The main purpose of an aerobar is, of course, to get the rider into a fast position and, despite a fairly minimalist appearance, the Sonic Ergo offers a comprehensive fit range for exactly this purpose.

PROFILE DESIGN - SONIC ERGO 45/25A 

REPLACES T3+

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 and, 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 
Armrest Stack: 60mm to 70mm in 5mm increments 

Since the Supersonic (J5) was released as a premium bracket with market-leading fit options and versatility, Profile Design wanted to bring similar options to the rest of their range of brackets and aerobars. By simplifying the extension clamp and shifting the wing forward to the bar centreline, they were able to meet their targets. As a consequence of this simplification, the Sonic is the lightest of Profile Design's current brackets. 

The Ergo armrest shares the flippable design of the rest of their 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 a first section at 45deg and the grip at 25deg. They also have a 7.5mm lateral shift per side (15mm total) to allow fine tuning of the grip width. They are 400mm and cables exit from end of extension.

Adorable but Run Very Small!
Size: 11 Little Kid, Color: Pearly Pink
These run very small. I was advised by my sister before ordering that Mini Melissa runs small; however, my daughter is a size 11 or 11.5 and since these run in whole sizes I couldn’t imagine ordering a 12! I would think a size 12 would be a range of shoe sizes 12 to 13. They arrived in time for an event we needed them for but were way too short in length so unfortunately they were returned. They are lovely, adorable, comfortable shoes but run very very small.
