Thanks for the wonderful forum, just stumbled upon it today. I am getting into BMX bikes again, as they're building a skatepark in our town, and am working on an old school project, with slight utilization of some of the newer bmx technology that is available today.
I've recently stripped an old *very light* Diamondback frame, and repainted it. The only thing I'm keeping from the orginal bike is the frame, and the fork, which leaves me with a lot to purchase. I bought a set of cw style handlebars, looking for an old plastic seat, and have some mag wheels on order. I'm sticking with the above, as far as looks go, and have some questions regarding some of the other componants.
First, is there ANY advantage between 1pc, 2pc, and 3pc cranks? Is it simply a mere convienence factor, or will a high quality 1pc crank do the trick? I've never been able to get a solid answer from any of the local riders here, they just suggest the 3pc, but have no idea why it's good.
Is there any advantage over a chainwheel verse a chainring, or is it a matter of preference/looks? If so, what is the advantage of the superior? Are most chainwheels/rings compatible with most cranks?
As far as speed goes, outside of the gear ratio, what component makes the biggest difference, the freewheel, or the crank setup? In otherwords, where should I spend the money if I'm on a budget?
And lastly, are there any compatibility problems I should watch out for, or are most parts interchangeable? I noticed the seat post on the Diamondback was a lot slimmer than the seatpost on my brother's bike which is modern; I'm wondering if I'll run into a lot of these problems, and if so, what are the obvious things to look out for?
Any and all help on any of these areas would be GREATLY appreciated. I want to get this old beast back on the road and in mint condition as soon as possible; got a lot of practicin' to do before the free park is built.
