I got a German made Ciclomaster , that is an antique , I got it in the 80's , if I put a new battery in it ,

it works. reset wheel radius number and go.

coin battery goes in a metal screw cap closed compartment. plugs to wired sensor ..

they had one which put the sensor in the side of the computer to count the magnet pulses
from computer being on the fork blade itself.

have the bracket , but used the wire so as to pick my location..
I have it above the Rt Low rider pannier, Below the cantilever brake.



just havent needed a computer, but for an Odometer on Bike tours ..

commuting, get real , all you need is a watch, going to be late? ride faster..
