Crazy cranks... in the 80's people drilled holes in frames to reduce weight. It will be interesting to see if weight or aerodynamics are the main reason for the holes.

Astonishingly ugly crankset.

Yeah, I was looking at the cranks earlier today. Apparently they're a new prototype. Drilling: blast from the past.

Anyone else been seeing all the hooha about the S3. Apparently, the frame clearance is so tight it can only take certain models of wheel. Also, Campagnolo's new 11speed gear may or may not work with it. Seems it depends on the individual frame.

Must depend on frame size. I doubt there tolerances of manufacturing allow the same frames to be millimetres different. If they did then something would be not square by 2mm. and that would work.

Not only that, but they look like the elliptical chainwheels. Didn't think anyone used them anymore.

Apparently, that is the issue, at least by my reading of it.

He's been using them for a while. Bobby Julich was famous for using them too.

Drillings, biopace and recession. We're back to the eighties.

They're getting quite popular again. Sastre's been on 'em for a few years, and a few other Cervelo Test Team guys are on it too

These were Julich's!

Was following a guy in a sportive last summer, he had elliptical chainsets and a saddle the rotated with a short nose (if that's the correct term). I remember thinking that I had chainwheels like that in 1990 on a mountain bike Thought they had gone out with the flood but I guess I've not been observant enough

That's a French mobile number Julich's chainwheels. Haven't seen that before!

I have a Shinamo 105 Biopace chainset on my 80s road bike in the attic. They're not brillant for spinning, a bit too jerky, but ideal for climbing.

I remember my 80's "road bike". I had to ride it with one leg "through" the frame as it was too big for me Those were the days of "he'll grow into it". It didn't have an eliptic chainset (to bring this back on topic )

Sheesh, I've got Biopace on my road bike. Doesn't everyone?

jebus fricking christ. now you're monkeying with your avatar? quit it. change bothers me.

I'd actually think about giving those chainrings a go at some stage. i'm intruiged.

but the cranks and powermeter on that bike are like a huge weeping sore on the face of a very beautiful girl.

Chips Lovell

Anyway, flat bars, a mirror, and it would be perfect.

It's yellow like the Banana ! Now I am a unique Kermit.

Yeah I am suspicious of the biopace. I better not find out when I go to an ordinary chainring that I've lost my powers.

Yeah -- I hate to have to ride with what I was paid millions per year to ride with. I'm' much happier riding a 2nd rate bike and a second / third rate groupset sitting here drooling over Carlos sastre bikes. I bet he lurks around here, on this forum, laughing at all us talking more than riding.

Bunnyhopper

Flat bars, mirrors, a nice riser stem and a weeny little cable lock to keep it safe. I mean - that crankset is only $1500 but you still wouldn't want it to get nicked.

I was reading about elliptical and Biopace chain rings recently (in this) and they were saying that they didn't know of any evidence for improved performance, but you'd think there must be something if Sastre is using them.

Rule of thumb with the pros: if sponsored by someone, they will of course endorse the product. All you can say for sure is that they don't disimprove his performance.

If a rider choses non-sponsor equipment, it usually means that a.) he's unhappy with what the sponsor's providing or b.) he think's the 3rd party stuff gives him an edge.

In the case of b.) remember too that riders can be notoriously superstitious. Even if something merely feels to provide an improvement, they'll still sometimes insist on it.

You ain't seen me...

I'm dissappointed. I like my R3 SL. Simple classical lines and super lightweight. This new machine is ok, but I am not loving it, I prefer the old model. And those cranks are appalling to look at.

A good thing too. I'd hate to actually really like the new model and have to go and buy it what with the recession and all. Note to bike manufacturers, please only make ugly, heavy bike parts for a while please. You'd be saving me from myself.

As Tonto says they will ride what they are told and there is certainly the superstition factor. Rotor are a Spanish company AFAIK too, not that this necessarily has anything to do with anything but they would have an incentive to sponsor a top Spanish cyclist.

Interesting article here- Rotor and O-Symmetric work effectively in the opposite way to Biopace, in the same way as "traditional" ellipticals, effectively making the gear harder on the horizontal and easier on the verical but supposedly adressing the knee issue. Sheldon Brown has a page on Biopace here which goes into that in some more detail. BTW the excessive holes on the chainrings are to allow adjustment of the orientation of the eclipse (e.g. you can screw them on in any of those holes.) No such excuses for the cranks.

Damn -- if this were the US we could sue them

+1... a good example is that back in the early 2000's, Trek came out with a TT bike with a narrower BB (Q factor). In the wind tunnel, it improved performance by many percent, but good old Lance was slower on it than his old bike. In his mind, it was 'different' and uncomfortable, so he changed back

Very very popular in the peleton and have been for a good while. Alot of riders stopped using them though when they started using SRMs as they don't give a proper reading. Those particular cranks and rings are designed to work with the Quarg power unit you can see mounted on the spider of the cranks.

Going up?? Oh, I see, you count that as a climb...

Erm, I was doing intervals anyway. Ahem.
