Spedo 10% under ???

Post by NEDan » Sat Sep 06, 2014 8:08 am

I've had plenty of bikes where the spedometer was 10% optimistic but never 10% pessemistic.
While out with my GPS on the spedo shows an exact 10% less than actual ie spedo shows 60mph GPS indicates 66 mph.
On the plus side my 40k mi bike just might only have 36k, (sorta) :?
Anyone else experience this?
Any guesses as to the cause?

Out of all my bikes,I've had only one that's been accurate.
Most show faster,my 88 shows 70 and gps shows 64.
I've looked into it too...nothing...no means for user calibration.
Not worth sending it off either.
