Somebody might want to double check my math here but going from a 26" tire to a 28" tire is roughly an 8% increase. So if you up the tire by 8% you drop the gear by 8% so that would effectively turn 4.30's into the ballpark of 3.90's. Closer to like a 3.98 so I guess we could say that 4.30's with a 28" tire would put you between a 3.90 and a 4.10.

Some reason that just seems a bit off so please someone double check my math and let me know if I screwed it up somewhere.
