The Super Light Carbon (SLC) series brings the low weight of Profile Design's 35c+ to its standard carbon extensions. Manufacturing improvements cut the weight and let you fit Di2 parts inside with the Aeroport.

Highlights

• 45° lower section, 25° grip: hold high for a shrugged position or low for a more open, head-up one
• 7.5 mm lateral shift per side to fine-tune grip width without the shifters touching
• 400 mm, cut to size to suit nearly every rider
• Drilled for rear-exit cable routing
• Takes a Di2 EW-RS910 junction and BT-DN110 battery with the Aeroport adapter

Fit

The 45/25 has a first section at 45° and the grip at 25°, so you can hold high for a shrugged position or low for a more open, head-up position. The 7.5 mm lateral shift per side lets you bring your hands narrower or wider without tilting the extensions so far that the shifters touch. Profile Design increased the rise compared with its previous generation of extensions.

Di2 inside

Designed with the Aeroport in mind, the 45/25 SLC can house a Shimano Di2 EW-RS910 junction box and BT-DN110 battery with room for an EW-SD50 cable to pass through. The Aeroport Di2 RS910 adapter is sold separately.

Compatibility & fit

Fits any aerobar designed for 22.2 mm extensions. Follow Profile Design's SLC extensions installation instructions.

Aerobar fitting and position set-up is a separate workshop service and isn't included in the price. Our workshop can fit the extensions, cut them to length and set up your position.
