I've riden in the mountains and I ride with a 38 tooth rear sprocket. Riden with around 300 or more pounds on the bike when on a road trip and had no issues. Perhaps going up a huge incline I would have to ride in 4th but thats no big deal. I'd never go back to stock and would not go lower than a 38 tooth. The highway riding is also way better at higher speeds as the rpm's aren't as high.
