Speedometer question

[GW's Motorized]

I just bought a speedometer for a 27 inch wheel, I run a 27.5 on the front of my bike. How much will half an inch effect the speed read on the speedometer?

Is it a bicycle computer? The entry number for a 27" is 2155 for a 27.5 the number is 2194.

No, it's mechanical Cable driven, it was a second hand buy, so it has no cabel or mount, but everything else is there and it has 0 miles on the odometer.

I was just going to fab up a mount. I was also going to go to the parts store sometime and see if they have a speedometer cable that will work

Difference should be negligible, don't worry about it.
