Frame Stiffness comparisons

statto said:

Does anyone know if quantative frame stiffness data exists to compare carbon frames on a relative basis? And if so where I can see it?

www.efbe.de

From a test by German bike magazine Tour: Testing done with efbe manufactured equipment.

Numbers are ordered by 1.) points 2.) weight frame, 3.) weight fork, 4.) lateral stiffness, 5.) bb stiffness, 6.) fork stiffness

1. Canyon Carbon F10: 75pts, 997g, 332g, 100Nm/°, 129Nm/°, 55N/mm
2. Red Bull Carbon SL: 64pts, 1025g, 480g, 95Nm/°, 104Nm/°, 35N/mm
3. Scott CR-1 Limited: 62pts, 925g, 393g, 84Nm/°, 101Nm/°, 43N/mm
3. Stevens SCF 1: 62pts, 985g, 392g, 73Nm/°, 96Nm/°, 40N/mm
5. Time VXRS Module: 61pts, 1044g, 344g, 63Nm/°, 91Nm/°, 50N/mm
6. Cube Litening GTC: 59pts, 1098g, 384g, 84Nm/°, 94Nm/°, 38N/mm
6. Isaac Impulse: 59pts, 1030g, 385g, 75Nm/°, 93Nm/°, 38N/mm
8. Look 585: 58pts, 1052g, 322g, 66Nm/°, 92Nm/°, 42N/mm
8. Storck Scenario CD 1.0: 58pts, 1073g, 427g, 87Nm/°, 104Nm/°, 46N/mm
10. Wilier Le Roi: 55pts, 1042g, 392g, 81Nm/°, 105Nm/°, 34N/mm

Interesting data. As far as I know, Efbe is the only source of this kind of test info. Light weight means nothing without adequate stiffness and strength, so I'm glad somebody is at least trying to measure it.

Of all the frames listed, only the Scott is commonly available here. Our LBS brought a new CR1 to our annual club century ride on Saturday. The frame had a gloss black finish which looked great with the DA 10 sp components.

Are these the only ones tested? or are these the top ten?
