My Roubaix gets by with higher gears than my heavy bag laden commuter. I rode it up Mt. Diablo andwas in super low gears carrying a load. My Roubaix, no problems in not-the-lowest gear.
Looks like I will need to sneak out to the mountains as soon as weather allows to see if the gearing is adequate. Sounds like a good excuse anyway!
