I got a free bike computer last night. It’s an older used model with a wire, but hey, it was free. It came with the all the wires, a battery, and even zip ties ina Specialized tin can. The can said Specialized Speedzone Comp, and that it had 15 features. But I am not sure that the cyclocomputer that I got int he can was the same one originally came in the can. The only thing missing were instructions.
I put the battery in, and it worked, though it looked like one LCD element is out. Oh well. It is for the least significant digit. It booted up in KM/H mode. I played with pressing the buttons, and managed to get into different modes (avs,mxs,dst,odo,tm). But I couldn’t figure out how to change it from KM/H to MPH. With more playing, I figured out how to set the time. I found one mode where it looked like it was displaying the tire size, but I couldn’t figure out how to change it.
I went to Specialized’s website hoping to find a manual, but didn’t. I searched google, but didn’t find a manual. I found some instructions at Sheldon Brown’s website for a Specialized Speedzone, but they must have been for a different model as they didn’t work. My bike computer doesn’t even have aset button.
I played with it some more, but gave up and went to bed. This morning, I played with it some more, and did some more google searches. I found a review for a Specialized SpeedZone Pro bike computer. It is wireless, but looks similar to the bike computer I got. But it listed instructions of how to program the thing. I decided to try them, and they worked!!!!
The right button is the Mode button, and the left button is Function button. To change it from km/h to mph, I got into ODO mode by pressing the Mode button several times. Once in ODO mode, I had to hold the Function button down, and tap the Mode button. The km/h will flash. Toggle between the km/h and m/h modes button by pressing the Mode button. Press the Function button to save it. It also seems to allow you to edit the odometer reading. Press the mode button to skip to the next digit.
You can edit the tire size from the ODO mode too. Press and hold the Function button till it brings up the tire size screen. Tap the Function and Mode buttons at the same time to scroll through the different tire sizes. It seems that they are all either 26 inches, or 700c. But there is are a bunch of different widths. My wife’s mountain bike has 26×1.95 tires. I had to choose between 26×1.9 and 26×2.00. I went with the 26×1.9. Press the Function button to save the setting.
I got it all installed on her bike, so we will see how well it works. We might go for a ride tonight.
