Are they 1.125 top/1.25 bottom like the '09 595s?? I've checked their website and it does not say so even though the pictures of the 585s look like the bottom race is slightly bigger. Also, I wonder why Look didn't go with a 1.5 bottom race like Ridleys? (They do have 1.5 bottoms not 1.25 right?) I ask because I saw Ewitz's post where he said that his 585 Ultra left something to be desired in front end stiffness. From an another post by a fellow RBR'er Haydos, it seems that the 585 Ultra has one of the stiffest BB around. He put up stiffness numbers of a lot of different bike model's bottom brackets and I was surprised to see that the 585 Ultra smoked a lot other supposedly stiff as hell frames WRT to the BB deflection. The 585 U had a .26mm deflection. I find it very interesting that the Prince was at .48 and Wilier Cento Uno at .52 - IMHO, two waaaaay overpriced frames (notice I didn't say overrated because I don't have any experience with them other than my perceived value rating. Still, I know Pin and Willy defenders will flame me- so go ahead and flame away.) If the 585 U had the tapered headtube, it would stiffen up the front end to match it's excellent BB stiffness. Thoughts from 585 U riders? Anyone else feel the 585 U is not stiff enough in the front???

As for the others in the Look line, I found it interesting that the 586 was just as stiff as the 595 Originl (.03mm is negligible???) Any thoughts on this from all the Look-a-lites??

I want a 585 Ultra (or 595 Ultra, if i can ever get past the ISP) very badly!!! Like a junkie needs his crack!!!

The '08 585 still had the 1 1/8" headset both on top and bottom. It looks like the '09 still remains same dimensions (using the HCS5 fork, not the HCS6 for of the 595), but I'm not 100% sure...

The 595 is an amazing bike and quite different then the 585... the ISP really makes the entire frame feel very connected. Input is translated into action immediately.

You have to take all reviews with a pinch of salt - let me explain, if a guy weighs 200 lbs and another 130 lbs the frame will feel and ride differently or if a guy can put out 1200w in a sprint and another 800w I am sure they will both have a different feedback too also lab tests are lab tests and do not necessarily relate to road tests - I have riden a few on that list and my road feel was different to the list.

yep, you are right! i forgot to consider the reviewer's weight and power when taking into account his review of the front-end stiffness.

which bikes have you ridden that you felt contradicted these numbers? did you swap the wheels for each of the tests? disregarding the wheels if they were not the same, which frames felt the stiffest? do you think you would be able to rank them accordingly? lastly, did stiffness in the BB correspond to how fast it felt? thanks toon!
