Extensions 52 ASC | Profile Design

Presentation

When designing these extensions, we wanted to exploit the natural properties of carbon fiber, allowing us to create an aerodynamic shape while ensuring rigidity and strength. This is how the ASC range was born: Aero Shaped Carbon.

The 52 ASC follows our very popular 43 ASC model, with a more pronounced grip angle.

The front part (at the wrist) is raised by 9°, offering a grip angle of 52° as well as excellent wrist support.

The grip has also been lengthened by 20mm for improved comfort with SRAM Blips shifters. It can be shortened as needed.

The philosophy of the ASC range is to offset the extension laterally so that it shares its aerodynamics with the forearm, while maintaining a clamping area of ​​22.2 mm compatible with the majority of extenders on the market.

The 52 ASCs are serious contenders for the title of "most comfortable extensions" on standard attachment extenders.

The design around the wrist was conceived to smooth airflow over the forearm, increase the contact surface, improve comfort, and offer greater control on the bike. The shape was optimized using CFD simulation to reduce drag without compromising strength.

Who is this product for?

The 52 ASC extensions are designed to optimize the aerodynamics of your existing extensions. They pair particularly well with Race+ or Ergo+ armrests for an ideal, comfortable, and relaxed riding position. And as they say: the key to speed is relaxation.

The extensions are compatible with all extensions using a clamping diameter of 22.2 mm – so they will suit any cyclist looking to improve their comfort in an aero position.
