Default Re: lousy gas mileage

Simplify, my man, simplify.

A 52 tooth is about 18% larger than a 44 tooth. The engine of a bike with a 44 tooth sprocket at 25 mph is turning the same speed as a 52 tooth bike at about 21 mph.

In other words, no, if you are riding at 15-20 mph, the sprocket is making no difference in mileage.
29/10ths cubic inches of raw power.
