Cateye Cordless 2 question(9 posts)

Cateye Cordless 2 questionkatie1

I have had a Cateye Cordless 2 cyclometer for a few years now. I've had no problems with it until recently. When I am riding, my speed will vary. For instance, according to my riding companions we are going 20 mph, but it will read 8, 20, 15, 25, etc. It's frustrating because my mileage is totally messed up by the end. I tried replacing the batteries in both the computer and fork mount sensor, but the problem continues. The sensor is lined up with the magnet and has previously worked in that position. Any suggestions? Do you think the sensor or computer is bad? Thanks!!!

My Cateye does that when the pick-up is too far from the magnet. The pickup tends to get bumped when I replace the wheel. Try moving the pick-up closer to the magnet and see if the problem goes away.

Tried that. If it was any closer, it would be touching the magnet!

There should be a couple of metal contacts (I think) on the bottom side of the computer and within the mounting bracket itself. Try cleaning those contacts with alcohol. Maybe over time, dirt and dust may have built up preventing a solid contact. Sometimes just repositioning the sensor and computer in relation to one another may help. When mounting my Cordless 7 recently, I moved the sensor from the right fork blade over to the left fork blade because it just worked better. On the left blade, the readings were inconsistent, go figure!

Good luck.

I'll try that. It seems to be worse when it is windy. Any clue why?

I've had the same problem with my cordless when it's very humid or wet. I rode in the fog once and it quit working all together. The metal contacts were the problem. I took off the display and dried the metal tabs and it worked fine.

the reason you're getting the lower numbers is because the sensor is detecting the magnet every nth time around and n < the real number. most often, the speed that shows will be some product of your actual speed and the number of times the sensor has detected a revolution. At 20mph for example you'll most frequently see 5, 10, 15.

my problem was with a new unit, and it turned out that the sensor was defective. replaced it and problem went away. it was so bad, that my mileage was very noticebly reduced. may be that yours has worn out. good news is C2s are available for drastic price reductions ($20-$40 at Performance or eBay).

Well, I must admit it is encouraging news. I thought I had gotten really slow! :) Yesterday, I realized how bad it was when my friend's computer read 75 miles and mine was 52. I haven't really noticed it being that off until recently. I broke down and ordered a whole new kit (computer and sensor) from Performance. It's cheap, and I wasn't sure which part was defective. I hope that solves the problem. Thanks for the input!
