Accessory handlebar adapter for aerobars

This is designed to attach a second, dummy handlebar to aerobars. Aerobars usually take up all the space on the main handlebars, leaving no room for lights, a Garmin mount, etc.

It bridges the gap between the skis like so: https://i.ytimg.com/vi/fzLn_ayGTPk/maxresdefault.jpg but is more secure.

I made this for use with a Profile Design T3 set of aerobars, to mate to a standard 31.8 mm dummy handlebar. I use the dummy handlebar that came with the Profile Design set. I haven't installed it yet, but I don't see why it wouldn't work. If it doesn't, I'll update this.

STL & SLDPRT are provided for your convenience. Printed successfully with Lulzbot Mini with 3.0 mm PLA, using Cura.

Assembly & Materials

• 0.2" wide zipties.

If have a hard time understanding the purpose of this, see here:

Tracks for zipties are provided for ease of installation. You might have luck with adding inner tube shims to increase friction. With weightier objects like lights, they may rotate & eventually end up at the bottom once you run over enough bumps. I designed this around some fairly standard zipties, with about 0.20" width.

Updates =======

26 Jan 17: added a picture with what I had to do before. It kept rotating forward with a light mounted every time I hit a bump. Don't recommend.
