well, if i had say a 34t rear sprocket, could i still cruise around town at say 20mph without any ill effects? how fast litterally would the acceleration be. Say theoreticly if i was to be driving in traffic, with the 34t on, at a stop light, would i beable to stay in the main traffic lain when the light turns green and not slow every one down. meaning would i accelerate so slow that it would be cumbersome to other drivers? thanks

Sounds like you need a jackshaft setup. The ability to change gears opens up a lot of possibilities.

Jackshaft idea sounds like a good idea and is most likely what he "needs". I'll throw a stupid idea out there. Mount two sprockets on back wheel with a spacer in between them. Links would have to be added or removed as you changed sprockets. In a perfect world the idler pulley "thingy" would help enough to make adding/removing links unnecessary.
In answer to bbike1 generally speaking, I myself would think that any sprocket you decide on would not turn you into a "combersome" driver. Just the revs/noise would change.

I have hit 40 mph on a 44T, I'm sure a 36T would get your jollies.

I won't say you'd have "brisk" acceleration though.

alright, i here what your saying. I would LOVE to beable to change gears, but iv just had these wheels built and not willing to tear it appart again, nor spend 350.00 buck to have that setup as of now. That being said, later on this summer, I will be building a bike that i would really love. I am planning on this being my main ways of transportation. From what iv have seen, alot of bikes on here are cheaper bikes (mostly being steel frames and are in the sub 400 price range). These bikes are typically heavy so I am alsothinking that my very light aluminum frame should help in the speed department. My bike in total weighs 26 pounds with my light wheels on and 28 with my heavy duty wheels on, so sounds like the 36t would make me quite happy, considering you can hit 40mph on a 44t, the 36t should have me going 45 id think
