Profile Design Neosonic / Ergo / 45AR Bike Aerobar

Neosonic / Ergo / 45AR Aerobar

Profile Design has a long history with shorty / Draft Legal style bars. This is our latest offering and the most adjustable yet. We wanted to create a bar that would be an easy and comfortable addition to road, gravel and packing bikes. The Neosonic/Ergo platform is designed to give riders the option to move the armrests well behind the base bar in order to adopt a compact position.

Features:

• ARMREST: The Ergo armrest is an integral part of the overall adjustability scheme. The dual-offset design gives the most precise adjustment range of any armrest on the market. This, along with the evenly curved shape, allows it to work well for the majority of riders
• EXTENSIONS: With the 45AR extensions this is the most versatile Draft Legal style bar we've ever produced. This bar can be used for draft legal triathlon once shortened to meet the ITU rules
• BRACKETS: The Neosonic bracket offers our new generation fit range with a large offset to suit a range of applications
• ADJUSTABILITY: The extension length and rotation can be easily adjusted using the top bolt. There are 80 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1360 possible configurations. As a clip on bar it is also possible to adjust the extension width and tilt easily. This is the most adjustable clip on bar on the market (and in history)
