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 am quite happy with SM+ for Chicago city commuting. I hate flats, and I
don't get any.

As far as I am concerned (personally), this issue is closed.

And unless there is a significant price difference. Though the
recommended retail price is about the same for the Schwalbe Marathon
Plus and the Bontrager Satellite Elite Hardcase, from the discounters
the Bontrager was about 60 per cent the price the last time I looked.
As I have both and cannot for the life of me see any significant
difference, a 40 per cent price difference would have to feature in my
decision.

I have Schwalbe Marathon Plus on one of my TREK 520 bikes and
Bontrager Select K (with a kevlar strip inside) on the other. Both
have worn well with minimum flats. *The Schwalbe's have gone about
10,000 miles with just two flats. *The Bontrager rear tire wore out
more quickly than that but still wore longer than most tires, and with
only a couple flats. *I'll replace the Schwalbes before my next long
ride this summer. *I am not familiar with the Satellite Elite
Hardcase. *How does it compare with the Select K?

I did not have good luck with thorn resistant tubes. *Several of them
had stem failures.

Using a separate Kevlar lining with a thin tube wasn't good because
the sharp edge on the Kevlar caused flats. *So I went to the Select
K. *And then also the Schwalbe's after I had heard about them.

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 he
http://www.bontrager.com/Mountain/Wh...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.

CONSIDER Conti's history in auto and cycle tires, Conti's testing and
design department v. Schwalbe's ???

thornproof tubes are deriguer. no further testing necessary

How do these compare for puncture protection, speed and mileage
against the Schwalbe Mararthon 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"...

Continental, Germany tells us the Contact Security is

"Designed for industrial applications, the ContactSecurity can
also perform well in everyday use. Its massive puncture-proof
breaker was developed to resist metal cuttings and shards on
factory grounds. In view of its tough construction, it is not a
comfortable touring tyre with low rolling resistance, but it does
effectively ward off gravel and shards on short stretches in the
city."

The page also says "The tread derives it’s superb function from a
closer look at nature’s solutions. Animal paws were the model for
designing the tread pattern and it’s surface!"

How many animals have wheels and travel primarily on pavement?

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.

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.

$25+ rear tyre without using a thornproof tube is 1+1=0
Like lookit the tyre. It is flimsy thin pathetic, a barrier of no
redoubt. Does this film need assistance.
Well, does it ???

No kidding.

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:

slicks doan have no cuts in the contact rubbah. nada.
someone will show up; "OUT TYRE is a semi slIick so its better
because...you know when you fall"
or "OUR TYRE produces more profit because the mold uses less
rubber..."

and here's Conti with fewer knobs

http://www.universalcycles.com/shopp...4&category=196

casuing, I assume, better knob surface penetration.
