RE: [ST] sprockets and speedometers



The speedo is way off anyway. Most of us use a bike computer or GPS to calculate a more accurate speed. In general the speedos on the Sprints are 8-10% on the optimistic side. 

For example, if the Sprint's speedo reads 90 mph, it reads about 82 mph on the bike computer. The speedo reads off of front wheel speed, so a change in sprocket will have no effect on speedo reading.

Cheers.
