What they said. (Forget wireless.)
The wireless systems always seem to be temperamental, the sensors are
HUGE and of course there's another battery to worry about. Another plus
to a wired system is that you will get more computer for your money than
what you would get by paying for the wireless feature.
I have two bikes with computers wired for both speed and cadence. The
wires, as well as both speed sensors, are "glued" to the frame using
silicone. The wires and sensors were held in place and the frame masked
with blue painter's tape prior to placing on the silicone bead. After
the silicone set, the masking tape was removed to provide a clean edge.
(Some smoothing of the edge is required before the silicone completely
dries.) I find this to be superior to the use of clear tape that some
people recommend and a VAST improvement over the nylon cable ties that
come with the computers.
The older bike has an (impossible to find now) TTT stem that has a hole
specifically designed to route the computer wires down the headtube. The
newer bike doesn't even have enough clearance between the tire and the
top of the fork to snake the wire past - even if modern stem designs
allowed for that. So for the new bike, the speed sensor wire is routed
down the front brake cable housing and both are contained in nylon weave
tubing
(

that matches the cable housing color (in my case - black.) The cadence
wire was also enclosed with the nylon weave together with the front
derailleur cable housing until it got to the downtube. At that point the
wire exits the weave and is routed along the bottom of the downtube.
The installation took two of us several hours to complete - but the
results are well work the effort. The installation is even more
unobtrusive than a wireless system because the sensors are MUCH smaller.
And the old wire harness has been on the bike for about 20 years. I've
replaced the computer a few times, but since all wired computers use the
same simple reed switch for a sensor, I've always been able to connect
the old harness to the new computer (with a minor issue of cutting and
soldering the wires.)
If anyone is interested, I can take some photos of the details and post
them on the Web.
Cheers,
