[Closed] so ugly, it just might work...

I don't really see what the truss arrangement on the seatstay brings, looks like a lot of welding and weight for no benefit.

Looks Sick!

Yeah, I was thinking the same. I guess the idea is to stop the seatstays bending, allowing finer control over the shock characteristics?

I kinda like that...

But then again I had a KNine and thought that looked fine 🙂

Maybe, but he didn't seem to need all that for the chainstays

Chainstays aren't in compression though? Less bending force applied

If I’m thinking of the right chap, it’s probably just because he didn’t have enough larger/thicker tubing so he added some bracing to some thinner stuff for this prototype.

Also, I realise this is a DH bike but has anyone noticed THE SEAT TUBE ANGLE?!!!!

I'm gonna reckon that he's gained area to create a yoke of some sort between the LH and RH seat stays that isn't totally noodly.

Looks a bit Grim Donut to me?

It's most definitely in compression. It's pinned at each end so there will be no bending. The only reason for that truss arrangement is to prevent a buckling failure.

Let's just hope for all our sakes it proves to be an evolutionary dead end.

Looks Sick!

You do know it actually exists, ergo it's not...

COOL !!!! er .....

the seat tube angle will go to normal once theres some big fat bloke perched on the skinny saddle to compress the suspension.

All it need is a Brooks with 3 springs 😉

If I had the ability to knock frames together I'd be building stuff like this. Just for the fun of it.

I'd actually be aiming for this...

...but no doubt I'd fall a bit short.

This is his previous one, from May 2020. I think that’s the first frame he’s ever made!

I like it - I follow his stuff on instagram. This made me chortle:

Precisely the point I made earlier about buckling.

If I understand correctly, that brace is basically a prototype, he's done it that way for ease of fabrication to test that it's now strong enough, rather than wanting it to be like that

Ah, right.
