Road Racing Tires - Opinion Request

Churchill

Hello,

I have a road bike with 700 X 28 tires.

I need new tires, what are u recommending for thin racing
type tires. I go cycling on Sundays with a club about 100 km
both flats and hills. I know there are allot of tire
companies out there, so I could use a hand before I order
them or go looking for them.

Thank you

I'm 6'2" ~175lb and ride 23's at 120 psi. Prefer Michilin
Hi-Lite's or Carbons, avging 1000 miles per puncture
(knock wood) When I rode on Hutchinson Carbon Comps I got
a flat almost every time out, as I've been informed, due
to my higher weight. They apparently serve riders ~140 lb
much better.

You will not go far wrong with Michelin Pro-Race. I use glue
ons myself, but Michelin, whether glued or wired on, are
exceptional value for money.

If you are keeping up with the club rides, why do you want
to change? What don't you like about the present tires (what
*are* the present tires?)? What are you expecting to get out
of thin tires?

I really like Vredestein Fortezzas. Right now I have 23mm,
but the next set will be 25mm.

What would be the difference between 23's and 28's ??

What does the 700 stand for ??

700 X 28

Thanks

Hi,

I was on my second set of 700 X 28 and they needed to be
replaced. I picked up my bike today and they had 700 X 28
Continental GatorSkins. I noticed they were a little wider
than my previous 700 X 28s, so I thought I would ask here on
the newsgroup.

Subsequent to my first post, I have gone to three
websites, Continental, Michelin and the one you posted
above. I believe I should have gone with the 23mm or
perhaps the 25mm's.

Oh well, it is to late to change now, perhaps next year.

Is there a significant difference between these sizes for
Sunday club cyclists ? Would I notice 'significant' less
drag and more force ?

Cordially

Stick with the wider tyres. They will be substantially more
comfortable on any sort of bumpy road and very little
slower. They will also, on the average, last longer.

Suggestion- maybe repost with a more specific subject line?

Again I'll ask- what makes you think this? What have you
been hearing or reading to make you think that 23s are the
way to go?

There are a lot of equipment things in the bike world that
seemed to be based primarily on either 'that's what everyone
else uses' or 'that's what professional racers use.'
Sometimes these are great answers- let others do the user
testing and I can benefit from their experience without
spending tons of money. And sometimes they are horrible
answers, as idiotic as looking at a FoxNews call-in 'poll'
to decide what you should think about an issue.

>Oh well, it is to late to change now, perhaps next year.

If you can afford it, nothing wrong with having more than
one set of tires. An idea- ask someone on your club ride if
they have an old set of 23s that you could try. Many regular
bikers develop a collection of tires that are near the end
of their life but they can't bring themselves to throw them
out. Or ask at the bike shop- people will come in to get new
tires put on and not care about the old ones, and some of
them are in fine shape. They might sell you some used ones
for a few bucks apiece.

What do you consider significant? To some people four
seconds over a 30 mile time trial is significant. To some
people flat tires are the biggest drag going and a fatter
tire can reduce them.

I'm not a racer and not up on all the aerodynamic and
rolling resistance issues. Somewhere there must be tests and
solid info on these kind of questions; again, maybe a more
specific subject line will draw out more technically
sophisticated people.

There are tests, although I don't know the addresses to give
you a link, off the top of my head. However, the result is
that, for a given tire construction and a given pressure,
and all else being equal, a _wider_ tire has _less_ rolling
resistance than a narrower tire.

Of course, often all else is NOT equal -- you may look at a
28 that's good for 90 psi and a 23 that's good for 145 psi,
and if you intend to inflate to the rated max, then the 23
will probably have less RR.

OTOH, if you're looking at a 28 and a 23 in the same brand
and model of tire, both with the same casing and pressure
rating, and again you intend to run at the same pressure
regardless of tire, the 28 will have less RR.

RR (at least in slick tires) comes from the casing having
to deform to allow the contact patch. Since, at 100 psi, a
tire with 100 pounds on it will have a nominal 1 square
inch contact patch, a tire with inch-wide tread will have
an inch of it's sidewall required to flex, while a tire
with a half inch wide tread will require two inches of it's
sidewall to flex.

You can read all day about it with groups.google.com.
Realistically, if you've been happy/comfortable with your
existing tires, I'd say stick with them.

Fred: 700x28 (or even 25) Cool: 700x23 (or 21 if you are
140lbs or smaller)

You're welcome. Ken
