35 SLC Carbon Extensions


The Super Light Carbon (SLC) series brings the low weight of the 35C + to our standard carbon extensions. 

Improvements in manufacturing allow us to upgrade our carbon extensions for lower weight and the ability to fit Di2 parts inside using the Aeroport.


The sole purpose of extensions is to provide a comfortable position for the riders hands relative to the armrests. They enhance performance by allowing the rider to relax into their optimal position.  Which is why we provide different fit options so each rider can chase their best performance.

Fit Data

  • Extension Shape: The 35 slc extensions offer a 35 deg ski bend shape. This facilitates a slightly turned down wrist position to create a streamlined hand position.
  • The SLC extensions offer the same range of ergonomic options as the previous generation but the weight is halved. This also allows Di2 parts to be fitted inside the extension.
  • All the extensions have a 22.2mm diameter in the clamping area.
  • They are 400mm long and can be cut to size to suit nearly every rider.
  • They are drilled for rear-exit cable routing.


The 35 SLC was developed to deliver both the lightest possible
carbon extension and to offer riders of high end bikes the ability to use
our Aeroport Di2 adaptor with a carbon extension. Extensive testing
was required to achieve this target.

    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.


    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.
