Gear Ratio in toploaders
I will be rebuilding my toploader in the next few weeks - Naturally David is the source for the parts! - Looking at his site , I noticed a 2.90 first gear is now available - got me thinking, exactly how are the Ratios determined for first gear in the toploaders - Wide Ratio - Input 23 teeth - Cluster 30 teeth - First gear 32 teeth - I'll be the first to admit I was challanged in math class, so I would appreciate an explanation on the method of determining how you arrive at 2.78 - Thanks very much - Ed
