BMX - First BMX bike advice

Hey, do you have to put on cup and bearing in at a time then the spindle then the other cup and bearing? Because if that is right, how do you use a cup-press if the spindle is sticking out one end?


I put the cups in first. then the bearings. bearings should go in easier then the cups.

We're talking about a headset cup press, not cranks.


I'm talking about people buying them for personal use

Is $4 too much to spend to make one?

**** that

If you paid $3k for a custom frame, I don't think you'd just "Bang in" the cups.

Nope. And it's not a road bike. I was making a point about the fact that it seems like a good idea to spend the $4 rather than damage your frame or headset. To these kids, $100 may be a lot of money for a tool, but if you've spent a couple hundred on your frame, why not spend $4 or so to make sure your headset goes in flush? Don't make me post a pic of the biek on here, the BMX kids hate that.

If you do it right and take it slow, a rubber mallot and some 2x4's will work just fine. That's what I did, and nothing bad happened and the cups are perfectly flush. But if you have the time, or you're not certain about hammering away at your cups then a cheap home-made press isn't a bad idea. On the other hand though, if your frame and cups can't take a little pounding from a rubber mallot without working fine after (as long as you're careful) then I'd suggest not riding your bike with those cups and that frame. But that's just me.

A press starts the cups in properly. The wood block/mallet works, but at some point one of your cups may not be totally square as it goes in, which is bad for your head tube. I don't have any frames cheap enough to risk a bit of damage.
