I've got a 48 tooth sprocket on my bike now, but it's not giving me enough torque to get up a rather steep hill on my way to work. I'm pulling around 300lb so I need as much torque as possible. So, will either a 54t or 60t give me what I need, and if so, where can I get one. Any time I see a 60t sprocket online it referes to them as being #35 pitch, and i have no idea what that refers to or if it will work. Here is the link i found. #35 60T Sprocket 4 Bolt I know that I'll have to drill out 9 holes to get it to fit the rim, but will it work in all other respects? If not, any other suggestions out there?
