Hi All

I purchased this gear set from an ABB member many years ago and intend to install it soon, however all my reference books not to hand, and not sure they will help anyway...

Apparently, an AutoDelta close ratio set; attachment shows two main shafts and 8 separate gears, and shifters etc... Part number shown where known and number of teeth on all gears also shown.

My question is how to I calculate the overall gear ratios for the five gears and then how to match with the best rear axle ratio - here I am thinking, 43/10. Usage road and road rallies only, very little track.

I am thinking perhaps Competition Reference Manual would resolve but nothing to hand....

Many thanks
