Out of interest, z-man, how would you suggest determining what rolls faster
if you believe an empirical test that tries to minimize rider input, wind,
etc. cannot?

BQ is the second best bicycling publication that I read.
Anything written by Grant is more fun for me.
In my experience, all the perceptions and theorizing can be fun if the
conversation can stay productive and not contentious.
Folks with 'bike chops' (R. Sachs D. Brooks, along with others)
Not claim, Steve, but hyperbole. Was being cynical. With the amount of
fat bikes on the road these days, my own perception of wide tires has
changed. I now consider 26x50mm Kojaks medium narrow, and tires like 37mm
positively skinny.
See you folks around and will stop bothering the group.
Ploughing old ground.
Tubes - thin or fat.
Tires - skinny or fat.
Inflation - high or low.
This has been debated on various fora over a span of several years, till all
that remains are beliefs, opinions,
fortified positions, and boredom.
Seems this stuff needs to get batted around
Yes, I am rather sorry I posted that link -- a lot more heat than

be, hmm, interesting, click on next tab.
I think it's time to give this one a rest.

Having made one negative entry on this, let me add that on two points Jan
is absolutely right.
I've been riding Grand Bois Cerf Green this summer and have found them to
be outstanding - fast, comfortable and puncture resistant. Much nicer tire

Believe what you want to believe. If Galileo were the last word on science, it

Still so many variables there! In order to get a truly scientific test of

I keep the good ones forever.
Still have my Dave Porter custom and that's over 20 years old.
I'm keeping my Riv Custom until I wear out.
The Riv is so good I've fantasized having a duplicate made as a backup.

You're not going to determine what rolls faster by rolling down a hill and

points about the joy of riding fast, but on intelligent bikes. Several
