    Cateye v3 and MapMyRide.com don't match?

    Hi-

    Got a new v3 a week or so ago.

    My Saturday ride was 55 miles according to the Cateye yet 68 miles when I mapped the same exact route on mapmyride.com when i got home.

    yes, i have the right tire circumference set.

    happened to notice yesterday, that my magnet was more than 3mm away, and on yesterdays' ride, my speed and cadence would drop out or just stay real low/slow for a while.

    after putting the pick up back to within 3 mm, seems like today's ride was accurate.

    anyone seen anything similar?

    hate to think mapmyride is that inaccurate...or the v3 for that matter.

    thanks!

    If the magnet was too far away from the sensor then it would not have counted every turn of the wheel and there for would had recored a shorter distance.

    In New England we have nine months of winter and three months of damned poor sledding.
