Avocet was started in the 1970s by Bernie Hoffacker and his sons Bud and Neal. The Hoffackers were owners of the highly-regarded Northern California bicycle shop Palo Alto Bicycles. In the late 1970s they developed a prototype small cycle computer. Being in Silicon Valley they were able to find expertise to refine it into what would become the most popular cycle computer ever, the Avocet 30. Greg LeMond used one, as did whole European teams such as Panasonic. Even Ironman triathlon winner Dave Scott used an Avocet computer.
For a while, they were everywhere. Avocet says that in the 1989 and 1990 Tours de France, 80% of the riders using a cyclometer were using one made by Avocet.
Avocet expanded its offering to include tires, saddles and other accessories. The company at some point changed hands and though there is an Avocet web site, the firm appears to be dormant.

Here's an old Avocet Cyclometer ad.
Note: All of the cyclometers for sale on this page, unless otherwise noted, come with their harnesses.
