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

So cute and so worth it!
Size: 3 Little Kid, Color: Turquoise
AMAZING for my 7 year old daughter. She can tie shoes but I no longer have to wait on her to do so. It takes 2 seconds for her to put these on and she says that they are super comfortable. We have been to Silver dollar City multiple times and she never complains about her feet hurting! They are easily washed in the washer. They hold up great. I think they are very much worth the money! Fit normal.
