The 43 & 52 ASC (Aero Shaped Carbon) extensions take advantage of the design scope offered by carbon fibre to offer a highly optimised shape.
The grip section is placed at an 87mm rise, 43º angle, then the body of the extension is swept up and outwards to hug the riders arm as closely as possible.
 The shape was optimised using CFD to minimise drag without sacrificing strength.
Origin
The 43 & 52 ASC is intended to optimise the aerodynamics of your existing bars and pairs well with our Plus Series armrest kits.
Who is it for?
The extensions will fit in any aerobar that is designed for 22.2mm.  So can be used by any rider wishing to improve the comfort of their aerobar grips.
Accessories
These extensions were designed with the Aeroport in mind, so they can fit a Shimano Di2 EW-RS910 junction box and BT-DN110 battery with room for an EW-SD50 cable to pass through.
