Got a 24" Inspired Fourplay and want to try gearing it up a bit higher. Right now it has a Trialtech 16t freewheel in back and a Surly 22t front cog. What I'd like to do it put on a smaller freewheel but I can't find any freewheels that fit the rear hub that are smaller than the 16t. If they don't exist then maybe I guess I'd like to experiment with a larger front cog but I can't seem to find anything larger than the 22t... WTF... Anybody got any ideas ?
