    Anyone running smaller gears for clearance?

    A lot of bmx riders are running smaller gears so they can grind stuff and have more clearance. It makes sense on the trail too.

    It makes sense if you need it, but I've never needed that much more clearance. The big downside is how much faster your ring, cog and chain will wear out

    Not into it personally. Shorter radii of smaller rings and cogs increases drivetrain friction. Fewer teeth carrying the same load means they wear out faster. I run as large a ring as I'm comfortable with, in the case of my 29er that's a 36t ring plus a 24t cog.

    But then I don't grind. Log-overs and occasional rock crawling is as bad as it gets for me.

    Plus I imagine my rides are quite a few miles longer than the average BMXers'.

    Smaller chainrings? Nope, I'm running bigger wheels.
    Authorities speculate that speed may have been a factor. They are also holding gravity and inertia for questioning.

    More teeth are better. Use a bashring if necessary.

    I run a Syncros 24tooth chainring up front on Sweetwing cranks and a 12tooth Chris King cog out back not for clearence issues but because it looks Awesome and it's SICK LIGHT!
    I got some pretty decent Niners!

    Make sure you run a quality chain. The microdrivetrains in BMX lead to a lot of snapped chains.
