Sonic Ergo 43a Aerobar

The Sonic/Ergo platform offers a large range of adjustment in everydimension – enabling riders to optimise the comfort of their position. This bar can be used for draft legal triathlon once shortened to meetthe ITU rules. Our new Sonic bracket has been designed as the successor to the J2, which has been a somewhat ignored part of our range. With this update it brings our new generation fit range to a wider range of pricepoints, replacing the J2 bracket. The Ergo armrest has been created to offer both a huge upgrade in fit range as well as increased rider comfort with a supportive curve to cup the arms.Performance The Sonic/Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible. The main purpose of an aerobar is, of course, to get the rider into a fast position despite a fairly minimalist appearance the Sonic/Ergo offers a comprehensive fit range for exactly this purpose.Fit Data Armrest Offset:-70mm to -17.5mm in 7.5mm steps Armrest Width:124mm to 290mm in 18.5mm steps (With Extensions at 100mm) Armrest Stack:60mm (no riser kit) to 130mm in 5mm increments (With aftermarket Riser Kit) 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. This is the most adjustable clip on bar on the market (and in history). It is worth noting that our previous top level clip on aerobar, the J4/F35, offered 90 possible configurations. This highlights the significant step forward we’ve made with our new generation aerobars in allowing riders to precisely adjust their position.Orgin Profile Design had great success with the T3 extension from ourprevious range of bars. The 43a is an enhanced version of that popular extension with more precise shaping to follow the riders arm.After we released the Supersonic (J5) as a premium bracket with market leading fit options and versatility we wanted to bring the same kind of options to the rest of our range of brackets and thus aerobars. By simplifying the extension clamp and shifting the wing forward to the bar centreline we were able to meet our targets. As a consequence of the simplification the Sonic is the lightest of our current brackets. The Ergo armrest shares the flippable design of the rest of our new generation armrests. By swapping sides or rotating the armrests smaller increments of movement are achieved – making it simple to fine tune a riders position or match the position from their previous aerobar or bike.Extensions The 43a extension offers a ‘wrist relief’ style bend that is intendedto allow the extension to hug to the arm for improved aerodynamics without sacrificing wrist comfort.Along with the neutral angle the grips have a 7.5mm lateral shift to allow the rider to fine tune their hand position
