cst tyres

[blazingsaddles]

I'm looking at replacing my standard Schwalbe Marathons (700x28c). I've no complaints other than perhaps they are a little heavy at 560grams.

Has anyone ever heard of CST tyres? I was looking at the Sensamo Firenze. It weighs in at 497grams. Here's a link http://csttires.co.uk/brochure/brochure.html

Many thanks

They used to be Cheng Shin tyres. I had one on my BMW motorbike a decade ago good value but wore out a bit quick. I dont know how long they have been into cycle tyres.

The Dutch fietserbond have been testing some of them: http://www.fietsersbond.nl/node/5907

any chance of a precis of what they said? Between the language and the cookies required, my computer isn't playing ball....

Very good

The links with the predicate "very good" tires with a low rolling resistance combined with fair to good puncture resistance, very good puncture protection with a reasonable rolling resistance or rolling resistance and puncture both score well.

Vittoria Randonneur Hyper Hyper or Voyager Folding € 42.90
37-622 B / B-SK + RT Triple Shielding
(tested under the name randonneur hyper but the name was changed in 2013 voyager hyper)

An unknown band, but a must for anyone wanting a fast, lightweight, comfortable band looking with reasonable puncture resistance. A band that you at least 4.5 to 5 bar pressure should keep for at the stootlektest Schwalbe scored poorly. Also comes in size from 40 to 622.

Results:
Weight: 408 grams
Rolling: 1 very good
Lekprikkracht: 7 well
Lekprikarbeid: 18 moderate
comfort: 1 very good

Schwalbe Big Apple € 31.50
55-622 B / B-SK + RT HS430 Performance Line, Race Guard, LiteSkin

Of the tested balloon tires the best by a good combination of low rolling resistance and good puncture protection. It is striking that the comfort at 4 bar is moderate clearly showing that wide tires are not comfortable but low pressure.

Results:
Weight: 834 grams
Rolling: 4 well
Lekprikkracht: 10 reasonable
Lekprikarbeid: 8 good
Comfort: 17 moderately


Schwalbe Marathon Plus € 37.50

37-622 B / B + RT HS348 Performance Line, SmartGuard

The Marathon Plus has a thick flexible anti-leakage layer and thereby hardly leak to get. It is schwalbe succeeded in rolling resistance despite the thick layer surprisingly low. A must if you want to drive and never leaked yet fairly light to cycling. The band is heavy and not very comfortable.

Results:

Weight: 900 grams
Roll: 14 reasonable
Lekprikkracht: 11 reasonable
Lekprikarbeid: 2 very good
Comfort: 18 moderately


Schwalbe Energizer Pro € 30.50

37-622 B / B-SK + RT HS427
Performance Line, Race Guard, LiteSkin

A band with the same rolling resistance as the Marathon Plus and also a very good puncture protection, but almost 400 grams lighter. So a tip for if you want to save weight.

Results:

Weight: 535 grams
Roll: 13 reasonable
Lekprikkracht: 3 very good
Lekprikarbeid: 4 very good
Comfort: 13 reasonable

CST Sensamo Speed ​​€ 30.95

35-622 B / B-SK + RT

An excellent all-round tire in performance between the Schwalbe Marathon and Vittoria Randonneur Hyper's.

Results:
Weight: 418 grams
Rolling: 8 good
Lekprikkracht: 4 very good
Lekprikarbeid: 12 reasonable
Comfort: 11 reasonable

Schwalbe Marathon € 27.50

37-622 B / B + RT HS420
Performance Line, Greenguard


The ordinary Marathon has a slightly anti-leakage layer thinner than the Marathon Plus. Therefore, this band is slightly faster, more comfortable, lighter but will be slightly faster leak.

Results:

Weight: 740 grams
Rolling: 9 well
Lekprikkracht: 17 moderate
Lekprikarbeid: 6 good
Comfort: 15 moderately

Good / fair

Tires in this category are just fine bands where you can have fun on bikes. But whether you're paid to a low rolling resistance and good puncture protection, one of the tires with the predicate 'very good' seems a better choice.

Schwalbe Marathon Racer Folding € 50.90

40-622 B / B-SK + RT HS429
Evo HD Speed ​​Guard

The Racer has the reputation of a fast tire. Wrongly if you look at the test results. The rolling resistance is even worse than that of the Marathon Plus. A bright, comfortable band with an almost impenetrable thin anti-leakage layer.

Results

Weight: 380 grams
Roll: 15 moderate
Lekprikkracht: 1 very good
Lekprikarbeid: 5 good
comfort: 2 very good

Panaracer Pasela € 31.50

37-622 B / B SK
Tour Guard, Kevlar

The Panaracer has the reputation of a comfortable, reasonably fast randonneurband with good puncture protection. And that is also reflected in the test. But does not score better than the CST Speed.

Results:
Weight: 517 grams
Roll: 12 reasonable
Lekprikkracht: 5 good
Lekprikarbeid: 13 reasonable
comfort: 3 very good

Grand Bois Cypres 700 € 52.75

30-622 B / C-SK

The Grand Bois tires have the reputation of being very fast and comfortable straps. I also have experience in practice and this is also evident from the test. But the Grand Bois scored no better than the Randonneur Hyper while the puncture or worse. Minimum pressure is high at 5 bar.

Results:
Weight: 290 grams
Rolling: 3 very good
Lekprikkracht: 19 moderate
Lekprikarbeid: 22 bad
Comfort: 7 well

CST Zeppelin € 26.95

50-622 B / B + RT

A cheap balloon tire with a surprising very low rolling resistance. But puncture is very bad.

Results:
Weight: 1026 grams
Rolling: 2 very good
Lekprikkracht: 22 bad
Lekprikarbeid: 23 bad
Comfort: not tested

Vredestein Moiree € 29.95

54-622 B / B + RT Puncture Resistant, OSP Compound

In terms of rolling resistance is not worse than the Big Apple. But clearly less puncture resistant.

Results:
Weight: 1119 grams
Rolling: 5 well
Lekprikkracht: 15 moderate
Lekprikarbeid: 14 reasonable
comfort: 4 very good

Moderate

Tires in this category scores at some point clearly insufficient or score on the combined rolling / puncture resistance is not good.

Continental Top Contact 2 Folding € 65.95
37-622 B / B + SK-C270 RT Vectran Breaker

A band with all the points lesser features as the Energizer Pro. But very much more expensive! Rolling fell against the test.

Results:

Weight: 570 grams
Rolling: 17 moderate
Lekprikkracht: 8 good
Lekprikarbeid: 3 very good
Comfort: 16 moderately

Vredestein Perfect Tour € 29.95

37-622 B / B + RT

A tire with a good low rolling resistance, but a remarkably moderate puncture resistance.

Results:
Weight: 663 grams
Rolling: 7 well
Lekprikkracht: 18 moderately
Lekprikarbeid: 15 moderate
Comfort: 9 good

Vredestein Perfect-E € 29.95

37-622 B / B-SK + RT Puncture Resistant, OSP Compound

The band specially for electric bicycles scores hardly different than the usual perfect tour. Just a band for e-bikes would be much better puncture resistance.

Results:
Weight: 680 grams
Rolling: 6 well
Lekprikkracht: 20 moderate
Lekprikarbeid: 19 moderate
Comfort: 12 reasonable

Schwalbe Kojak Folding € 37.50

35-622 B / B-SK + RT HS385 Performance Line, Race Guard

The kojak has the reputation of a fast tire. Wrongly because it was the slowest tire from Schwalbe from the test.

Results

Weight: 338 grams
Roll: 18 moderately
Lekprikkracht: 2 very good
Lekprikarbeid: 10 reasonable
Comfort: 8 good

CST Control € 32.95

Results:
Weight: 689gram
Roll: 11 reasonable
Lekprikkracht: 21 bad
Lekprikarbeid: 16 moderate
Comfort: 6 good

Continental Top Contact Winter 2 € 79.95

Weight: 689gram
Roll: 10 reasonable
Lekprikkracht: 24 bad
Lekprikarbeid: 24 bad
Comfort: not tested

Continental Cruise Centre € 31.95

Excessive rolling resistance and moderate puncture resistance. Clearly the worst balloon tire in the test.

Results:
Weight: 955 grams
Roll: 16 moderate
Lekprikkracht: 16 moderate
Lekprikarbeid: 20 bad
Comfort: 5 good

Continental Contact 2 € 29.95

Lekprikkracht: 13 reasonable
Lekprikarbeid: 11 reasonable
comfort: not tested

Continental Touring Plus € 35.95

Lekprikarbeid: 9 good
Comfort: 19 bad

CST Sensamo Sumo € 36.95

Results:
Weight: 948 grams
Roll: 24 very poor
Lekprikkracht: 12 reasonable
Lekprikarbeid: 1 very good
comfort: 20 bad

ooh ta!

I wonder what the difference is between

Lekprikkracht:
and
Lekprikarbeid:

?

Something to do with puncture resistance, but I'm not sure quite what; 'racht' is strength and arbeid is 'work' or something.

cheers

[blazingsaddles]

The Dutch fietserbond have been testing some of them: http://www.fietsersbond.nl/node/5907

Thanks for the interesting link. No info on the Sensamo Firenz, but some other interesting tyres.

[gaz]

IIRC my '86 Raleigh Maverick arrived shod with 26x1.75 Cheng Shin Tyres so they've been manufacturing cycle tyres for a while. IIRC I also used their hybrid style 700x35 knobblies late 80's.

I recall them being neither especially problematic, nor especially good so far as handling, wear and puncture resistance were concerned. Just another tyre.

At the time puncture resistance was in it's infancy and I was unimpressed by Nutrak's beltguard offerings.

With the evolution of Continental Top Touring and Schwalbe Marathons I haven't given Cheng Shin a second thought.

They measured both force and force x distance when stabbing the tyre, presumably because some tyres have a thin p-r layer and others a thick one.
The other thing I looked up was Stootlektest, which is a snakebite test (mentioned under the first tyre)

[Brucey]

I see, that kind of makes sense.

What doesn't make sense to me is the result where the Marathon racer was worse rolling resistance than a much heavier Marathon.

Does this make sense to anyone?

cheers

[LWaB]

Cheng Shin make Maxxis and Brompton tyres.

I don't know but the test has been performed by Schwalbe (and Continental) themselves. http://www.fietsersbond.nl/de-fiets/ond ... bandentest

You'd think they'd rerun the test if they suspected something was wrong, don't you? I'm just guessing though.

[blazingsaddles]

Yes, probably not worth changeing from Marathons for these!

Thanks

thanks for the link. I expect you are right. I followed the links on to the pdfs and both conti and schwalbe tests followed the same pattern.

What is interesting is that the tests show rather different numbers; the conti tests show the same power at 4bar pressure and 30kph as the schwalbe ones do at 25kph. This is a significant discrepancy; maybe the schwalbe tests are done with a different size roller or something.

What this does mean is that you probably can't compare Crr values from different manufacturers; you need to use independent data, or at least data from the same test equipment/lab.

cheers

[PeterBL]

I could very well expect the size of the roller to matter a lot. Are they tested with the same weight load?
