About The Profile Design Sonic/Ergo 39a Aerobar

The Profile Design Sonic/Ergo 39a Aerobars are designed to present minimal frontal area to create as little aerodynamic drag as possible. The main purpose of an aerobar is, of course, to get the rider into a fast position despite a fairly minimalist appearance the Sonic/Ergo offers a comprehensive fit range for exactly this purpose. The Sonic bracket offers an extensive fit range, low weight and easy adjustment along with minimal frontal area. Combining this with the Ergo armrest creates an aerobar that will aid most riders in optimizing their position for both speed and comfort.

  • The 39a extensions have a 39 degree angle for the grip. The rider can choose whether to hold high for the shrugged position or low for a more open, head up position
  • 100 distinct position options achievable just by moving the armrest pads to fine-tune rider fit and maximize comfort
  • 6061-T6 aluminum construction, pre-drilled for bar-end shifter cable routing
  • Compatible with electronic or mechanical shifters

Frequently Asked Questions

Do you offer free shipping?

We do offer free shipping on non-bike orders over $100. We do not offer free shipping for bicycles unless it is a one time promotion. Generally, bike shipping will cost $150 and that covers just the shipping of the bike with no assembly. If you were to bring that bike to your local mechanic or bike store, you would pay them their assembly fee. If you choose our Professional Assembly option for $200, our service technicians would assemble the bike before shipping and then re-pack the bike safely for transit. When you receive the bike you would attach the front wheel, attach the seatpost/saddle, and raise the handlebars and clamp them. Those three items do have to be detached to minimize or eliminate the chance of damage in transit.

How much does shipping cost?

For orders of parts, accessories, apparel, etc. on orders under $100, shipping is a flat rate of $9.99. Regular bike shipping without assembly is $150, bike shipping with Professional Assembly is an additional $200 (so $350 in total which includes the $150 of regular shipping). Our White Glove Delivery option is $699 and that will cover the assembly of the bike and our White Glove Delivery partner delivering your dream bike to your front door, ready to ride!
