at least that's what im told
Well, if the Castro has a 48" bottom gear, then 66" would be correct for the top (137% increase) .. if the Swoop has a 48" bottom gear then it will also have a 66" top (137% increase).. there's a problem with the accuracy of the Tern literature.. using 66 gear inches, different wheel sizes will yield the same top speed given the same cadence, just the smaller wheel will be spinning faster than the larger one ...
