"Carbon" tires

(though I don't know exactly what 'dual' or 'single' compounds are.) The test in "Tour" deals with 700x25 tires, advantages/disadvantages over 700x23 and 700x20 tires. Not a single word about carbon black, I'm afraid. Kjell Arne -- http://www.brumunddal-sk.idrett.no/ Remove your clothes if you want to answer by e-mail! |

Maybe some of our German literate friends could lend a hand... Nothing too surprising: Advantages: lower rolling resistance at same pressure greater comfort (esp. if pressure is lowered) less likelihood of pinch flats (therefore allows lowering of pressure) Disadvantages: greater weight greater wind resistance (they question whether this is as significant for road use as on a track) don't fit in some frames harder to remove wheel with some brakes Nice to see them list which tires can be mounted without tools ("werkzeuglos") vs. those needing tire levers ("Reifenhebern") |

Excellent round-up, but I might also add that the article mentions a test done in Germany that couldn't find significant aerodynamic differences between 25 and 23 mm tires. Also note that the star rating of the tires (1-5) is for puncture resistance. Kjell Arne -- http://www.brumunddal-sk.idrett.no/ Remove your clothes if you want to answer by e-mail! |
