Nice work.

Thanks Benk, that will be a helpful chart for a "quick look" at what different gears will do. However, in the U.S., the value for PI is 3.14159....

.....so you may want to check your calculated values. (Maybe a wee bit of sarcasm in there!!)

Re: Nice work.

Don't stress the pi thing. The difference between the commonly accepted 3.1415926... & the other commonly accepted value of 22/7 that benk used is only about 0.04%.

You'd be lucky if you did not lose a full couple percent of top speed to wheelslip. The value of pi does not detract from the usefulness of the spreadsheet.
