We’re starting a new feature on Monday mornings: in place of the Pic Of The Day we will be showing you a Monday Mystery Pic. An anonymous source has shared with us photos from his collection of cycling history. We will be posting them every Monday morning at 7 am EST for you to offer your best guesses in hopes of winning the admiration of your fellow cycling technorati. So, let’s get started…what do you think this is?

The answer will be posted in the comments section on Tuesday!

If you would like to send in your own Mystery Pic to be considered for the Monday feature, click here and attach your photo with all pertinent information.

This seems to be an hub magnet for an Avocet Cyclometers

It’s a wheel magnet from an Avocet computer. Clips on the spokes around the front hub flange. Used to love my lime green Avocet.

I think Matt is right – it’s the magnet from an Avocet computer, if I recall correctly.

It’s an Avocet cyclometer magnet. Attaches to the spokes using zip-ties. I remember the Avocet 25, 35 and 40 series using this as it supposedly provided a more accurate reading.

This is an Avocet three-prong transmitter for 36-spoke wheels. The 32-spoke version had four prongs.

timbo is correct, this will fit perfectly on a 36 spoke wheel, but will not fit on a standard 32 spoke wheel.

Yup… the others have beaten me to the line. Avocet hub magnet for a 36 spoke wheel. Actually you could make it work with a 32 spoke hub/wheel.
The hub side prongs on the magnet ring had enough grip and you moved the sensor on the fork out just a bit to accommodate. I ran these on my Campy 32 hole hubs for years.

No way that is a magnet!

It is the Acme Super-X3 composite jockey wheel.
Easy recogniced with it’s three low-profiled and heat dispersing teeth.

A magnet? … come on people! 🙂

It appears to be part of a prototype monocle frame without the glass.

Definitely an Avocet computer hub mount magnet. As already stated, it would work for a 32 hole hub if you didn’t mind a slight wobble after forcing it on, but this one was intended for 36 holes.

I guess I’m not the only old fart here. 😉 Yup, Avocet magnetic pickup. I had mine on a Univega Superstrada — never should have sold that one — a Cannondale touring and then a De Rosa. Old times…

Aww, I didn’t think that many people would get it… Timbo, you’re a repository of cycling knowledge!
Touring lockring removers tend to baffle people when they look in my tool kit.

How ironic, I removed an ancient Avocet rig from my wife’s hybrid yesterday and threw the computer mount, the cable, the sensor, and this ring magnet into the trash. But I still have a working Avocet setup on my 18 year old Serotta.

Answer: Most of you were spot on! It’s an Avocet computer magnet.

From our source:
“Avocet was the first commercially available bicycle computer.
It only took 15 -18 months to deliver after it was first announced.
…it was announced in 1982 and delivered in 1983-4.
There were a lot of tech problems and the unit was vastly oversold.
It was difficult to set up and very finicky.
The original was a Model 25.”

Thanks for playing and see you next Monday morning!

It’s a sensor ring for an Avocet 20/30 bike computer from the 80s/90s. I have one still. THAT WORKS.

It may well be an Avocet computer magnet as others are saying, but when I first glanced at it I was reminded of the lockring used on Shimano Nexus internally-geared hubs. I now realize that part looks a bit different.
