The Supersonic bracket (previously know as the J5) is the first and premier model of the new generation Profile Design brackets.  It offers easier adjustments and a greater fit range than anything that came before it.

Paring this bracket with the ergo armrest offers industry leading fit options and greater comfort.

The Supersonic/Ergo platform is designed to give riders the freedom to find their best possible position with a huge range of independence adjustments.

Fit Data

Armrest Offset: -85mm to -17.5mm in 7.5mm steps
Armrest Width: 124mm to 290mm in 18.5mm steps (With Extensions at 100mm)
Armrest Stack: 58.5mm (no riser kit) to 138.5mm in 5mm increments (With aftermarket Riser Kit)

There are 80 distinct position options achievable just by moving the armrests.  Combine that with 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.


Extension Shape - The 4525c extensions offer a 45 deg lower and 25 deg upper section with a 7.5mm lateral shift per side.  This allows the rider to choose between a low, short reach position or a high hands, stretched position for aerodynamics.  They are 400mm long and can be cut to suit nearly every rider.  They are drilled for rear-exit cable routing.
