DIY Manual Shifter Kit
Sometimes having a single drive sprocket is a bit limiting. A shifter kit is a very attractive add-on because it can give you the powers of multiple sprocket sizes. But those kits are expensive! If you're willing to settle for a more manual setup, you can make your own multiple-sprocket setup. Max350 from motorbicycling.com installed a 36 tooth sprocket over a 44 tooth sprocket, and made a segment of chain that's removable with two master links to fit the chain on to a the larger sprocket. Simple, and does the trick if you're willing to carry plyers with you on a ride! Although I would bet that you could make this setup even simpler by using a spring-loaded tensioner! You wouldn't even need to fiddle with master links!
