## Description

This is the most adjustable clip on bar on the market (and in history) The main purpose of an aerobar is to get the rider into a fast position and despite a fairly minimalist appearance the Sonic/Ergo range offers a comprehensive fit range for exactly this purpose The extension length and rotation can be easily adjusted using the top bolt There are 100 distinct position options achievable just by moving the armrests Combine that with the risers and this bar offers 1500 possible configurations As a clip on bar it is also possible to adjust the extension width and tilt easily It is worth noting that our previous top level clip on aerobar, the J4/F35 (featuring on carbon clip ons), offered 90 possible configurations This increase highlights the significant step forward we have made with our new generation aerobars in allowing riders to precisely adjust their position The Ergo armrest shares the flippable design of the rest of our new generation armrests that means by swapping sides or rotating the armrests, smaller increments of movement are achieved â“ making it simple to fine tune a rider position or match the position from their previous aerobar or bike Extensions are 400mm long to allow a wide range of riders to fit The cable routing is designed to exit from the rear of the extension Armrest Offset: -70mm to -2.5mm in 7.5mm steps Armrest Width: 124mm to 290mm in 18.5mm steps Armrest Stack: 60mm to 70mm in 5mm increments Weight is 559 grams
