The 43 ASC extensions from Profile Design are the next evolutionary step in aero handlebars. Only the clamp and the grip area are round. Everything else is kammtail-shaped and therefore more aerodynamic. In addition, the carbon "tubes" disappear completely under the forearm due to the bend, see the competition photo on my Cervélo P5. This works better the steeper you ride the cockpit.
These extensions are the closest you can get to custom models, which are all well into the four-figure range. In addition, the adjustability is still available, which in my opinion is much more important for most pilots, including myself, than looking like a professional.
The key data: 22.2 clamp and therefore suitable for all standard clamps. Inner diameter 19 millimeters, so the RS910 junction box from Shimano's Di2 fits in there. 400 millimeters long, the grip area is 107 millimeters high from the bottom edge to the end of the shifter mount and bent at 43°. 230 grams per pair.
These extensions are also available for shorter people in 340 length here .
The ideal computer holder from 76 Projects is available here in my shop, see also the last picture for mounting at the very front of the round part.
If you are still looking for the right Profile Design arm pads and angle spacers, you will find them here and here and can tune your previously run-of-the-mill looking and feeling cockpit without spending a fortune. And always remember: only those who lie comfortably will lie well for a long time. And fast. Because #aeroiseverything.
Other tuning parts for your aero cockpit are my own grappling hooks and the computer holder from 76projects .
Attention: If you want to assemble these parts and test drive them first and then return them used, please wait until they are available on Amazon. I do not take used parts back.
