    BMX Cranks on a SS

    Hi...

    I'm getting ready to build my first SS and found some 180 Red-Line cranks on eBay. I'm wondering if they would work well? I'm building it out of a '99 Fat Chance Yo! Eddy. It currently has an XTR bottom bracket (I think; don't have it in possession just yet; has XTR cranks). It seems like this is a relatively inexpensive set of cranks, but not sure it would work well. Does anyone have any experience with using the BMX cranks on a SS mountain bike frame?

    Thanks in advance.

    Jim.

    you'll probably need a new bb and you will have to figure out what length spindle you'll need for it. if you are using a freehub with spacers adjusting the chainline will be easy. It shouldn't be that tough if you can find the right bb.

    The nice thing about BMX cranks is that they usually a floating spindle. You can use spacers to adjust where everything sits and the chainline. Lots of dirtjumpers are riding 3-piece cranks and SS. Just make sure the spindle is long enough.

    You will have to get rid of the XTR BB, not compatible.
    You will need a crank setup that has the 'Euro' (vs. american, mid or spanish) BB.
    the Euro style will thread into a std MTB BB.

    you will also need a chainring, or a sproket (same thing just diff't names according to who you buy from).

    if you want HUGE selection, go with a 1/8 setup.
    otherwise Profile makes an 'imperial' CR that is 3/32 and runs from like 24-46t or so.

    you can dial in the chainline with spacers, so if you have a fixed chainline on your rear hub, it is a nice option.

    they also have major 'cool factor' as they have some pretty interesting design/color options available.

    I like the rigidity of the cranks, but they are not without their own inherent problems.

    they are HEAVY, a PITA to install IMO, you have to get an locking/adjustable Euro BB if you don't want to constantly retighten your BB cups.

    my opinion is that the only ones worth having are at least as expensive as comparable tradtitonal MTB cranks.

    BTW, you want 3-piece style only.

    better be ready to chat with people on the trail if you get a set.
    that may or may not be an issue for you.

    Thank you, Thank you, Thank you.

    I'm either going to run some kind of cool BMX cranks, or Middleburns. I have ridden a bike with the middleburns; they are awesome. Stiff is good. Heavy, well the rest of the bike is going to be killer light.

    Quick question for you mrsalty: Are you running BMX cranks on any of your SSs? It sounds like you are. I don't mind being a bit different.

    The additional parts you are talking about wouldn't be a big deal to add and still be under the price of a set of Middleburns.


    Here are a couple of links to the setup I'm looking at:

    I personally use a pair of FMF cranks on my SS. They're light, cheap and I've had no problem at all. fmfbmx.com

    profile are outstanding. they'll last 20 years. I have some ones from the 80's in my garage we just took off a bike to put on some stylos. But wow. They dont come much stiffer than the profiles. Ti bolts and spindles are readily available and many many many lengths and some sweet sprockets are also there to chose from.
    I'd recommend them if you're looking for some burly cranks that will be maintence* free and will last forever.

    *Maintenence free if you dont include the retightening of the crank bolts every month or so.

    Yes,
    BMX cranks on my SS setup

    I think the first link (black set) has a Euro BB, but I would ask to be sure.
    the second set looks like American or maybe mid style. Those will NOT work on a MTB (the BB will not work that is; the cranks will mount on a 19mm spindle, and that spindle will go on any of the Mid, Amer, or Euro style BB)

    I think you could get some of these, if you wanted the cheapest/best value for a new set
    FSA 'nasty boy'

    this is the set that Shiggy recommended to me (really heavy, even for cro-mo cranks)

    http://www.findbmxparts.com/nasty-cr...uro-p-221.html

    just make sure you get the BB that has the lockring on it (FSA makes one for like $25 if you have to buy it separate).

    If you have the jack, the Middleburns are supposed to be fantastic.

    Mr Salty is on top of this, all good info. You can get the FSA X-Drive BB from Niagra Cycle Works for something like $33. It will be for a 19mm spindle which seems to be the most common, it will not come with a spindle. I just put a set of Profiles on my Jabberwocky with the FSA X-drive BB. Setup is fine if you follow the directions from FSA to the T. the 5 3/4 inch spindle that came with the Profile arms was just the right length but you should take a look at your frame and measure how wide a spindle you are going to need.

    triumph - great rig! I'm in the market for some handlebars for my 26" cruiser - yours don't look to have the huge 8" rise found on pro bars, but they're taller than cruisers -- so what are they??

    I use Profile cranks on my bikes:



    The weight issue is way overblown compared to others.

    Thanks, my bars have a 5.5" rise. I think they are cruiser bars. They do look bigger in the photo though.
