i have some 1 pc cranks, not sure of brand, but the tightening nut has been stripped as well as the thread on the arm. Can i get new nut or do i need a new crank? I hve seen some nice looking 3pc cranks, 4-Jeri tubular, but dont really know if there any god . Plus i would have to buy new sprcket and pedals as well, Tottaling bout £60, not bad but do i need 3pc, and are 4-Jeri good??

profile cranks are the best component you can put on a bmx bike. just get them you won't be sorry.

There should be no question about it. Three piece cranks are the only way to go if you are serious about riding. I would agree about the Profile cranks, I bent the spindle on some Redline cranks, but have had no problems with my Profile cranks.

4-Jeri? I've never even heard of that brand. But three-piece cranks that you can get for 60 pounds (about $115 US) are almost certainly going to be crap.

I'd recommend getting either Profile or Odyssey cranks, or a pair of Solid Hella Lights if you can find a pair. You'll also need to get new pedals, with a 9/16" spindle rather than the 1/2" spindle that cranks for one-piecers use. Your sprocket will probably work fine, but you'll need to get an adapter for it so that it will fit properly on the crankset's spindle.

edit: I just did a Google search for 4-Jeri. Just what I expected. Generic crap.

Thought they'd be crap for silly cheap prices. FSA ring any bells for any1, i really cant afford to spend much, skint 15 year old

I know a guy who uses FSA cranks. He hasn't had any probems that I can think of.

cut some lawns, sit some babies, sell some crack. (just kidding about the crack ) Save up for the good stuff man. I've had my profile cranks for almost 8 years, and i ride everything street, dirt, race. if you treat them good they'll never let you down.

Also check eBay. Profile cranks last forever and a day, so getting a used pair can give you a good value for less $$$. Just look at the pics to make sure they aren't rusted or in really bad shape.

Something like this:

Shipping may be a bit more overseas, but it isn't a 'new' item so you shouldn't have to pay import fees or anything. You likely might find even better prices if you shop around some.

Do NOT get generic 3-piece cranks, they will only be a bigger headache, and most of all, WASTE OF MONEY, compared to your current 1-piece cranks which are driving you nuts.

I've heard FSA makes good cranks, pehaps i'll get some when I need some new cranks.

my friend cracked fsa cranks at the welding. He never even dented his profiles

Which ones they don't make just one crank for BMX.

thanks BMXTRIX, i looked at those but dont understand because i thought there was only euro or standard crank "sizes". Whats the USA bit about and will it fit my Huffy (dont flame it its a light bike)
john

There is not standard or Euro.

There is American (USA), Euro, Spanish, and mid. Your bike is most likely an American (USA) bottom bracket. Don't sweat the confusion - it used to all just be 'bottom bracket' and every bmxer knew what you were talking about.

i'm not sure. all i know is that they were tubular and had a 48 spline spindle

get profiles! if you have more money ao heaver person get the ss ones, but the dj's are fine.

same exact thing happened to my old 1pc. an old gary fisher one. RuBbIsH if i ever saw it. go 3pc. not neccesarily stronger, but i dunno, people seem hooked on em lately, easier to replace the parts.

if you're looking for somthing cost effective.
the redline big block is the way to go, if you can find one.
it's a one peice, but it's thicker and stronger than a stock one peice.
but you will have to get a big block crank plate also because others will not fit.
at about $50.00 U.S it would be well within your price range.
i had one for 5 years with no problems

who would pay 50 bucks for a 1 piece?

warmachine

Indeed. That was a silly question.

3 pc. are stronger. always.

I know that, but i meant how can you be dumb enough to buy it
