Magic 4130 CrMo made from powder of the unicorn horn?
Design? What? 7 CrMo Tubes that costs almost nothing?
The only things to acquit price that high is:
1) Extra-extra-extrea-super-ultra-superiour cosmic NASA level designing and quality control.
2) Extra-super-duper-mega testing with paying salary to riders for testing.
Testing, RnD, taxes, you think other companies that produce frames don't pay for all that? Good BMX frames are cheap and superior strong. CHEAP and STRONG.
The main features of mass street-trials frames are:
1) Reliability
2) Geo
Even "chineese-shit" because frames that costs 170 pounds are pretty strong and reliable. And you can't beat physics. So Arcade may be just top frame like other top street/dirt frame in terms of reliability. Arcade can't be better, because of physics(metal fatigue) lol.
Geo is something you need to develope/try/change/try - yes, it can be pretty costly, but this process takes place in developing of any produced frame in the world.
About small quantity - pfff bull****. Especially for company that have so much experience, established ties with factory and their own RnD.
