Conti Contact Security vs Schwalbe Marathon Plus cycle tires



http://www.specialized.com/bc/SBCEqSuperSection.jsp?ssid=Tubes

would a nice boy like pablo battani steer you wrong?

i just recently discombobulated a spec nipple neck for several miles-
like 75-without streessing the rubber.

the specs are weight and carcass comparisons not price.
A TT is in a completely different and sportier class than a Marathon.
While a Marathon or Pasela or? commutes, the TT is GT, it's a
forgiving life saving tire made commute reliable with a thicker tube.
The Marathon/Messenger class are reliable but a hassle for directional
control or stability: A loser over quickly varying surfaces: tar sand
tar sand tar on the shoulder next to traffic. That fact leads to using
a sport tire such as a Conti TT/thornproof on the front

Tire liners allow slime to work correctly with a very close mating
surface the inner side of the tire's contac area cannot give. Fluid
flow presses outward from it's hole, sealing and preventing air
release.
Liners are destructive from overlap and side edge pressures on the
tube so periodic maybe 3-400 mile tube checks at hi pressures are
necessary avoiding unpleasant surprises. Good for touring or a Tour
singular.

80mph with a 60psi tyre. Sheldon may be gone, but his work lives on:

I've never ridden a Schwalbe and so can't directly compare the Conti
Contact Security's characteristics against it.

Still, my impression after almost a winter's season's worth of riding a
CCS, on the rear wheel only, has yielded these observations: the Conti
is heavy, harsh and has a noticeably higher rolling resistance (against
the other puncture resistant tire I've had extensive experience with:
Panaracer Pasela with Tourguard). My experience corroborates Conti's
assertion that the Contact Security does not make for comfortable
riding. No flats on the Conti though, but the Pasela on the front
hasn't had a flat either.

I opted for the Contis only after efforts of sourcing a set of
Marathons locally proved fruitless -- they were a second choice to
begin with. If I could repeat the exercise I'd try harder to get my
hands on a set of Marathons instead.

The Panaracer Pasela isnot a commuter's tire. The Pasela is a niche
market around the block tire for Sunday afternoons.
The Conti Security isn't harsh, it grips loose surfaces without
resorting to knobs, louvers and gearhackles. If it didn't grip then it
would be termed harsh. You see the distinction?

Errr, not really. To me, I'd take "harsh" as "not comfortable", nothing
to do with how it grips things. My rockboots grip rock magnificently
well, but they're harsh on my feet.

I'm afraid I don't know anything about the Select K, Ron. Couldn't
find it either at http://www.bontrager.com\

The Satellite Elite Hardcase is here:
http://www.bontrager.com/Mountain/Wheelworks/Tires/5783.php
and is a triple overkill sort of tyre. From the description:
*****
Satellite Elite Hardcase
Durable, fast rolling pavement tire for long-term reliability
Dual compound tread provides long life and excellent wet-weather grip
Hardcase triple flat protection features a Kevlar belt, anti-cut
casing and anti-pinch technology
Reflex material on sidewall increases visibility at night
******

I don't know anything about thorn resistant tubes either; I count on
the Marathon Plus and the Hardcase rubber layers to keep the thorns
out, so far successfully -- no flats in reaching for 4000km between
two bikes fitted one with the Hardcase and one with the Marathon Plus.
I can recommend either, and it sounds like you like the Marathon Plus.

I use the Conti TravelContact, which is semi-slick*, puncture-
resistant and rolls well but still grips reasonably well on light off-
road. In nearly a year and 3,000 miles I've only had two punctures:
one pinch flat from letting the tyre get too soft and carrying a heavy
pannier, and one proper puncture from a very sharp piece of metal wire
that managed to get through the Kevlar.


*or, as several helpful people have said to me on the train, "your
tyre's totally worn out mate"...

And how many animals misuse "it's" twice in two sentences? I thought
the UK had something to do with the English language.

That language is no longer taught in schools as is apparent from
(lie/lay), (effect/impact), (affect/impact) and other speech
embellishments "overwhelming majority" aka "most" that we see all the
time.

Its the overwhelming majority of these kinds of things that give
wreck.bike a lack of clarity.

aka

Most of these things make wreck.bike unclear.

Dear Jobst,

Actually, its/it's perfectly clear when read aloud.

The apostrophe is helpful and even elegant punctuation on the printed
page, but its/it's utterly inaudible when you read aloud.

The same is true of they're/there/their and too/to/two.

Or John's/Johns bicycle--the apostrophe that signals possession rather
than plurality to the eye cannot be heard.

Similarly, the contraction function of the apostrophe is literally
inaudible. You cannot hear a missin' letter, even though it eventually
signals the pronunciation of can't vs. cannot

(Try to pronounce the period for abbreviation in "vs." above.)

Somehow we manage to hear things without quite so much quibbling. The
errors of grammar and punctuation on RBT scarcely ever cause even the
slightest confusion.

Cheers,

Carl Fogel

Some old fogies (me) are driven to distraction on hearing things like
'orientated'. I, for one, have learned to smile and walk away, no one
being interested in my opinions of language. Languages degrade; get over it.

Heh!

I wonder, though - how slick does a tyre have to be before it's slick
rather than semi-slick? Is there a three-quarter slick? Is the Marathon
Plus a slick:

I figure one of these day I'll roll out onto the parking lot to see a

Degrade is the wrong word. Was Latin degrading when it became Italian,
French, Spanish, etc? Was English degrading when it went from the
tongue of Beowulf to that of Chaucer's Canterbury Tales?

Oh, and I would like to point out that the olde version of the
Canterbury Tales had spotty grammar and spelling at best, there have
been many cyclic periods of sexual liberation and confinement throughout
history, and the Golden Past, whatever ideal one holds it to be, will
always be something that never was. :)

What is your methodology on that? I notice that:

Psychology: Study of Psychological matters
Mineralogy: Study of minerals
Theology: Study of religion and deities
Biology: Study of plants and animals
etc...

Therefore, consistent with the language, the word originally meant the
study of methods of one kind or another, whereas the common use seems
to be a more imposing word for method.

It's like "my personal opinion on that" aka "I believe..." but the
overwhelming majority of these long words and phrases seem to be used
to be more impressive. I'm with Andrew, for me these flourishes cast
doubt on what the writer has to say.

Sometimes it is a dodge from the fear of expressing an opinion,
because being opinionated is horrid. That's why writers often use
"hopefully you'll succeed" rather than "I hope you succeed" in order
to not express an opinion.

What a bunch of dangling adverbialism!...

hopefully
