Hi everyone
I have a wisper 905 standard. It is working fine but the speedometer seems to be out.
I have been comparing the the distance and speed on the bike to the 2 apps on my android phone.
There is a difference every time. Now I know the gps in the phones can be inaccurate, but the difference is the same every time.
The bike is %80.3-80.5 of what the apps measure.
That's been done with 2 different phones and many different routes.
How does the wisper measure the speed? The cankset had been changed and it is a 52teeth
I just really would like to know which one is the right number.
Hope this makes sense.
Thanks
Greg
