    hey its newbie again....

    if i'm trying to squeeze a few extra miles outta my back tire, is moving the tire a couple inches along the rim a bad idea (to gain a few more skid patches)? Are there any other methods to do this?
  1.  
    thats alot of work just get a gear ratio that gives you alot of patches like 48x17 that gives you like 17 or something
  2.  
    48x19 (what i've been running) is 19, just find what works for you and the terrain you're riding and go from there. Generally every time you run a 17t, cog you'll have 17 skid patches.

    that would be the most basic way to gain more life without changing your ratio,
    try this calculator i thought it was pretty cool

    i messed around with it for a bit and it seems accurate

    cool thanks...

    a buddy of mine seems to think that if you remove the chain, turn the wheel a couple of teeth, and then chain-up again, you'll achieve the same results. i just don't see this working since the cog is fixed to the wheel.

    this would work if, and only if, you kept the cranks/chainring from moving while you turned the wheel. the idea is to shift the cog relative to the chainring; once you reattach the chain they will move in tandem again.

    as others have already pointed out, a "relatively prime" chainring/cog combination is the best investment if you plan on doing a lot of skidding. for example, 17 tooth cog with any chainring besides a 51 tooth.

    I read somewhere just to change the cog position. As in just move the cog from the chain like 2-3 teeth and it'll be on a different spot. I haven't tried this though so I wouldn't know if this is right.
