help me build my bmx from the frame up

I have a 24" race frame, want to build it for mainly playing, some park riding, possible a little racing. What would you put on one if you were starting with a bare frame?

One thing I would really like to do is put a rear disc brake on it. No brake in the front. What hub would you reccomend and how to mount it? I know they make adapters for frames without the caliper mount, just not sure if it would be worth the hassle.

I'm open to any suggestions, there are no lame suggestions in my opinion.

TIA

if you want to put pegs on it and ride in the park doing grinds and such I would NOT put a disk brake on it.

you are no doubt going to bend the rotor and those things are expensive. I would just run whatever brakes the frame has mounts for.

as for the rest of the parts, there are so many companys making quality parts, just get what ever you want. if you ride hard, you will be replacing them anyways.

14mm rear axle is pretty much a must.

Thanks pnj- I just got finished with an order from danscomp. What a pain! Are all BMX suppliers this hard to order from?

Can anyone suggest another source for parts?

I went with v-brakes since I already had a good one in the parts pile. My frame has 3/8" dropouts in the rear, so I ordered a wheelset with 3/8" axles against your's and my kid's advice. I bought a cheaper rear hub thinking if I bend the axle I can later mill out the dropouts and get a high end rear 14mm hub. Which brings up another question...

Freewheel or cassette hub? I went with freewheel, mainly because we have a few spares laying around. What's best though?

haha Dan's is known as the corporate *****s of bmx mail order.

try Albes.com or https://www.staff-bmx.com or trendbmx.com

as for what is better. cassette or freewheel.

we could argue for days on this one....


I like a cassette because it allows me to run a smaller gear in the rear. this allows me to run a smaller sprocket making my bike harder to high center on ramps and stuff. (not sure if that is the correct terminology but imagine your car w/ small tires and then imagine it w/ large tires. your car can go over larger obsticles w/ larger tires. i can't change tire sizes but I can change front sprocket sizes and it has a simallar effect.)

smaller front sprockets are harder to bend too as there is less torque on them when you land on them. (and you will, if your going to try grinds) but if your on a 24inch frame, your going to be running a smaller gear and larger tires anyways. so it's not really going to matter much to you, I don't think.

smaller rear sprockets allow you to have smaller dropouts on the rear and it's harder to grind your chain/sprocket if it's hidden under your dropouts.

but I've ridden freewheels for along time and they work just fine too. so it's really a personal preferance.

the bottom line is, get your bike together and go have fun.

if you ride hard, parts will break. there are better parts for somethings than others. light parts are good for racing but will break easily at the park....

what was the trouble with Dans? just curious.

Turned out that dan's did okay. I spent about 3 hours yesterday with my son, his 20" BMX bike, my Bullit, and a borrowed 24" mtn bike trying to figure out the gear ratio I wanted, plus all the other parts. It's not all that simple when you are comparing a "feel" to a bike with different size wheels. Then I made out this huge order to dan's spec'ing the Shimano cassette hubs that were on sale. I was going to build my own wheels. To make a long story less long, they emailed me last night saying that I had filled out my info wrong (the website's fault) and that the Shimano hubs were sold out. That ruined my whole day, since I had built everything around those hubs. I called them this morning and they were cool, ended up doing things a little different. I actually ended up getting my wheels built by them for less than it was gonna cost me to buy the psrta and build myself...
