From what I've learned in 30 seconds of shoddy researching, bike computers have been around since the 1980s. And up until a couple of years ago, pretty much all of them had wires between the speed sensor and the computer itself.
Man, what a pain.
Nine times out of 10, the wire develops a kink, which turns into a short, which turns into a new computer entirely. When people come into the shop looking for a computer, I always steer them toward the wireless ones.
For one, they'll probably want us to install it. The wireless ones take way less time. Also, they're just better. The one I use -- the
Cateye Strada Wireless -- is the best. Or, rather, it's the best I've messed around with. I'm sure there are other good ones out there. I just like this one a lot, for a few reasons.
1. It's easy to use. There are no buttons on the top or sides. To cycle through the data, you push the whole computer down. It clicks on each press. Speed is always displayed and the click cycles the rest of it.
2. It can be mounted on the stem or handlebar. And you can change positions if you need to.
3. It's small and lightweight. But it's also easy to read.
It should be noted that the wired Strada works exactly like the wireless model. The mounting bracket design is also the same, and for some reason doesn't account for wired version of the computer base. So, basically, when you tighten down the wired base, you're pinching the cable. Pretty stupid. I went through two wired Stradas in six months before getting the wireless one.
Pony up the bucks and get the wireless version. Actually, that's good adivice no matter which computer you're buying. Mostly because I don't want to be the one stuck zip-tying a bunch of wires to your bike.
