    skid / spin zones?

    What's the deal with these? What does having '16' skid / skip zones (according the one online calculator of it) for a 49-16 ratio mean when compared to having '1' skid / skip zone for a 48 -16 ratio?

    it basically means you'll have to spin your tire less. skidding in one spot every time (or 2 if you can skip/skid with either foot forward) will eat the crap out of that one part of your tire while leaving the rest intact.

    It means the number of places on your back tire that could be in contact with the ground when you skid. There is math involved that can get complicated, but basically you want the ratio between the cog and chainring on a fixie to not be a whole number. With 48/16 the rear wheel goes around exactly 3 times for every revolution of the cranks. You skid on the same spot every time. 49/16 gives 3.0625 revolutions, so every time you end up with a different part of the tire on the ground.

    has anybody ever worn through or seen a dramatic amount of wear on a tire in a single spot from skidding skipping?

    I need a new rear tire every month or two due to tire wear

    I would occasionally blow out a tire due to excessive wear in a single spot, until I switched to armadillos

    hmm...2 tires a month. Seems to justify putting a hand brake on. lets say you spend 20 bucks on each tire thats 40 bucks a month.

    $480 a year on tires alone!

    brake pads = $5-15 year and tires last several months.

    Yeah, but then you lose the magical ability to know what everything around you is going to do.

    one tire a month, rear only, so $240 a year... it's a small price to pay,

    I still want to know where this online calculator is, anybody know?

    I think that that chart ranks as one of the best things ever posted on this forum.

    If I understand this right...

    If I was running a 48-16, and switched to a 47-16, there would be 15 more skiddable spots on the tire, which would in theory prolong the life of the tire?

    Yes. Because the wear is distributed randomly over 16 spots on the tire, thus prolonging your tire life.

    The yellow zone is for loading and unloading only. There is no parking in the red zone.
