That's how you get ejected over the bars and rip your headtube off.

I think that is a really elegant looking bike. Not sure about the fabrication type, and I am sure it is coming of age, but it is pretty amazing to look at!

76 degree seat tube is a pretty common thing nowadays. It goes with a lengthened front center and slack head tube. Helps with climbing.

Yup, definitely within the norm, from most major manufacturers too

Funny how they commented on the headtube as well. I've seen it happen. I was on a ride with a guy who's headtube ripped off when he landed. He jumped up and ran to the woods to check his junk. Funniest ***** I'd ever seen. He ended up breaking his orbital socket.

Wow, that is something!

Check yer junk!

I once had an ATAC fork fail on my Yeti at the landing of a series of jumps. Slammed straight to the ground head first. I thought the bars had come loose. had the etto helmet and everything. All that did was dig a deeper hole in the ground with my head.

Those were the days.

It was funny as hell he jumped up and did that. His toptube and downtube dug into the ground pretty hard and flipped over onto him. His was an aluminum frame with shock on the front. Did the jump, came down. Headtube and fork went one way, frame the other.

I've been pretty lucky I haven't had anything major happen. One Scott thermoplastic mountain bar and 1 chain. And the bar came off in my hand while racing. Didn't get hurt, didn't even stop pedaling.

Did he smack his head against a tree?

We're being distracted by angles. Focus on the technology, which opening up so many design possibilities to solve problems with existing frames, including cable routing, frame weight, frame utility. I want a 3D frame. Titanium, of course. Passive rear suspension, split seat stays for a belt drive (or a split dropout), T47 bb, the works. Exciting times.

Not sure what that frame has solved, except complicating the heck out of it.

I agree, a lot of potential for some very special machines with this technology.

^ yep, that's how my tiny brain sees it too.
