Profile Design 45/25 SLC Carbon Extensions - 400mm

The Super Light Carbon (SLC) series combines the light weight of the 35C models with the standard carbon extensions. Improvements in manufacturing made it possible to combine the carbon extensions with even lower weight and the current Shimano Electronic solutions. With the 45/25 SLC, Profile Design has designed advanced extensions with a new carbon layup that offer a 50% weight reduction compared to other brands.

The 45/25 SLC offer a 7.5mm side shift. This allows you to get your hands narrower or wider without tilting the extensions so much that the shifters touch.

The SLC was designed to combine two things – the extremely light extensions and a perfect integration of the proven Shimano Di2.

These extensions are designed with the Aeroport, so you can store the Shimano Di2 EW-RS910 Junction Box and BT-DN110 battery with space for EW-SD50 cables. With the SLC, Profile Design sets a new standard for extensions as well as the ability to store Shimano Di2 components cleanly. The extensions are 400mm long and come with a clamp diameter of 22.2mm and a 45/25° handle angle.
