It's easy to gauge traction at that spot because your rear tire slips out, and moving fore-aft doesn't make a difference. Going down the chute, you can feel how much sliding you get with hard braking. Misjudging in both cases is fairly low consequence, although a guy in my building crashed and broke his him on the chute. Then they put in non-skid, which wore off about 15 years ago. I crashed there on a pair of early Michelin colored tires with a clay based pigment. Downside of sale table finds. I can't tell the difference in traction between two quality tires -- say a Pro4 and a Conti 4000, but some sale table tires are like riding on banana peels, even after break-in. How do you like the Conti 4000? I usually use Specialized Pro but my favorite LBS is dropping Specialized so I'll have to find a replacement tire. Specialized tires don't seem to be available online. Do they have good flat protection? Grip? ... Conti 4000 are wickedly expensive and prone to sidewall cuts, IMO. Lou prefers them and can get a good deals in Europe. For me, they are always 20-50% more than Michelins. As for ride and grip, I think the Contis are a bit more plush feeling than Pro4s. I have a Conti front tire on my Roubaix; its 25mm nominal but looks and rides bigger. Oddly enough, the Conti 4Seasons are heavier and have more rolling resistance than the Pro4s and the 4000, but I really liked them on my Roubaix winter bike. They're just too expensive, so I'm using Pro4 Endurance rear tire right now -- which are good, but I don't think they are as grippy as the regular Pro4s or the 4Seasons, but that impression could be effected by the fact that it's easy to skid my rear wheel on the Roubaix because the disc is so powerful. Like I said, all the differences are subtle between the high end tires from Michelin or Continental. Thanks. I think the Conti 4000s is about the same price here as the Spec Pros that I use. I guess I'll find out shortly if I like them. I find Michelins a bit sluggish and hard to mount. Although I just watched a guy mounting a Conti in the pouring rain Sunday and he didn't seem to be enjoying it. It was a sidewall cut actually. He hit a piece of strip metal. |

So what you're saying is that a professional racing team crashed a bike and didn't replace it. I should have thought of that. No, what I said was that I believed that the majority of the CF breaks resulted from something other then a slow ride to the local shop for a bottle of milk. That's my whole point John. After talking to the company engineers at some of these bike companies I'm convinced that you can make a CF bike that would last a lifetime. But they cannot quality control every millimeter of the bikes and so they fail at a much higher rate than should be acceptable. After the way the UCI treated my communication I am quite worried that we're going to have dead riders on the course before they come to their senses. |

I guess I'll find out shortly if I like them. I find Michelins a bit sluggish and hard to mount. Although I just watched a guy mounting a Conti in the pouring rain Sunday and he didn't seem to be enjoying it. It was a sidewall cut actually. He hit a piece of strip metal. When I had my last side wall failure on a Conti Gatorskin I called my wife to pick me up with her car. I could have put a chunk of cloth in but I didn't want to go through an hour of wrestling again. Now I switched to tires with sturdier side walls. Conti Gatorskins are absolutely awesome. Winter commuting, two or more flats per week, switch to gatorskins, no more flats. They are great and also very durable. I got around 2500mi out of them on the rear. However, the side walls are so flimsy that some failed prematurely. I tried to ignore the first "aneurysm" for a while and then .... *POOF* In our area it is almost unavoidable to travel along short gravel and dirt sections during a trip and that's where Gatorskins do not fare well at all. In contrast, the side walls of the CST Conquistare I have on there now still look like new after almost 1000mi. It's just that those tires don't appear to even get remotely close to 2500mi. On the MTB the contrast between Western and Asian tires is even more pronounced. I switched to Vee Rubber and they not only have much tougher side walls but they also last longer. And cost way less. I've still got a Cheng Shin Rock Hawk to try. -- Regards, Joerg http://www.analogconsultants.com/ |

I ride Gatorskins, too, and they're relatively problem free. Just returned from another tandem ride on Gatorskins. Perhaps I should knock on wood or offer some sacrifice to appease some god, but so far, they've been perfect for us. -- - Frank Krygowski |
