It's cool to see people thinking outside of the box but it's hard to think that this adds enough advantages to make it catch on.

With unlimited funds, I might get one for the novelty of it.

Di2 or Campy electronic is a novelty. That's Fugly.

17.2 pounds with Boras and what looks like a minimalist saddle, and he's claiming 250 grams more in frame weight? 250 grams more than what? 250 grams (or so) is a lot of Zertz, for those who like traditional looks with shock absorbtion. Seems like he went the roundabout way to his goal :)

While there is no debating that this new concept is FUGLY as sin, the dude may actually be on to something.

He basically added a crude suspension that is very similar to "leaf springs" that have been used on the rear end of pickup trucks for the last fifty years or so. I believe even some horse-drawn wagons used leaf springs.

There is no doubt that this design is vertically more compliant than a standard rear triangle.

Depending on how effective the added compliance is, if the designer refines the aesthetics a little, this could catch on.

I'd like to see more pictures of the seat post and bottom bracket joints to see how he transitions from a single seat tube to the twin tubes for the seat and chain stays.

. . . Dave Kirk would have come up with if he'd been smokin' something when he came up with dks rear suspension. Same principle, just carried a wee bit too far.

So, would this be laterally stiff and radially compliant? :confused:

I agree on all counts. ugly, but possibly effective.

Overall I think there's gotta be a prettier way to achieve the same thing.

There's VERY few things in the world you simply CANNOT improve.

The wheel, french-press coffee, Apple marketing, and rear triangle.



Maybe they should try designing a saddle that functions like the vertebra of a Manta Ray....oh wait (http://mantasaddle.co.uk/) .

[dimsy]

terrible.

at first glance, my thought was: "why would anyone want to carry a spare, color coordinated rim, attached to their frame?"

then i saw there were no seatstays and it clicked.

"awww man, that's awful"

It must be a real PITA to measure the length of that ST...

[RPS]

I like it a lot – almost makes my frame look completely normal. :rolleyes:

Seriously, I’m all for trying different things, but at first glance and without data I expect that frame design with tubes that size has much less vertical compliance than mine. Probably less than DKS too. Ten times more than traditional frame which is essentially zero isn’t much.

I don’t see much efficiency in the layout because of the way tubes have to flex in order to gain any relative vertical movement between rear wheel and saddle. Probably also suffers from Softride drawback that distance from saddle to BBKT can change, although probably not to the same extent as Softride and other beam bikes.

It would be even more like a leafspring if he had not completed the circle and had come around from the BB area...thru the arc to the ST/TT joint and then diagonally to the DT...ending up about where DT stops/bosses live.

May have been less fugly as well.

just nasty...... :mad:

[FlashUNC]

But how does it ride?

If its a better mousetrap, I'm sure there's a market out there somewhere.

The softail is a great idea for larger bumps like those frequently encountered in cyclocross or mountain biking (as option to hardtail frames), but unavoidable friction makes it difficult to isolate small amplitude vibration that we encounter on road bikes when riding on rough pavement. I’ve found the same to be true of my Rock Shock road fork – does great job on bigger bumps like cattle crossings and broken pavement, but there is enough “stiction” to transmit too much of chip-and-seal roughness. I know the Rock Shock fork was designed for PR type of roughness, but on normal road pavement the benefits don’t outweigh the drawbacks.

For a road bike a frictionless suspension with adequate travel is hard to beat for creating smoothness IMHO.
