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. 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. Performance - 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. Origin The supersonic was the first of our generation brackets - resulting from careful analysis of the way riders use their aerobars and the adjustments that need to be made. The Ergo armrest is an integral part of the overall adjustability scheme. The dual-offset design (shared with Race and Boom armrest) gives the most precise adjustment range of any armrest on the market. This, along with the evenly curved shape, allows it to work well for the majority of riders. Extensions - Extension Shape: The 35c extensions offer a 35 deg ski bend shape. This facilitates a slightly turned-down wrist position to create a streamlined hand position. They are 400mm long and can be cut to size to suit nearly ever rider. They are drilled for rear-exit cable routing. - Bracket: Supersonic - Clamp Diameter: 31.8mm (26.0 w/Shims) - Armrest: Ergo / 10mm Pads - Armrest Width: 124mm to 290mm in 18.5mm steps (with Extensions at 100mm) - Armrest Offset: -85mm to -17.5mm in 7.5mm steps - Armrest Stack: The minimum is 58.5mm and the bracket is compatible with our existing risers which add up to 138.5mm stack with (70mm of spacers added)
