2.How to calculate gear inches for an oval chainrings.

Exactly same way as for round chainring. You just need to use the nominal size in the calculation of an oval ring you have. That is, if you buy 32T oval you use for calculation 32T size. Reason for this is 32T oval chainring has same circumference as the 32T round. We optimize the shape but not circumference - it stays constant. Distance between each teeth always has to remain at 12.7mm to engage the chain properly. You can use any online calculator to get gear inches for an oval chainring.

7.Which size of an oval should I choose?

We always recommend swapping like for like, so if you have a 32T round ring at the moment, you should consider getting a 32T oval. The same applies to our shiftable road ovals, we recommend that you purchase ovals with the same teeth count as your round rings.

8.Will my chain have a greater tendency to drop if I use an oval chainring?

No. If we compare an aB round to oval narrow-wide ring there is absolutely no difference in the chain retention capabilities. But there is a difference among brands (regardless of the chainring shape). This is because every brand has designed the teeth differently and they will behave in a different way when they wear out a little or you use them in the mud.
