50A Aluminum Extensions

The new range of extensions have evolved from Profile Design’s well proven T-Series. They have been designed to offer distinct fit options. They have also adopted a new naming system whereby the name gives the angle material of the extension. Thus 50a is a 50° bend in aluminum.

Performance

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 50A extensions offer a 50deg ski bend shape.
• The 50A offer a 7.5mm lateral shift per side.  This allows the rider to get their hands narrower or wider without tilting the extensions so much that the shifters touch.
• They are 340 mm long to suit nearly every rider.
• They are drilled for rear-exit cable routing.

Origin

Recent Trends in aerobar fit have been towards higher hand positions, so they’ve increased the rise compared to previous generation extensions.  They have focused on the most popular angles from their previous range and added the 50A. The 50 A was developed to deliver both the lightest possible aluminum 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.

Accessories

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.
