I had forgotten that old style cable driven speedometers make some noise.I don't mean a lack of lubrication noise, but a normal moving parts kind of noise. I suppose it never bothered me in my younger days , but it does now.I intend to use the modern speedometer/computers on all the bikes I will ride often for any distance. My favorite 27" ten speed will get one and a set of led lights this week. Any tips on what to buy , or not to buy in computers or lights? I don't want to spend a lot. What about the ones at Wal-mart? Thanks.
