    3 piece crank vs 1 piece crank... which is better? Why?

    Ok, I finally made my mind up on a bike. I am new to this so I want a good entry-level bike. I settled with the Haro F3 however a friend of mine told me that a 3 piece crank is better than a 1 piece crank. He never told me why, so can someone answer this question for me.

    I really don't want to spend more than $300 on a bike. The Haro F3 is $230, but if a bike with 3 piece crank is really a whole lot better than a bike with 1 piece crank. Then I'll get the F5 for $370.

    Also, are there any other bikes under $300 that I should consider looking at before buying the F3?

    -Thanks

    Well a three-piece crank is a lot stronger than one piece. I have found that a one piece has a tendency to spin on you while doing tricks. A three piece will not. A three piece has sealed bearings (or it should) which means smoother peddling and less mechanical trouble. Get the three piece its worth the extra money. You will end up replacing your 1 piece anyway.

    Three piece cranks are stronger than 1 piece because of material usage amount of it, the spindles that accompany them are made stronger, as are the bearings and races. It is mainly about the material used. Some 1 piece use hi-ten steel some use cro-mo. Some companies like Profile and Odyssey use 4130 cro-mo that is cold forged or heat treated for strength. Profile and Odyssey both make a crank that carries a limited lifetime warranty on it. You will never ever se that on a 1 piece crank.
    If you are going to be doing any jumping or street tricks then it would be alot easier for you to use a 3 piece as you will be replacing 1 piece cranks way to often not to mention possible injury due to a 1 piece crank breaking or bending on a landing and creating a ugly injury.

    keep in mind that if you purchase a low end/low cost three piece crankset you may as well throw your cash in the garbage.

    ride the one piece cranks until you can afford decent 3 piece.

    profiles are like $135.00 and hold up great.

    there are plenty of junk 3 piece. you get what you pay for.

    Yeah, as all the other people said, GET THE 3 PC CRANKS!! They are alot stronger and more reliable. You will have smoother rides and your 3 pc cranks wont spin while doing tricks. This will add a whole new look to...riding your bike!!

    Hope This Helps

    I understand the whole concept "You get what you pay for" but considering I'm a beginner, I don't see the sense investing $150 in a crank just yet. With that in mind, what would you recommend, a cheap 1 pc crank, or a cheap 3 pc crank?

    Never go "cheap" you can go inexpensive but never "cheap." Having said that 3 piece is always better than one. Redline makes a couple of inexpensive 3 piece cranks as does FSA. I carry both and are satisfied with both.

    Just do it, you'll be happier in the long run, I use to go thorugh 1 pieces bearings like once a month abck a few years ago, and it will be one of the best $150 you've spent.

    1pc

    i see all the bikes have them now, but I have a one piece sugino cro-mo crank for
    ramp, ground, racing, freestyle, i never had an issue with it,
    i 'd say ride it (the one pc) til you break it, unless you like spending money.

    -the crank is on my 1984 haro sport, and before that was on my patterson bmx. those cranks are one of the few things that never was replaced. i still own the bike and ride it.

    I'm not a big fan of Stolens but a good bike for under 300 is the Stolen Pinch at 300 even or the Stolen Riot for a little under 300.... or the DKs like the Siklon, Havok, Reaction, or Cygnus 20in..... but it all depends on what size top tube you want... or look at the Subrosa Salvador Dirt or the Subrosa Tiro... or Black Eye NFG, Drifter, De La Cruz... or The 2-Hip Forcedown..... Look at Danscomp.com for bikes too.
