I'll Take Manhattan...(10 posts)

I'll Take Manhattan...Akirasho

(wonder how many forum users are old enuff to get the reference...)

Anywho, here is a pic of Airborne's Manhattan Project... No word (or pic) on Airborne's site outside of their forums so this may be subject to change.

As expected, it's got CF stays, but seems to be using a traditional headset and has a pump peg. Tubing appears to be fairly standard (at least from the outside) and this frame appears to be polished.

It's kinda odd... from a Ti POV, you'd have to ask the question, "Why do you need CF stays on a frame material already proported to be plush and compliant?", yet, I can see where a properly designed CF stay could be more readily tuned than metal and, everyone's doing it these days. I guess time will tell.

We abide.

Remain In Light.

Thanks for posting the pic! & CF ExplanationChris Zeller

Thanks for the pic! A lot of us have been eagerly awaiting the release of this bike, not that I've got the cash to buy one anyway.... I've heard reports that the frame is double butted as well as CF-Ti, and information about weather or not this is true?

I think the reason for CF in the rear triangle on Seven, DEAN and this frame is for stiffness. While Ti is very compliant and responsive, it has a nasty reputation of not being stiff enough in the bottom bracket. Some designs are better than others, but it seems substantial stiffness can be gained with CF. Appearently, (and I'm not clear on the physics here) the front half of the bike in Ti would retain the responsive feel and compliant ride of Ti, but the back end would benifit from the added stiffness.

Of course, how they join the Ti with the CF would be my primary concern. Can't tell from the pcture, are there lugs on the Manhattan project to accomplish this? Airborne promised to have these available after Interbike but still no info on the site. Everyone seems a bit impatient.

I don't think Zsa Zsa ever said I'll take Manhattan.

"New York is where I'd rather stay
I get allergic smelling hay
I just adore a penthouse view
Darling, I love you, but give me Park Avenue..."

"I'll take Manhattan" was a very bad Judith Kranz novel and an equally bad TV mini-series in the 1980's, No?
Ahh so...You are CorrectChris Zeller

I had "Give me park avenue" confused with "I'll take Manhattan"
It's just the seat staysRich Clark

This is a very typical design, from the look of it. The seat stays are a CF wishbone that just plugs into the main frame behind the seat tube and above the dropouts. I've seen aluminum frames like this where the join at the dropouts was secured by screws (!), in addition to whatever bonding process is used.

The rest of the frame is of standard construction. If an all-ti bike of the same design had bb flex, subbing a CF wishbone wouldn't change anything.

The reason for CF is simply that it has a unique combination of lightness, stiffness, and compliance. But it's expensive, and difficult to repair. If two frame members had the same stiffness and compliance, the CF version would be lighter than the ti version. A ti/CF frame has the advantage that the wishbone and fork, if damaged, can be easily replaced while the main frame is still a "lifetime" metal.

Airborne is obviously trying to make a high-end racing frame that can compete with anyone, while capitalizing on the popularity of these high-tech, high-zoot designs. Nothing wrong with that. We'll have to see some reviews and race results before we know how well they succeeded.

Looks like a nice bike to meDog

Sure, it may not cost $3,000 for the frame, but it looks pretty good to me. I'd ride it.

I don't think the carbon stays are there for stiffness, but rather for vibration damping.
