Hi, everyone. New here, but have been lurking for a while.
I have wired Cateye Astrale's on my bikes, have been completely reliable. In my opinion they are much less obtrusive than most wireless computers. There are two slim sensors on the left chainstay, and the wire runs up under the down tube. My bikes are dark, but if I had a white one I would just cover the wire with white electrical tape instead of black or blue. I think the only reason I would go wireless would be if I wanted GPS or HRM. Since I don't, I won't.
I had a similar discussion with my wife about cordless mouse and keyboard for the desktop computer. I don't see the point when they never go anywhere, but now we have two more things that need their batteries recharged at inconvenient times!
