I use the Cateye micro wireless bike computer to keep track of my mileage and progress . After my last ride i took it off the bike and noted the odometer mileage at 384 even . I put it in my office drawer and this morning i went for a bike ride and when i went to slip it back on the bike it read 385.6 miles .

Any idea why it would change my mileage when its not even on the bike . BTW i don't open that drawer very much . lol Does this happe to others and if so how do you prevent it ? Thanks .
