Thanks and the shock gets mounted into the hole just below the first weld of the seat tower and then the bottom is bolted to a linkage that you can't see in the picture. The shock ratio is 2.57 and it will be using a 10.5" x 3.5" shock with a tail that has a heim joint bearing, thus giving you the opportunity to lower the bottom bracket and slack out the head angle or vice versa. I'm not the builder of the frame my buddy is! I took the picture but will put more up as it comes closer and closer to becoming the riding Frankenstein! Arquitetodh Thanks for the props!
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.
Nope this is Brian's then Daniel's will be made to his liking. More or less this is the testing mule to see what or if anything needs to be changed, which I'm sure will happen but that's what testing is for. But does that bike not look like it eats boulders for dessert!
Production will be down the road the bike has a few things left to be made for it, then of to heat treating and then testing to see what improvements need to be made to it. Production will be all hand built and for those who want a hand made bike still! If you want more information on the bike contact Adrian Cortina at adrian@cr1engineering.com to get him fired up to finish these bike's!
John I will get the specs up once we figure it all out. It's in prototype stage right now so things may change after one ride but I will get the current specs up asap!
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.
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.
