Profile Design 43 SLC Carbon Extensions bring low-weight carbon construction to a 43-degree ski-bend aerobar profile. Sold as a right-and-left pair, they weigh 140 g per pair and feature a matte black finish.
The 43 SLC shape places the hands in relation to the aerobar armrests, allowing riders to settle into their preferred riding position. Each side offers 7.5 mm of lateral shift, making it possible to set the hands narrower or wider without tilting the extensions excessively.
At 400 mm long, these Profile Design aerobar extensions can be cut to size for a tailored fit. Their 22.2 mm outer diameter suits this standard extension format, while updated manufacturing also supports routing Di2 parts internally using an Aeroport.
For riders refining the fit of a Profile Design aerobar setup, the 43 SLC Carbon Extensions combine a defined ski-bend hand position with trim-to-length adjustability and lateral fit adjustment.
