Profile Design Sonic Ergo 52a Aerobar in Black

Brand:Profile Design

Code:RHSNC521

Overview

The Sonic bracket offers an extensive fit range, low weight and easy adjustment along with minimal frontal area. Combining this withthe Ergo armrest creates an aerobar that will aid most riders in optimising their position for both speed and comfort.

The 52A is one of the newest versions of our reliable aluminium extension range.

Performance

The Sonic/Ergo is designed to present minimalfrontal area to create as little aerodynamic dragas possible. The main purpose of an aerobar is, ofcourse, to get the rider into a fast position despitea fairly minimalist appearance the Sonic/Ergo offers acomprehensive fit range for exactly this purpose.

Fit Data

The 52a extensions have a 52°for the grip. The rider can choose whether to hold high for the shrugged position or low for a more open, head up position

  • The extension length and rotation can be easilyadjusted using the top bolt.

There are 100 distinct position options achievable justby moving the armrests. Combine that with the risersand this bar offers 1500 possible configurations. Asa clip on bar it is also possible to adjust the extensionwidth and tilt easily. This is the most adjustable clip onbar on the market (and in history).

  • Armrest Offset:-70mm to -17.5mm in 7.5mm steps
  • Armrest Width:124mm to 290mm in 18.5mm steps (With Extensions at 100mm)
  • Armrest Stack:60mm (noriser kit) to130mm in 5mm increments (With aftermarketRiser Kit)

It is worth noting that our previous top level clipon aerobar, the J4/F35, offered 90 possibleconfigurations. This highlights the significant stepforward we’ve made with our new generation aerobarsin allowing riders to precisely adjust their position.

Origin

After we released the Supersonic (J5) as a premiumbracket with market leading fit options and versatilitywe wanted to bring the same kind of options to therest of our range of brackets and thus aerobars.By simplifying the extension clamp and shiftingthe wing forward to the bar centerlinewe wereable to meet our targets. As a consequence of thesimplification the Sonic is the lightest of our currentbrackets.

The Ergo armrest shares the flippable design of therest of our new generation armrests. By swappingsides or rotating the armrests smaller incrementsof movement are achieved – making it simple to finetune a riders position or match the position from theirprevious aerobar or bike.
