95 mm to -42.5 mm in 7.5 mm increments to suit different body positions.
• Customizable width: armrest spacing adjustable from 124 mm to 290 mm for improved stability and ergonomics.
• Height adjustment: from 59 mm to 130 mm with optional riser kits to achieve the ideal aerodynamic stack height.
