I've had particularly bad luck with the wires of wired computers.
I switched to wireless, and have generally done fine by them.
My regular road bike has a Specialized -- the yellow-button model.
Worked great, but got mussed up by a really nasty rainstorm. I
took it in to the store and they said, "Oh yeah, that's been a
problem with some of these", and promptly replaced it. The
replacement's been fine in the rain ever since (though I haven't
taken it out in as nasty a rainstorm).
Last month I bought a cheap Trek Incite 8i (on sale at East Prov)
for my travel bike. I'm not sure it enjoyed being in the luggage
hold, because the last digit wasn't visible initially -- but after a
day or two in Germany, it was fine. More importantly, I actually
prefer its interface. The digits are much nicer, and the settings
work out better. If I were to buy a new one, I think I'd actually go
with the Incite (once I've had a chance to test it on a few more
flights and made sure it recovers every time).
I can't imagine not using a wireless, especially given their relative
cheapness these days.
They are very easy to install. The magnet goes on a spoke. The
sensor goes on the fork, and straps on with quick-ties. The
computer goes on the handlebar (some will also mount on the
stem). So far, this is just like installing a wired bike computer.
Now for the magical part: you're done! There is no wire! (-:
It takes a minute or two to configure the computer for your wheel
-- these days most come with presets for the standard sizes.
It takes a minute or so to line up the magnet and sensor just so,
so you do get a signal but the sensor doesn't strike the spokes.
(The sensor needs to be closer to the magnet than you might
expect, and it takes a minute to perform this leap of faith.) But
that's about all there is to it. I would estimate that the total
installation is under ten minutes, and feels like less than that.
Even a person without mechanical skill (eg, me) can do it.
So: if you've used a wired bike computer, this is even easier. If you
haven't used either, I recommend getting a wireless one. I'm sure
many of us would be happy to help you negotiate the installation
process (I certainly would be willing to).
