    i've decided.

    at least one bike will have bmx cranks, in order to run crazy-ass bmx chainrings like this:

    http://www.phantomcycles.com.au/prod...cat=161&page=1

    or, you know, along those lines.
    have:ea50 flats, black, light, stiff.
    144 bcd 3/32" 49t sugino track chainring, possibly 75.

    want: risers, light, stiff, 1", black if that can be
    144 bcd 46t or 47t chainring any kind or width

    you have to start that young?! crap!!!

    but yeah, there are some fixed gear bikes at the bike polo games here with a ratio of maybe 1.5:1, and you can get some mad skids with those.

    as far as bmx cranks...i know most chainwheels are pretty small, but i know i can get them up to 44t, which is about what i like...i have 43x17 now and love it. i just have to figure out bb compatibility, chainline, etc.

    I'm in. I've been looking for an artistic cycling frameset and a cycleball set, I don't have the cash right now but I did find this: http://www.langenberg-manufaktur.de/index2.htm check out the indoor and radball sections.

    do you need a special sort of frameset for that? there was a guy at the west side invite doing some stuff like that on a trashed-up conversion.

    radball...well...lives up to its name. i keep trying to get people to play it with me. i know i'll suck, but we all will at first anyway, right?

    I'm sure with a little skill you can make anything work, but radball frames have the seatpost coming out of the back of the top tube, you're sitting super over the wheel. I'm guessing that has something to do with weight distribution when "kicking" the ball with a wheelie. also the handlebars are wierd, but that should be an easy fix.


    there's a couple radball vids on youtube

    oh, right. i was talking about bike dancing. i'd noticed the radball frames before. i also notice they use a smaller ball...seems like it's for ease of hopping the front wheel over the ball to shoot/stop it.

    carleton--that's pretty much what i have in mind. i may do a different chainring...but that one is sort of cool. i mean...most bmx chainrings that are cool are as dorky as they are cool, but it's that mixture that makes me want one.

    oh, but what bb are you using, and how'd you get the chainline straight?

    you can get euro bearings for bmx cranks.
    then the chainline is adjusted over spacers.
    ...but the axles are usually w i d e.

    hmmm, yeah. the gold would also work on my miyata--the lugs have gold striping around them.

    god, i never thought i'd have a bike with a speck of gold on it. though, as i've said before, a tiny touch of gold can be tasteful.

    Profile makes a "euro" BB for BMX now. Before about 6 years ago BMX bikes had to PRESS their BBs in. Now they screw in like road/mtb. When that transition happened, they made BBs to mate with the BMX crank arms and chainwheels.

    Maybe try this for your setup (make sure to choose the "European" BB option: http://www.profileracing.com/loader....&productid=118

    I'm sure that you can contact Profile and get the width of the BB spindle. They are a cool group of folks.

    That bike isn't mine. It belongs to "Big Dog" a messer in Baltimore. But, this pic shows that your idea will definitely work.

    oh, okay, i thought it was yours.

    i've just read a few posts on here with people trying to calculate chainline with bmx cranks (fugazi dave was one, maybe i should pm him). i suck at math pretty badly, so i'll probably just copy someone else's setup.

    Keep in mind that that price includes the bottom bracket. Profile is tops in the game used by top pros etc. There are other options:

    Bizhouse, $80 (arms only):


    Check Danscomp.com and flatlandfuel.com for more BMX-style options.

    On flatlandfuel.com:
    Arestic Ice Metal Crank Euro 165mm (with bottom bracket)
    List Price: $149.99
    Sale Price: $104.99



    http://obmx.com/itemdetails.cfm?id=3217&catalogId=150
    PROFILE - MINI MAGNUTANIUM 3-PIECE CRANKS (138) $300.00 (with bottom bracket)


    Keep a lookout for "Flatland" specific parts. BMX Flatlanders are weight weinies and run short crank arms starting at around 160mm (even down to 140mm).

    Just wanted to clarify something here..

    There are 4 different BMX bottom bracket standards now, and a host of axle sizes/splines.

    American - big 68mm unthreaded shell, requires press-in cups with bearings
    Euro - When BMX started getting weight concious, they started releasing these.. unfortunately the bearings don't like side loading, so while MTB guys may be into 'external' euro bearings, its pretty much gone in BMX.
    Spanish - smaller BB shell than American, unthreaded, machined for precise fit. Bearings must be pressed directly into the frame
    Mid - Very similar to spanish, only with a different bearing size.

    The standard axle sizes are 19 and 22mm. Most sprockets have a 22mm hole in the centre.

    Here's an older George French article on the matter:
    http://gsport.kishmish.com/tech/bbs_again.php
    ^note that 'mid' doesn't exist here, and he's proposing a press in standard similar to American, but with Poly cups, called the 'Yorkshire'.

    Further clarification: American BB's were originallly used with one-piece or "Ashtabula" cranks. A lot of old bikes have these cranks, so they will take an American crankset/bb quite well. However, a lot of Huffys and Schwinns had proprietary BB sizing, so it might be a little harder for them.
