Description
The Sonic bracket offers an extensive fit range, low weight and easy adjustment along with minimal frontal area. Combining this with the Ergo armrest creates an aerobar that will aid most riders in optimising their position for both speed and comfort.
The 52a, 39a and 26a are the newest versions of our reliable aluminium extension range
The A-Series extensions now allow the rider and fitter to fine tune the wrist angle without changing other aspects of the fit. The dimensions are optimised for use with our plus series armrests.
