It would seem with that type of hub/lacing, at 0 yaw, the amount of spokes used would have less impact.

re: pix...that puzzled me too, and then I absentmindedly tried the old ctrl-c/ctrl-v and it dropped right into a post I was working on. like this:

Sansin had some narrow hubs in the 90s, would Hooker have used those or their own?
Easton tried it a few years ago
Soul Kozak were making a narrow hub up until recently (which reminds me that I must buy one before they run out)

I actually had a patent on narrow hub flange spacing in the '90s. We did tests at the TA&M tunnel (all 0 yaw back then).

The wheel actually tests slower on it's own (a bit of a surprise), but tests faster than a standard wheel when it's on the bike (due to reduced shear between the spokes and the fork).

Wasn't it Felt that used really narrow spoke lacing? So the spokes were essentially faired by the rim itself.

And didn't they use internal radial spoke pattern (i.e. spoke elbows face the centerline)?

I tried to bring out some of the details of the frame.

Doesn't anybody else think that instagram photo looks nothing like the Cervelo marketing pics?

The way the frame is not that deep behind front wheel similar to trek kammtail.

The way the frame slopes up with a storage compartment on top and angled up looks different.

The aerobars.


Plus that instagram bike just looks shite.
yeah I thought exactly the same as you.

The Cervélo FB post has a from with kind of an x where the top tune comes up st an angle and is met with another tube from above it at an opposite angle.

That's not visible in the Instagram picture at all.

Hooker made their own. Like many CNCed (instead of cold-forged) parts of the era, they unfortunately had a tendency to break. Luckily for me, when mine did I was able to secure a blank shell from a friend who used to work for Hooker, and rebuild the wheel.

Oops, you're right, didn't read post carefully enough, was thinking of brake levers, not calipers.

It's definitely the same frame. Because of the poor level of detail in the spy pic it's easy to get confused by a graphical treatment that follows the line of the bean downwards but that's not the edge of the frame.

Aside from, yes, being a money grab, what is the incentive for companies to switch to discs? I really don't buy the safer braking bit, no one here is having trouble slowing down.


I have plenty of problems slowing down on my TT bike. Try riding a P4 in the mountains.

obligatory edit: obviously one dude who rides a notoriously crappy braking bike on a-typical roads doesn't justify discs for an entire industry, presumably they have other reasons besides braking performance


LOL!!! 2 dudes.

I'll see you, and raise:
Try riding a P4 down Whiteface. In the rain.
Before they repaved it.

I did that on 2 separate occasions.
I'm not a very smart man.

When did they repave whiteface?

I think the narrow hub was also "feature" of the original Rovals, prior to Specialized purchasing the company. The 10 lb. hub and crappy rims sure didn't help performance much though.

Kool stop salmon pads on aluminium surfaces suck ass! Might as well remove your brakes
Worst descision Tririg made was including them on the omegas. Swissstop green pads are the best u have used on aluminium brake tracks.

Don't really remember the years it was available, but I had an American Classic Speedster laced to a Mavic CXP30 back in the day.

Narrow flange, less than 70g, pretty slick bearings.

I think I saw one available on Ebay a little while ago...somebody might have some NOS somewhere.

Ah, yes, the Speedster - that's what I used for the front of my do-it-all, semi-aero wheels back in 1999, when the PowerTap hub first came out and I wanted power data at all times. The sealed bearings were too small to hold up for very long, but it was fairly easy to just pop a new set in whenever they went sour. Thanks for the trip down memory lane!

P4 is a fantastic bike ;)
Great rear brake, probably the worst design EVER from cervelo, but it still goes fast down hill

Come on. You have to admit, deep down, that you're at least slightly disappointed and you're hoping it looks better in person or with better photography.

I can actually respect the Andean. It's got an over-the-top aesthetic that works for me. Like the Lamborghini Centenario. The Omni has a nice minimalist aesthetic for me. I'll call it an Audi TT (no pun...). This thing? Pontiac Aztek?

I'll admit, I'm put off by the looks of it. I'd be very surprised if it manages to net 5w over a P5. For 5 watts I'd rather buy a new old stock P5 and go nuts upgrading the bottom bracket, wheel bearings, and derailleur cage.

I bet it will look better in person, as I find to be the case with most of these new bikes......but yeah, when seeing these spy pics, honestly this is what first popped into my head:

I'll take that wager. I just don't think Cervelo would delay and take so long and such a risk aesthetically unless it was a home run on the aero numbers. Watch and see.

Any one hazard to guess pricing on the P5x? My LBS confirmed it will be in the stratosphere, so I'm going with $12k.
