Im not gonna get into it.. But its pretty obvious who is in it for quality.
Look at Phase Two and Rad, both companies have been working their asses off for a few years to make some quality dirt scoots.
I respect when someone spends time on a project and goes an extra step to make sure it makes riders happy, even if it means they will be behind other competitors at launch day.
Madd and a few other companies seem to be trying to take advantage of the interest and some leaked designs to make a quick buck in my personal opinion, but thats just how business goes.
To answer a few questions...
Plastic cores are shit for more than a few reasons lol.
You really ought to use a set of aluminum split hubs Dom.
Ive shattered plastic hubs and got a blowout because it punctured my innertube.
The tire psi threading count is a big part in its speed too, a higher psi will give you more speed.
So you will need new 80psi Tires if you want to get the most speed.
Your best bet for getting hubs is to grab a set off an old E200 scoot, which can be hard to find sometimes.
Forks..
There will be a few aftermarket forks yes, but BMX style forks are perfect for the dirt scoot. 4130 Chromoly tubular forks will more than likely be the most common fork because its super durable and easy to make.
Myself and Danny Rambert still have not bent a single dirt scoot fork.
