35c Extensions

The 35c extensions offer a 35deg 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 every rider. They are drilled for rear-exit cable routing.


The Supersonic bracket (previously known as the J5) is the fi rst and premier model of the new generation Profile Design brackets. It offers easier adjustment and a greater fi t range than anything that came before it. Pairing this bracket with the ergo armrest offers industry leading fi t options and greater comfort. With the 35c extensions this aerobar is suited to riders who wish to adopt an aerodynamic ‘arrowhead’ hand position.


The Supersonic was the first of our new 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 armrests) 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.


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