mounted old computer on new bike and making a strange new noise
I have a cateye velocity 5 computer that I had mounted on my old bike since 2007. I only put about 600 miles on that bike. Anyways, I noticed it was making an odd sort of electronic clicking/beaping noise. It is not the magnet hitting the sensor, I've triple checked to make sure. It is however making the noise when the magnet passes the sensor. I don't recall it making that noise before but maybe I had just gotten used to it or something but I don't think so. I did just reset it to put the odometer back to zero.
Anybody know why it could be making this noise? I might have thought it was normal if I hadn't used he same computer before.
Cateye (and others) computers use a reed switch in the pickup unit attached to the fork. The reed switch produces a faint clicking noise as the electrical contacts close when the magnet comes into close proximity of the reed switch.
My Cateye Strada makes a distinct clicking sound with every wheel revolution.
Yeah, and I think the change from steel to carbon fork is amplifying the sound. Hopefully I wont be able to year it while riding. I can probably try to put some kind of rubber padding between sensor and fork to muffle the sound.
