I am curious about raising the gearing, (lower numerically). The stock H2 uses 44/18 gearing and uses a 118 link chain, the H2R is 42/18 and uses 116 links. I guess my question is there enough adjustment to allow a smaller rear sprocket with the 118 chain? If not, I guess you might be able to go to a 19 front if there is enough room. The stock gearing is 44/18 (2.44), H2R is 42/18 (2.33) and with 19 on the front it is 44/19 (2.31).
