Profile Design - Sonic Ergo 35aPROFILE DESIGN SONIC ERGO 35A REPLACES THE T4+ 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 its fairly minimalist appearance, the Sonic Ergo offers a comprehensive fit range for exactly this purpose.

PROFILE DESIGN - SONIC ERGO 35A

REPLACES THE T4+

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 its 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 

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. According to Profile Design, this is the most adjustable clip-on bar on the market (and in history). 

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, Profile Design was able to meet these targets. As a consequence of this 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 35a extensions offer a 35deg ski bend shape. They are 400mm long to allow a wide range of riders to fit. The cable routing is designed to exit from the rear of the extension.

Tough Chewer Approved but Not a Forever Toy
Flavor Name: Original, Size: X-Large
I do like this toy for what it is meant to do. It is definitely built for strong chewers and holds up way better than softer toys that get destroyed in minutes. The texture keeps dogs interested and gives them something to really work on, which helps with boredom and can support dental cleaning through chewing. It is one of those “finally something that lasts a bit” kind of toys for heavy chewers. That said, it is not something you just toss in and forget about forever. Like most hard nylon toys, it will wear down over time and should be checked regularly for rough edges or changes in shape. Some dogs will also go through it faster depending on how intense their chewing style is, so replacement will eventually be needed. Girl, this is one of those “it survives the chaos better than most, but you still need to keep an eye on it” situations.

Clean teeth as well!!
Flavor Name: Bacon & Chicken, Size: Small
If your dog is a chewer or just bored, these bones are amazing. All of my dogs love and have loved Nylabones. I consider them a must to give your dog as an outlet to chew when bored or when in need of stimulation. Replace as necessary. I always have a pack on standby.

Great fit
Flavor Name: Peanut Butter, Size: X-Large
My dog has a very powerful jaw. Only a few things that he cannot destroy. We have had the peanut butter flavor that still looks the same that it did a year and a half ago. It is his version of a binky. He may leave it alone for days or weeks but every so often he needs to have his teeth and gums itched. Very few remnants of the bone left around.
