91 gear inches would be a killer on the open road unless the conditions were perfect.
No hills here, but I'm finding that the headwinds are killing me. Funny. I had 75 g.i. on it before -- I threw the 52t chainring on for fun--and it is awesome with a tailwind, but not so much fun with a headwind or even a freeway overpass.
