Step 1: Change your front wheel size to 19" on the bike computer.
Step 2: Done! ;D
Are you mounting up a 19?
Nope, just changed the setting to fix the speedo error, thought you might be interested.
Hank - I was just perusing some old threads and thought I'd let you know that this trick has been confirmed to work with my GPS (didn't have the GPS when I first did it). The speedo is within +/- .5 mph of the GPS. ;D
I'll have to do that. Thanks for the tip!
