not quite that simple, your'e forgetting that his front sprocket might have a different number of teeth to yours, I assume you have an 11 tooth sprocket on the front cohiba?

10 front and 72 rear was being run by someone last time I was there, similar to what we run with leopards

craigbraber- you are aiming for the revs not to exceed 15,100 at the end of the longest straight, if you know what revs you are getting then you will be able to adjust the gearing to suit from the tables in the manual (can be downloaded if you don't have one)
Or as a rule of thumb each tooth you change by on the rear sprocket will alter the revs by 200rpm

A change of 1 tooth on the front sprocket has a far larger effect on the revs, a change of 1 tooth on the front is rougly equivalent to ten teeth change on the rear

ie a 10 front sprocket and a 90 rear gives a ratio of 9:1

likewise an 11 tooth front sprocket and 99 rear gives a ratio of 9:1
