Profile 5 1/4″ Gun Drilled Spindle Aug 6, 2009

All you fixed gear riders who wanted to run Profile cranks, but didn’t like the wider q-factor, Profile has answered your calls. I’ve been riding their 5 1/4″ Gun-Drilled Spindle for a few weeks now and it’s so much better than the standard bb spindle. You can set them up with just a cone against the cup and no spacers now. Doing so leaves about a 3/8″ between the crank arm and my chainstay, drastically shortening the q-factor.

Grab one here at Profile Fixed under the options for spindle length.

    how is that 42 tooth chainring?

  • prolly

    The ring is fine, the Krull is a total waste of money. I did 1 chainring grind on it and the fucking thing warped like a pancake.

    I’m riding a 42t Tree Lite now.

    how do you grind on a tree lite?

  • prolly

    I’m sure you could get a bmx chain and grind on it. Momentarily, I’m not doing any grinds.

    i dont know see why having a wider “q-factor” is bad, i’m on standard profiles with a 33t tree and the wider base makes pedal grinds 100 times easier.

  • prolly

    because you’re riding fixed and you’re always pedaling. BMXs q-factors are even wider than mtb or road qfactors.

    What is the Q factor on this set up? In my brain i came up with 133mm. does that sound right? Good Looks

    Where did you get the 42 tooth tree lite?
    what are your thoughts on it now that you’ve had it for a bit?
    is it 3/32” or 1/8”?
    just curious…
