Well, he discounted air drag from fatter tires; but I think I find that
fatter, and taller too, tires slow me down in a strong headwind compared to
28s or 32s.
And big fat 29er knobbies definitely have more wind drag in headwinds!

Jan's testing method involves actually riding down a road, so air resistance
should play into his results - at least at testing speeds (wind drag rises with
the square of velocity) - which is another reason to trust his results more
than those from a smooth, stationary roller.

Actually 3 questions, if we add the "where to stop adding more suppleness
to an already supple tire?".
I absolutely agree with your statement regarding the esoteric nature of the
perceived handling differences between wheel sizes simply due to the fact
that the absolute judge of what feels best
Yes, the benefit of casing suppleness is principally lower rolling
resistance, though I find that more supple tires are also more comfortable
at a given tire pressure (and, OTOH, that they often require a higher
pressure to avoid sidewall flop than do tires with stiffer sidewalls).
We've got 2 que
And how much he or she cares about that difference

The principal benefit of the greater suppleness is reduced rolling resistance,
reduced hysteric losses and thus greater speed for the same watt input.
The real question though is at which point we have diminishing returns. I dont
think that this is a one-answer-fits-all as I believe its greatly
Yeah, but his tests were to my judgment not conclusive. How do you "prove"
that this handling is better than that? And for whom? Once again, my own
experience, which is extensive, if not as extensive as Jan's, contradicts
this opinion.
The principal benefits of the extralights is not weight, or pr
I have several compass tires on various bikes. All standard casing. Very
pleased and frankly spoiled by them. Love supple tires!

Yes he did and he included a series of his tests in BQ to back up the
claim. I dont think JH is alone on the assessment of the 32s being optimum
size for 700c wheels. Another who comes to mind is Mike Kone of Boulder
Bicycle.
I am of the understanding that sizes beyond that are focused more in
I was just looking for a similar tire for my wife's bike. The compass
tires were all sold out, and I thought she might not appreciate tan
sidewalls. So I went with Schwalbe Kojack, 700x35, folding tires, which
weigh a respectable 330 grams

I ride Rat Trap Pass 2.3" tires on my mtb commuter. In addition to greatly
reducing vibration/shocks, the lower pressures enabled by such large volume
greatly reduces the likelihood of flatting. I regularly roll over broken
glass on my RTP's that would have pierced the 28mm Marathon Supremes on
Hi,
I use the extra light 38 mm on my Hunqapillar. I could use the 42 mm, but
they came on sale after I bought the ones I have. Which means I have used
them for about 10 months now and had no flats at all. I weigh above 110
kilos or 245 pounds and I ride on both gravel roads and asphalt. I have
Jan theorizes that there is an optimum diameter -- and absolute number --
for optimum handing, and that this correlates more or less to 622 X 32, 584
X 40 or 42, and 559 X 50.
I don't buy it, since the best handling bikes (thanks again, Grant!) I've
ridden were designed for 559 wheels with tires r
I remember Jan saying something about 32s being the optimal size for 700c on
pavement. I can fit true 38s under my fenders, but perhaps that would be better
suited to dirt or gravel. Or has the thinking moved on since then?

I use the standard casing Bon Jon 35's on my Riv commuter. Haven't seen the
need for the extralights, particularly while commuting.
Another good choice is the Soma Supple Vitesse at 33 or 38 mm (Panaracer made
clincher tire with tubular sidewalls, also offered in standard and extralight
casings)
I ride Barlow Pass ELs under fenders without a hitch. I haven't flatted
yet but I also didn't use that wheelset for my commute. Commuting (also
less than desirable roads) I used 40mm Mondials under fenders also with no
clearance problems. I REALLY like the Compass Barlow Pass tires. I was

I agree. Having used both I have found that the riding difference is very
small between the two so I have zero problem saving some money and getting
the standard casing. I have a set of light casings on my Roadeo. Unless
someone is really concerned about weight I would actually suggest saving
For reference, I have 35 mm Hypers on there now. I use 32 or 35 Supremes
under fenders in the winter.
