if it did

their would be cad programs to simulate truck wheels...
in the real world of actual road riding, tubes would not get subjected to these kind of forces, i could go for ti but the stuff i've ogled is SOOO springy i opted for carbon.

Eh. Pointless really. It would have been a more proper test to show the tubes in proper compression (eg, run them over w/truck while they were 'standing' up). While Im no expert, Im sure that tubes undergo laterial forces in a bicycle, but nothing in comparison to longitudinal ones.

The proper way to test tube strength would be to give Jean-Claude Vandamme a piece of carbon tubing and Dolph Lundgren a piece of Ti and let them have at it. It's more scientific that way. :rolleyes:

Chuck Norris can crush Ti tubing by just flexing his butt cheeks.

A couple of thoughts:

First, I don't know where the tubes are from. If the three tubes are actual sections from similarly priced and regarded bikes of different materials then the comparison would be a bit more fair. In fact I'd love to see that truck run over the new Ghisallo.

Second, the titanium tubing was the smallest diameter of the three, and apparently the smaller the diameter, the harder it is to crush. So it's not fair at all.

Third, like other said, being run over by a truck isn't really a real life concern, so it really isn't relevant.

That video got me thinking. Took two pieces of discarded steerer tubing, 1-1" and 1-1-1/8" and repeated the test.

The pictures speak for themselves. Guess I'm going to have to stop parking my car on my Calfee. :idea:
We may have to throw Terry's test out if he didn't use a Suburban! :^)

I can see where a few of you may have doubt's in Litespeed's testing method, I do too. Considering that they are in the south they should have placed the tubing under a pick up on blocks and rocked the pick up until it fell on the tubing. Then I could believe the results.

I was loathe to drag my Suburban out of its bag and to re-connect the battery. Looks like my BMW worked just fine though. :D

fact is, the only time my bike is at risk from being run over is when I am on it..and trust me my friends....at that point, crushing the TUBING is absolutely the LEAST of my concerns!
