I'd assume you were trolling...but I like this. I haaaaaate non split races.

Got an old loose bearing headset I'll try it on first. braces for people thinking i'm serious..
Actually serious. I've only done it on my DJ bike (current one and others in the past) because that's the setting where I want to be able to swap forks from suspension to rigid semi-regularly without it being a PITA to swap the race every time, but it's always held up fine.

What is a split crown race except a crown race with a split cut in it?

For those who use Bike-Components.de, do they charge AU GST as required like CRC/others? Or should I be budgeting for a 10% sting in the tail?

Steel frames and a tighter fit.
Isn't steel more inclined to flex than aluminium? As for fit, I had assumed they were of same tolerance - tight!

Also not doing the load, distance, or in dusty/wet/muddy conditions.
I'd imagine that bmx BB often take a lot more force, but I couldn't imagine a lot of people pushing out the same sort of distance on a bmx!

or more though.

I thought they did. Bought tyres, it was added into the cart when I specified Australia, I think....been 8 months

Bit of force, and a lot of spinning, I would have thought. Unlike an MTB where you upshift and then its a heavy load again....at least in my mind. More about the distances and conditions though.

I'm thinking forces from big landings without suspension. But there probably aren't many riders smashing that out for 50km.

If you've watched much BMX racing.....I don't think you'll see many landings with big forces...its all pumped or smooth. MORE about the distances and conditions, like I say. Most BMX is in short bursts, not lots of them (compared to MTB riding) and in more favourable conditions (asphalt or groomed, drained gravel)

Hurts. Requires Money. And is nerdy.
Yeah bmx is heaps easier on parts :rolleyes:


BMX bb’s have larger bearings.
Steels much stronger than aluminium, and isn’t as soft so tighter fits are possible.

Dirt jumping and street isn’t easy on bearings, the shock loading and the G’s you pull on the transitions are larger than your giving credit. Sit and spin doesn’t equal quicker wear. It actually gives better wear because the load is spread more evenly.
