PROFILE DESIGN - SONIC ERGO 50A 

REPLACES THE T1+ 

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 the simplification, the Sonic is the lightest of their 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 50a extensions offer a 50deg ski bend shape. 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 the end of the extension.

Comfy, great quality
Size: 6-10, Color: White
I’ve had these for quite a while now. They are holding up very well as i wear them a lot for work (coaching). They are very cushiony and most importantly, they do not slip! I would compare these to Bombas but at a significantly better price point.

My favorite socks now!
Size: Medium, Color: Deep Sea/Breaker Blue/Electro Pink
I love socks! And these are quickly becoming my favorites! They do not slide down into your shoe no matter if you are working out or just wearing them for normal everyday use. The price is a little higher than I would normally pay for 3 pair of socks, but after wearing these for a few weeks, I think the quality and comfortability of these socks is well worth the money.

Quality, comfort and support.
Size: Medium, Color: Deep Sea/Breaker Blue/Electro Pink
These socks are the bomb! If you are athletic or on your feet for extended periods these great looking, well made socks are constructed to offer just the right amount of compression and support. The toe is soft and thick. I will order these again and again. Hopefully Amazon will add even more color choices on the future.
