Sherwin factoid

Callistus Valer

I heard Paul Sherwin say that for wet conditions, tires
should be pumped to 65-75 psi, and when it's dry you can
even get up to 100 psi. Now I normally pump my vredesteins
to 145 psi. Is he wrong or am I?

Maybe a difference between clinchers and sew-ups?

I hear that too. I think he's mistaken. I typically race at
140-150 psi on dry conditions. I'll drop down to 100 psi in
wet conditions.

Was just a guess - an incorrect one. Oh well.

guess that's why Sherwin was a pro rider, not a mechanic :-)

Maybe it was 100 psi 30 years ago.

I too was suprised. I used to pump my time trial rear
(Gommitalia tubular on HED disc) to 140-145 psi.

You are absolutely wrong along with many other new
cyclists. That is the mark of a noob or worse, a clueless
veteran; overpumping your tires. Still, in road ITTs many
guys use up to 120 or more depending on conditions. Using
145 on the road us just stupid in most cases although I can
think of some rider\road\equipment combinations that might
benefit from this level of pressure, you are probably
following the silly tradition of using the manufacturer's
maximum burst pressure label as a "recommended" pressure.
Dumb dumb dumb...

BTW, to save time in the future you are almost always wrong.
I will let you know if you happen to get something right. Is
that a deal?

Another factoid: Paul uses no "i" in his name AFAIK. "Paul
Sherwen", veteran of 7 Tours including riding his last Tour
with Roche in 1983 (IIRC...).

Yeah they were probably solid rubber back then

It's possible that Paul is messing up the conversion from
bar to psi

If he's been looking at the 7 bar range on his pump when he
puts air in his tires, well maybe he was just off doing the
conversion for his American audience.

I noticed they display the gaps now in both kilo and miles.

That's "Sherwen." You're getting as bad as Lafferty

William Jones

Chris, IIRC, yesterday Paul mentioned riding le Tour in
1985.

Difference between today's tires and what he raced on?

I'm not sure about Sherwen, but that seems very, very
high to me.
