thats looking great, my only concern is that it has a really narrow down tube for a down hill bike, it may be thicker but theres a lot less surface area welded to the head tube.

 Believe me it's made by a freak of nature when it comes to building DH bikes and suspension tuning. Adrian Cortina knows what he's doing, he's been building DH frames at the age when most start puberty and the bike will be beat down hard to find any weaknesses before the bike is ever has a for sale tag on it and it will be made in low numbers not a mass produced machine so quality will be top notch.

 At CR1 a lot of the things Adrian designs are inspired by Motocross. If you look at an old Cortina DH-8 the linkage which they designed 10+ years ago it is very much motocross inspired and this new DH is just that but with a lot of new technology put into it. The carbon fiber inserts will be both to keep mud, rocks, etc. from getting into the linkage area but it also add strength and makes the bottom section more rigid, although testing and bashing will needed to be done on this bike to find what needs to be tweaked and what doesn't. Weight of the bike as a prototype will hover around the 40+ lb. mark, once it's dialed and ready to be a production model weight will be shaved in areas that will not take away from the integrity of the bike and it's handling.

 Fluider, yes he has been experimenting on exactly where he wants it. To answer the question the is yes 99% is that's where it going to be

 Looks like it uses a very large eye2eye (the ratio isn't 2:1 is it?), there's a small triangle in within the bb area and a hole in the top tube that the shock connects to.
