Very predictable in the corners and when climbing. The front tire seems to get great traction at all times. It actually works well in wet and muddy conditions too. I turned the front tire around to go in the oppisite direction of the rear tire. The only time I lose traction is if I'm riding on the side of a rut. I had hard time finding them in the US and ended up getting them at www.mountainhomebicycleco.com | Value Rating: Overall Rating: |

The grip is ok, but I have fallen on my ass a lot more after starting using it... the speed is worth it though. | Value Rating: Overall Rating: |

from Belgium Date Reviewed: March 14, 2000 | | Duration Product Used: | 2 Years | | Strengths: | Light tyres and very fast on hardpack. Just enough grip with diamond shaped center pattern and knobs on the side. Must have for racing in dry circumstances. Predictable when cornering. Ok in sand. Rear tyre locks up nicely when braking. | | Weaknesses: | Beware when the going gets wet or on technical climbs. You have to be really good and alert to get the max out of these tyres in these circumstances. Average protection against punctures. Beware on gravel ! | | Bike Setup: | Cannondale CAAD 4 Team Volvo Full XTR, last year Cadex Carbon. | | Bottom Line: | These tyres are a must when racing on hardpack. When the track is wet, watch out or mount another tyre with center knobs (Ritchey Z-MAX WCS). On climbs they are good on all but the hardest/technical climbs where they tend to lose grip when you least expect it. | Value Rating: Overall Rating: |

And I love the red colour. | | Weaknesses: | Not always enough grip, but when the surface is hard it's the best semi-slick. | | Similar Products Used: | Vredestein grinder, IRC mythosxc slick, WTB Velocirapto, Michelin wildgripper. | | Bike Setup: | GT hardtail, RST, Kore, Plasma, XTR, Magura, Dtswiss, Mavic 517. | | Bottom Line: | Very fast tires but sometimes they just slide away and then there's nothing to stop you from falling. So it's Ride Fast, Fall hard. | Overall Rating: |

Curse these tires, I'll never be happy with velociraptors again. I too bought these cheap from performance, thought I'd give some semi-slick tires a try. Holy bejezus, these things are fast! We've had a very dry summer back east, and the trails are HARD, so these tires are kicking ass. They slide a bit more in corners, but it's predictable. I'm sure once the trails get sloppy, I'll have to take them off (sigh), or end up in a body cast. The little diamonds on the tread get excellent traction it things aren't too loose, and on the hard stuff you can here them whispering faster, faster FASTER! I'm also fairly certain they're not going to last very long. Definitely worth a try. | Overall Rating: |

I Bought a pair of these tires on sale from Performance for 19.oo apiece. At 520 grams they are lighter than almost anything you can find, and still half the price. They've handled everything that I've thrown at them beautifully, and I'de recommend the to anyone looking for a good all around semi-slick. I wouldn't hesitate to buy them again. Plus I love the yellow color. I just wish I had found them before I bought my double fighters.....these are much better. | Overall Rating: |

I ride Team Bow with a pair of Diamant Grips. Rear works very good, front doesnt provide enough grip through faster corners (mud, gravel, sand...) | Overall Rating: |

I use Diamant Slick and prefer them: very, very fast, sufficient grip, only on humid and muddy ground they loose control. Curve traction medium. It is now my fifth pair: I am happy with'em but they've only low resistance. Facit: The best good weather tire you can get | Overall Rating: |

It's a very good tire for lose sand and a forest, but it doesn't ride well in gravel. In this situation the front tire slips away, and your hint tire doesn't have any grip. | Overall Rating: |

The best tires i have tried! I was a bit sceptical first but not anymore. They roll very fast but keeps the grip anyway. A lot of riders use them here in Sweden. | Overall Rating: |

They work great. Only when the going gets really tough (extremely technical terrain) do you notice that you don't have 'real' tyres. Perfect for racing (though not when it's muddy). | Overall Rating: |

Most interesting! I tried these tires recently on the recommendation of a shop employee in Minneapolis, after tearing the sidewall of a trusty Conti Cross Country. You may have seen the Corratecs on the bike of Norwegian pro Jan-Erik Ostergaard, and been skeptical, as I was.
The Corratecs have almost no tread down the middle; there is a shallow, widely-spaced chevron pattern that extends to the sides, where it becomes more pronounced (for cornering purposes). The rest of the tread consists of just a coarse file tread (as found on a Conti Sprinter road sew-up, or on the tires on your old touring bike). I believe the Diamant Grip is a rear, which would theoretically be accompanied by an even-more-treadless front tire. I note that Ritchey is now ripping off this tread with his Speed Max, used to good success by Susan DeMattei and Frishknecht in the Olympics.
These things absolutely haul ass! I recently rode them at Chequamegon in northern Wisconsin, and also on some technical trails in Mpls., with great success. You may have noticed previously that your old, bald tires worked pretty dang well (if, unlike me, you have the patience and luck to let them get that aged before trashing their sidewalls or retiring them). These are similar in principle: the tread is only where it is needed (on the edges, to keep you semi-vertical through the turns). I had no traction problems even in loose mud, and was able to climb the rocky, rooty steep stuff in WI with greater speed and ease than ever before.
Obviously, with so little tread, these tires weigh remarkably little; they are certainly the lightest fatties I've tried (they are marked as 2.1; I'd say they are closer to 1.8-1.9), and not too expensive (I paid $30 each for folders). | Overall Rating: |
