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

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.
