Profile Design Hypersonic 50a low profile and aggressive

The Profile Design Hypersonic 50a is for riders that want a lower profile and more aggressive position getting the armrest as flat as possible on top of the base bar.

The Hypersonic bracket offers our new generation fit range in a low stack, undermount format.  Pairing this bracket with the ergo armrest offers industry leading fit options and greater comfort.  With the 50a extensions this aerobar encourages a neutral wrist angle.  The Hypersonic/Ergo platform is designed to give riders a low stack bar with easy adjustability of extension length and rotation.  The Hypersonic style bar has been part of our range for over 20 years and remains popular among riders who want an easily adjustable bar with low stack. The Hypersonic is our most ergonomic design in this style to date.  The Ergo armrest is an integral part of the overall adjustability scheme.  The Hypersonic/Ergo/50a aerobar offers comprehensive yet simple adjustment, ideally suited to riders wishing to add aerobars to their road, gravel or packing bike.


  • Extension Shape:  A 50a extensions offer a 50° 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.
