PROFILE DESIGN - 52 ASC AEROBAR EXTENSIONS

When designing these extensions we wanted to utilize carbon fibers' natural ability to be shaped into an aerodynamic form while still providing a good amount of strength and rigidity, hence ASC stands for Aero Shaped Carbon.

The 52 ASC follows on from our hugely popular first Aero Shaped Carbon extension (The 43 ASC) with increased grip angle.

The front section (from the wrist fin forward) has been angled up by 9 degrees to give a 52 degree grip angle and comfortable wrist support.

Additionally the grip has been lengthened by 20mm to provide more comfort for users of SRAM Blips. The grip can be trimmed to suit.

The premise of the ASC range is to move the extension sideways to share its frontal aera with riders arm, while maintaining a 22.2mm mounting aera to be compatible with the majority of standard aerobars.

The 52 ASC will be a strong contender for the title of 'most comfortable aero extensions' at least for standard aerobar brackets.

The fit by the wrist area is designed to smooth airflow over the arm and to increase contact area which will provide some extra comfort and to give you more control over your bike. The shape was optimised using CFD to minimise drag without sacrificing strength.

Who is it for?

The 52 ASC is intended to optimize the aerodynamics of your existing bars but pairs exceptionally well with either the Race+ or Ergo+ armrest. Giving you the ideal supportive position which again will help you be relaxed while riding and as we mentioned… the key to speed is relaxation.

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.

So cute and so worth it!
Size: 3 Little Kid, Color: Turquoise
AMAZING for my 7 year old daughter. She can tie shoes but I no longer have to wait on her to do so. It takes 2 seconds for her to put these on and she says that they are super comfortable. We have been to Silver dollar City multiple times and she never complains about her feet hurting! They are easily washed in the washer. They hold up great. I think they are very much worth the money! Fit normal.

Our everyday shoe!
Size: 13 Little Kid, Color: Turquoise
Great shoes and good fit. Fits as expected. The sole has worn down a bit quicker than I had hoped but my kiddo wears them everyday. I would buy them again for sure!
