Bike Computer Install - I Just Don't Get It!
I found a Vetta VL110 for a great price and it arrived over the weekend. I installed it yesterday. There are so many things to track, I really just played around with it on my first trip out (to the store with the kids). Today, I reset everything before I left and couldn't wait to get to work to see all the data I had collected. While on the way, I had it set to AVG/MAX speed. I couldn't believe how fast I was really going! It just didn't seem like I was moving at +76 mph down that hill! Heck, my average was near 50 mph! Needless to say, I have something set or installed wrong. I just can't figure out what. I took the rim size right off my tire, 700x36C, and I've checked the setting at least a dozen times at this point. For magnet proximity issues, I have the sensor mounted very low on the fork, about 3 inches from the hub. The install instructions (very vague) give direction just to make sure the sensor is mounted 2-4 (or more) cm away from the brakes. Now I took "or more" to mean it really doesn't matter, but to me it has to matter. Logically, a magnet mounted toward the tire end of the spoke is going to pass by the sensor many fewer times than if it were mounted an inch from the hub. But everything I read says it doesn't matter where you mount the thing. If anyone here can give me direction or help me reason this out, I would really appreciate it!
