Singlespeed & Fixed Gear - gear inches
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
May be a silly question---If I mix and match cogs and chainrings,if the gear inch value is the same,will that mean that the chain length will work for all combos?(I have converted a multispeed)
no. the combined cog/chainring tooth count will need to be constant (or at least close to it) if you want to use the same chain.

Let say you have running a 48/18 ratio, it has a gear inches of 70.3 with 23c tires, but 43/16 gives you about 70.6.
That's a huge different in chain length, you have to shorten/lengthen your chain to make it work.

48/15, 16,17,18,19 and 46/19 - using the same chain length. Depends on where your axle is at in the dropouts.
