    Help! Changing cog size to shift wheel rearwards!

    OK, here's the deal. On my Inbred, I'm running a wussy 32x20 gear ratio, and with a massive Kenda Nevegal 2.5 tire in the rear, the side knobs of the tire are terribly close to the edges of the chainstay. I have 2-3mm clearance at most. The chain is about tight as I'm willing to make it right now. Adding one more full link to the chain will make it too long, even with the wheel shifted all the way to the rear.

    Please help me prove/disprove my hypothesis here, folks. If I go to a 19T cog in the rear, I'll be able to keep the same chainlength, but be able to shift the wheel rearward but a bit, thereby giving my tire a bit more clearance?

    Any thoughts? Thanks in advance!

    Yes. Fewer teeth + same chain = more length. Approximately 1/4" more.

    Cheers, Aeroplane.

    No half-link, sorry - I've been told repeatedly about how the rigors of singlespeeding don't favor the use of half-links.

    i dont know about that half link theory. i use a hlf link on my recently (used to be SS) fixed MTB and my fixed roadbike no problems on either one for over a year and a couple thousand miles between em. but the lowering 1 tooth advice is good.
