Really nice. Loving it.

That is pretty damn cool.

Has anyone ever seen any data for beam bikes regarding the best rear wheel for aero? Or how the lack of a seat tube compares to a seat tube used as a fairing?

Damn cool. I don't like to lust after bikes that are out of my price range but this one had me at hello.

I have had my Softride PowerWing for 14 years. It is a great bike! Eats up the bumps and my legs are fresher for the run. Very aero.
However, if you are in my age group it is a horrible bike. Do not buy one!

Wow, that's a pretty hot bike. Not too crazy about the carbon weave finish (a carbon UD finish would look way better), but I think the shapes look great. The question is, how does it really perform, drag-wise?

I haven't seen any data personally (I'm just speculating), but I would imagine that a toroidal bulge disc (like the Jet, stinger, sub 9) would be best in this circumstance as the leading edge aerodynamics of the wheel / tire would be more important than in traditional frames.

In situations that a bike has a well designed seat tube (like the P4), the trailing edge of the disc has a greater impact on drag. In this case, a flat disc performs better.

x2 says my eyeball wind tunnel

i remember reading that today's bikes seat tubes shield the rear wheel so well that "flat" discs are more aero.
this thing goes the other way, you'd be looking for a disc thats the most aero by itself.

I would rather ride this more than riding my gf.

I think you would just like a TU-TU :0) (insert pink into the TU-TU)

Nice. Seems the sweep of the down tube doesn't match the angles of the beam... But otherwise that bike looks awesome! I hope it takes off (business-wise).

What if the Hokey Pokey is what it is all about?

I'm a fan of beam bikes.

I don't love the look of the downtube on this bike...it doesn't appear to have been designed for function over form, so there's not really a reason for it to look as "odd" as it does. The contours should make some sort of sense, but they don't (i.e appear tangent to the front tire or follow the contour of the front tire or be straight). As it is, it's just sort of an arbitrary shape.

That said, I love the way the fork/headtube looks.

Unfortunately, any aerodynamic gains you get from this frame design will likely be offset by the choice of a round basebar. Come on manufacturers! Why integrate the handlebars if you're just going to add beautiful extensions to a cow of a basebar??!?!?

---

__________________________

I tweet!

The shaping behind the front wheel is pretty specific. You want enough space for air to form a boundary layer around the spinning tire (at the top maybe 40 degrees) of the wheel arc and not cause too much pressure drag. Then you want a bigger gap so that the air clinging to the tire during rotation has a little more clean air to help it separate off the back of the tire instead of continuing with the wheel rotation into the back of the fork.

So how much is this puppy gonna be? Or should I just shove my shifter into my eyeballs for even asking?

Hahahaha.... Nice... I wouldn't mind getting something like this as my 1st tri bike.... TJ's planning to have a limited run too right, I hope it's within reach budget wise...

I agree completely with DarkSpeedWorks. That is one VERY sexy bike, but the weave has to go, or at least only be an option. Offer that in matte with no weave and you'd have the hottest looking bike on the planet.

Yeah, I think TJ said around 100 will be released for 2013

Interesting, but not justification for an ugly down tube. It is obviously possible to accomplish all of those things without such an odd shape.

BL thickness would be somewhere on the order of millimeters. That is *not* why the TE of the down tube looks stupid, or why it is more crooked than the cops that beat up Rodney King.

---

__________________________

I tweet!

The BL *is* only millimeters, but you also need space for the air coming from the front that gets forced through the gap above the tire to escape. The original design images that Graeme drew that that gap too small.

Personally I don't mind the DT at all. Fast is fast, and nothing else matters...unless it makes you crash.

I rode the carbon Power-V when they first came out ('93), and then the aluminum PowerWing (first the hideous neon yellow, then the cobalt blue). Never should have sold that last one.
Oh, how I miss the comfort of those bikes, especially as I get older!

While not as sexy looking as that, titanflex is still around building bikes. If you regret it that much, try a titanflex.

I just got one a few months ago, biggest problem making mine a slow bike is the guy on top of it.

Thanks for the comments guys.

Forgot to add the price $4880usd for frame integrated fork/stem, seat post and brake set. Not to bad IMO.

God knows I am all for the small guy. God knows even better that I am a beam bike fan boy....but god also knows that at that price with out some serious wind tunnel backing that it will be a spark on a windy night.

What if the Hokey Pokey is what it is all about?

Yes will put some more photos up soon :).

I'll be very curious to see drag numbers and ride reviews of this bike.

Ummmm... bikes are cool.... this bike is twice as cool.... but I'd rather be riding my GF than any bike. What's the matter with you guys? ;) :D

Ouch. That's too much.

I just got a Shiv with SRAM Red for $4,500.

Can the maker do what all the other big names do: partner up with a carbon factory in Asia and have them make the frame? They KNOW how to weave carbon fiber. Paint it and assemble complete bikes here in the US. Then you'd have a frameset cost of around $3K and a complete bike around $4500, and you'd be able to sell many many thousands of them and make a lot of money on volume. Hell I'd buy one just because it's so cool.

Had a talk to Graeme: This is the mocked up STANDARD version of the Z1-ELEVEN. Fork will be very aero, full carbon, similar to this and will take conventional handlebar stem and front brake, and conventional groupsets or Di2/EPS. Cost will be 3200 USD for the frameset.

From what Graeme has told me these frames are very intricate and very hard to make, a frameset can take Graeme over too weeks to make! nearly every part of the frame is hand made you are paying for craftsmanship, speed and art haha and you won't have thousands of people riding around on the same bike as you! they will be very rare.

How many grams for the frame and fork?
What bottom bracket does it use?
Front or rear water bottle holder only?
Has this frame been wind tunnel tested?

Here is a photo of the frame and front end. In the early stages. The front brake is housed inside the fearings that go over the front wheel.

Will try get these answered for you.

I have one of Graeme's earlier versions that he and I call the GC-1 Concept. I bought it from Graeme in 2009, and I have ridden it in 11 IM's without a single problem.
I can speak of the quality and design that Graeme puts into his frames.
Check about my FB page (Christian Wendenburg) for many pictures, and the many color and graphics changes I have made over the years.
In fact, my GC-1 Concept is what I;m riding for IM NYC in 8 weeks.
I will try to attach a photo of it in this post (if I can get it to work).

Here is my GC-1 Concept in last year's white color. FYI: last year, I called it the NZ-1. But, earlier this year I designed and made a few modification to the frame (front derailleur mount, and beam hump cable input area). So, the frame's name got changed to GC-1 Concept.
Still, I fully believe in and support Graeme's design and build.
Like I said, I have 11 IM races on this bike, and not a single problem ever.

Those changes are exactly what I recommended to Graham when I was in talks with him about his next design iteration. You've done a beautiful job. If you ever are thinking about upgrading to a Z1-Eleven, find me and I will take that beauty off your hands. Call it the XXX-C1.

Chris

Did you do all this changes yourself or you got Graeme to do them ?

Whats is aero crudentials ? CFD or tunnel ? If its neither, its too expensive compared to its competition.

Well, I guess that IMO this could be discussed since Pearson bikes are like "haute couture" (expensive but very exclusive) compared to "prêt à porter" (nice quality and cheaper but not that exclusive).

Not so fast, the fastest aero bike in the world was designed without either of those two credentials =)

One can go a long way by just "having a clue"

Calfee can get away with that. Pseudo aero bikes which might actually make you slower can't. Not at that price. Its not 1999 anymore - customer expectations are higher now.

Good point but who still makes lenticular discs these days? Mavic and who else?

lenticular disc - Certainly not an exhaustive list, just what I can think of on short notice.

Mavic Comete Disc - http://www.mavic.com/...n/wheels/Comete-Road

Renn 555 (flat) - http://www.rennmultisport.com/~rennmem/store/commerce.cgi?product=555
Shimano Pro disc - http://www.jejamescycles.co.uk/...tubular-id43997.html

From what I can tell, only the Mavic and Zipp 900 are true lenticular shaped discs.

I had thought of those changes in 2010 after racing IM Germany. I talked with Graeme about them, but I never followed through with it more than the idea stage.
At the beginning of this year, I once again consulted with Graeme about the changes I still wanted to do. Graeme and I agreed that it would be best if I did the modifications locally due to fitment and tolerances of the stem aerobar.
I worked with my paint and body guy locally who build surfboards, and he and I got it done.
I couldn't be happier with how it turned out. IMO, I think it helps to "smooth" out the frame's shape and profile.
I have the frame torn down now, and have put new white graphics on it. Just took my aerobar to the same painter today for clear coat, then will rebuild everything in time for IM NYC.
I will post some pics of just the frame showing the differences in last year and this year with modifications.
Thanks for the offer, but I don't know that I could ever let go of this frame. It will likely become a wall trophy when I stop racing.

I talked with Nick by email about his brakes while they were still in pre-production. Unfortunately, I missed out on the pre-sale ordering for the brakes. So, I will have to wait. Plus, I want to hear how they perform from those who get the first sets.

Currently, I have Simkins Egg Brakes on front and rear, and I've been very happy with them. But, I'm always willing to look at and try new products.

---

Team Zoot-Texas, and Pickle Juice

Bmanx, he´s already got a Simkins brake on the front by the look of things. Would the Omega be that much of an improvement? Or is it just aesthetically more pleasing?

Thx

The proof is in the pudding they say so when I get mine, I will let you know how well they function. Aero is the other side of the story and I would venture a guess that when these brakes were tested they test right around the Hooker brakes but just a bit behind because the way the brake pad/holders are designed and then my gut tells me it is the Simkins brake a distant third. I am pretty sure that when Tom tested the Simkins brakes they were around the same or slightly better than the Tektro/TRP (with modified center pull) and I know how the Tektro/TRP faired in testing and that is why I sold them hours later.

Its not 1999 anymore -customer expectations are higher now.

I agree, but your use of Calfee bikes is an odd example. Calfee aero bikes always looked like really expensive Planet X clones and I never heard anybody test either type and say they were fast. I was never sure how Calfee sold any bikes at the price he charged when a P2 cost half as much and was proven aerodynamically, unless it was just the novelty value of having a different bike.

Talking about the OP bike now, I don't see how a serious consumer would pay that kind of money for an unproven design. Proven designs like the old P2C can be had now for silly-low prices. On the other hand, there is definately a component of the tri market for folks would put 'different' over performance, and some of them have a lot of money.

The example of Calfee (or maybe Colnago is a better example) is that people buy those bikes for craftmanship, brand or style, not aero performance. The beam bike is touted as a performance item so it needs in the current market to have some crudentials - especially at that price.

"The proof is in the pudding they say"

Actually, they say, "The proof of the pudding is in the eating." Sorry, I haven't been a pompous jerk yet today, and it's almost time to go home . . .

In keeping with the theme (somewhat) of this thread, I really like this bike.

I thought the problem with beam bikes was that when your thighs come parallel with the beam as they do twice every pedal revolution that it creates an air dam since the wind can't pass between your legs as the hole is filled by the beam. I think this was found in the development of the Superbike as part of Project 96. Anyone have access to this data?

I don't have any data on the superbike project of '96. But, I'm confused about the air dam effect with the beam.... The beam, at least on my Pearson is at the same height level as that of a standard geometry frame. Thus, the top tube of standard frames would create the same air dam as the thighs move into parallel position. Maybe I'm not picturing the position and effect you mention correctly?? I'm curious about your thoughts on it, but I might need further clarification so I can visualize what you mean.

A modest program of CFD analysis was carried out during the development of the Pearson Z1-11.
It may not have been the most sophisticated aero programme, but the CFD numbers for beam bikes have such a large advantage (particularly in high yaw angles) that you can afford to miss out on some of the more complicated aero tweaks. Here's some numbers for a prototype Pearson Z1, measured with and without P3 style UCI seat-post and stays
A couple of turbulence plots at 5 deg. yaw for comparison below:





For comparison, the difference between having aero wheels (disk rear and trispoke front) vs standard wheels (Ksyriums) is 5.5% at 0 deg yaw. At yaw angles of 5 deg, the disk is a disadvantage.

Graeme's new non-UCI legal canted fork also makes a 2.5% advantage, which is pretty impressive. He's been making beam bikes for quite a few years now, and he's got a huge amount of real-world data on what works.

" For comparison, the difference between having aero wheels (disk rear and trispoke front) vs standard wheels (Ksyriums) is 5.5% at 0 deg yaw. At yaw angles of 5 deg, the disk is a disadvantage. "

Are you saying that it is a disadvantage on this bike? It sure as heck isn't on any other bike I'm aware of. I've yet to see a single manufacturer or even independent test that showed a disc becoming a disadvantage with increasing yaws over a standard rim...I've seen plenty that showed the opposite though.

You're slipping up, Dev.

Earlier on in this thread, the price was mentioned (as being near $5k for the frame/fork/beam)

how flexy is it? vertically and horizontally. it looks like an awesome bike.

How did you guys determine the sizing of the bike, and can minor adjustments be made after production? It looks like it would have a limited ability to be adjusted.
