Road Racing Tires - Opinion Request

Churchill said:

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.

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

What does the 700 stand for ??

700 X 28

Thanks

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.

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.

I agree - I have these in the 700 x 25 size. I can't tell any difference
in rolling resistance vs. 23s, but they sure do ride smooth, plus they are
much better than 23s on occasional dirt and crappy surfaces. I had
trouble with some out-of-round casings on these -- stay away from the
super-discount web tire deals.

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.

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.

Performance bike shop honored the web tire price and gave me the Michelin Pro
Race at the low price. I am referring to the Performance bike shop, not the
Performance web page.

On the subject of sizing: Vittoria sew-ups, Corsa EVO-CX, which fit a normal
700c wheel, we see: 21-28". What do these last numbers mean?

25s are plenty wide and are much easier to find in performance models.

5mm. Avocet make a good slick in a 700x28 (I run their 700x32), see
http://www.avocet.com/tirepages/carbon12_specs.html. Few manufacturers do,
most racers use 23s, maybe 20s or 25s. But you'll find 28s more comfortable
to ride than the narrower ones.

For what? You've rolled up a whole heap of assumptions into that one
offensive little package. Thus far the OP hasn't given a single viable
reason why he should go to 23s from his current 28s and neither have you.
