The 35c+ is Profile Design's lightweight carbon extension, built from a high-grade carbon layup and sized inside so Shimano Di2 electronics can be hidden in the extension. At 142 g a pair it's a straight swap for any aerobar designed around 22.2 mm extensions.

Highlights

• Straight 35° ski bend for riders who prefer a wrist angle on the low side of neutral
• 142 g a pair, which Profile Design says is half the weight of standard carbon extensions
• 19.4 mm inside diameter takes the Aeroport Di2 adaptor for internal Di2 parts
• 400 mm long, 80 mm rise, sold as a left and right pair

Shape and fit

The 35c+ is a straight 35° ski bend with 80 mm of rise measured bottom to top. Profile Design describes it as suited to riders who prefer a wrist angle on the low side of the neutral range. Extensions are there to put your hands in a comfortable position relative to the armrests so you can settle into your position.

Hidden Di2

Profile Design developed the 35c+ so riders could use its Aeroport Di2 adaptor with a carbon extension. With the Aeroport (sold separately), the extension can hold a Shimano Di2 EW-RS910 junction box and BT-DN110 battery with room for an EW-SD50 cable to pass through. Di2 parts are not included.

Compatibility & fit

Fits any aerobar designed for 22.2 mm extensions. Outside diameter 22.2 mm, inside diameter 19.4 mm. Follow the torque values and cutting guidance for the aerobar you're fitting them to.

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