PROFILE DESIGN - SUPERSONIC ERGO 50c CARBON

The Supersonic bracket (previously known as the J5) is the first and premier model of the new generation Profile Design brackets – resulting from careful analysis of the way riders use their aerobars and the adjustments that need to be made. It offers easier adjustment and a greater fit range. Pairing this bracket with the Ergo armrest offers industry-leading fit options and greater comfort. With the 35c extensions, this aerobar is suited to riders who wish to adopt an aerodynamic "arrowhead" hand position. 

The 50c extensions offer a 50deg ski bend shape with a 7.5mm (per side) lateral shift. This allows a neutral wrist angle with the capability to fine tune the grip width. They are 400mm long and can be cut to size to suit nearly every rider. They are drilled for rear-exit cable routing. 

The Ergo armrest is an integral part of the overall adjustability scheme. The dual-offset design (shared with Race and Boom armrests) gives a very precise adjustment range. This, along with the evenly curved shape, allows it to work well for most riders.

The Supersonic/Ergo platform is designed to give riders the freedom to find their best possible position with a huge range of independent adjustments. There are 80 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1440 possible configurations. As a clip-on bar, it is also possible to adjust the extension width and tilt easily.

  • Armrest Offset: -85mm to -17.5mm in 7.5mm steps
  • Armrest Width: 124mm to 290mm in 18.5mm steps
  • Armrest Stack: 58.5mm to 138.5mm in 5mm steps

Great cosplay jacket
Size: Small, Color: Black, Size: Small, Color: Black
I bought a jacket similar to this about 4 years ago and I absolutely hated it. It was cheaply made and so shiny it could blind a nighttime driver. I needed another one because my son out grew the old one. I hated having to buy what I thought would be another cheap jacket but when it came in, I was shocked. Apparently, I bought from a different maker because this jacket was perfect. Well made. Easily ironed out the wrinkles. This turned out to be the perfect jacket for my son. He loved it. I really love it. Very happy with this purchase. Hopefully, I do not have to buy another one but if I do, it will be this brand. I have saved it in my list just in case I do need to order another. It is so nice. Extremely happy with my purchase.

Coat is very nice - - I didn't expect it to be as nice as it is!
Size: X-Large, Color: Black
This coat arrived promptly, and I am very pleased with it. Very wrinkled, but it ironed up real nice. My husband is usually in between a Size L and an XL. I ordered an L first and it was too tight, so I returned it and ordered an XL and it was too big, so I would say the sizing is spot-on. I was able to take up the sides enough that it now looks good on him. The fabric and construction seem sturdy. He is wearing it to an Edgar Allan Poe function, and I think he will look fabulous.

Good fit
Color: Light Grey, Size: Medium
A nice vest and a true slim fit. Good quality for the price and no satin back, the material is used for the whole vest, allowing it to be worn without a jacket and still look smart. I am 6' 3" and 200lbs with a slim build, the Medium size fit like a glove, snug but not tight as a waistcoat should be.

Good Fit, Fold Lines
5'9, around 125-130 pounds, and the Small fit me just fine. Adjuster strap provides a great range of... adjustment. Good waistcoat if you are looking for something quick and cheap. With it being cheap, however, the material suffers. Due to it being folded while in shipping, there are seem lines going down the sides of the waistcoat which make it poke out and look awkward.
