Love the audio example. Aluminium certainly doesn’t sound comfortable.

More science!
TIRE ROLLING RESISTANCE

Funny thing, I’ve seen a lot of people switch to “low rolling resistance” but inflating them too much and ending up worse.

man that is a total thread hijack

man it freaks me out that a bad tire choice can cost you TWENTY WATTS

To be honest I can’t really feel any “real world” difference between the three.

I feel relieved that I finally got that off my chest.

i don’t ride enough stuff other than aluminum to say, but the kind of roads you tend to be on could make this kind of affect much more or much less apparent, I imagine.

and a nice soft tire too

You must have forgot this video of the wind tunnel results from the tests…what could be more clear?

twenty watts? or forty watts for front and rear…?

  1. Does his model for input response shown in the latter portions assume equivalent structure stiffnesses? We need more detail on that part…that might not be a valid assumption IMHO.

  2. It’s not so much the material, it’s what you DO with it that counts :wink:

  3. If high frequency vibrations are making it to your frame, your pneumatic tires aren’t doing their job (either due to them being crappy tires or you pumping them up too high).

You mean my solid rubber tires aren’t as good as pneumatic ones

Depends on the rubber and the surface ;-)…but, in general, no…of course, I have a feeling that was somewhat of a rhetorical question, huh?
