I have a bike computer, an Axiom Wireless, that I put on my mountain bike. I had it on my comfort bike (26" wheels) and it didn't seem to have a problem but now that it's on my new MB (29" wheels) I wonder whether
the speed and distance, mainly distance, it is showing is accurate. It seems high, I noticed it right away because I ride in the same places I did my other bike and the numbers aren't the same. When I put the computer on the new bike I measured the wheel by rolling it and marking the distance of one revolution. I put the number (90" x 25.4) of 2286 into the computer for tire size but I think some thing is wrong. For instance I road a trail today that is 3.8 miles long, the computer read about 5.3 miles. Now the number on the trail map, 3.8, maybe off but I don't think by 1.5 miles. Any ideas?
