The new Sonic bracket has been designed as the successor to the J2, which has been a somewhat ignored part of Profile Design's range. With this update it brings a new generation fit range to a wider range of price points, replacing the J2 bracket. The Ergo armrest has been created to offer both a huge upgrade in fit range as well as increased rider comfort with a supportive curve to cup the arms.
Performance
The Sonic/Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible. The main purpose of an aerobar is, of course, to get the rider into a fast position despite a fairly minimalist appearance the Sonic/Ergo offers a comprehensive fit range for exactly this purpose.
Fit Data
Armrest Offset: -70mm to -2.5mm in 7.5mm steps
Armrest Width: 124mm to 290mm in 18.5mm steps (With Extensions at 100mm)
Armrest Stack: 60mm to 70mm in 5mm increments (With aftermarket Riser Kit)
The extension length and rotation can be easily adjusted using the top bolt.
There are 100 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1500 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).
It is worth noting that the previous top-level clip-on aerobar, the J4/F35, offered 90 possible configurations. This highlights the significant step forward they’ve made with their new generation aero bars in allowing riders to precisely adjust their position.
Origin
After Profile Design released the Supersonic (J5) as a premium bracket with market leading fit options and versatility they wanted to bring the same kind of options to the rest of the range of brackets and thus aero bars. By simplifying the extension clamp and shifting the wing forward to the bar centreline Profile Design were able to meet their targets. As a consequence of the simplification, the Sonic is the lightest of the current brackets.
The Ergo armrest shares the flippable design of the rest of the new generation armrests. By swapping sides or rotating the armrests smaller increments of movement are achieved – making it simple to fine-tune a rider's position or match the position from their previous aerobar or bike.
Extensions
The 4525a extensions have the first section at 45° and the grip at 25°. The rider can choose whether to hold high for the shrugged position or low for a more open, head up position.
The 4525a offer a 7.5mm lateral shift per side. This allows the rider to get their hands narrower or wider without tilting the extensions so much that the shifters touch.
