Thanks everyone for the input. The thing I really like about my present gearing is that it really is an all-around, good gearing for various circumstances. For example, on the flats, I almost never have to use the highest gear, and when I do (slight downhill or wind at my back or perfectly flat conditions with no wind), I don’t feel like I get to a high enough speed to where I’m just spinning (40kph and higher easily with no spinning feel). And the 30-34 is decent for the mountains.
But, on the other hand, I can definitely imagine how on Wuling, after 2500m of climbing with much more to go, I’ll be regretting the decision not to go for a 32 and I’ll be cursing all those in this thread that told me I didn’t need to make the switch. F*&^%$ bast&*$$ on forumosa, I can imagine myself saying.
Edit: But I wonder…if I were to change to a 32, would this necessarily change things for the highest two or three gears with the large cog at the front? Does changing to a 32 change everything around?
