ladies and gentlemen, without further ado, my new mod.
a new grip for the Sigma 1606L
the Sigma’s sensor, held on with zip ties
a closeup of the zip ties and the Sigma sensor
the Philips earphone magnet I glued onto the brake disc, so that the Sigma’s sensor has something to pick up.
Basically, the whole mod took roughly 4 hours of work, from learning how it works, to going out and finding a shop to sell me the parts, some testing to make sure it works.
