Tires
As I mentioned a couple of posts ago, I've been working on a couple of tire reviews. The most interesting one is a review of a couple of Cyclocross tires. One -- Cross EVO XG -- is by Vittoria, the other -- Mezcal Cross -- is by Geax. What makes this interesting, I think, is that Vittoria makes Geax tires, but they are nothing alike. Vittoria doesn't have any mountain bike tires and Geax doesn't have any road tires.
Other than intended usage -- the Mezcal is a semi-slick, while the XG is a full knob -- the biggest difference is in the size. Both are labeled as 34c, but while the Geax measure out to 34mm, the XG doesn't. I have found this to be true of other European tire manufacturers. Continentals almost always measure smaller than the stated size, even taking the knobs into account, and Hutchinson's Cross tire is labeled a 30 but is really only 28mm wide.
Frankly, I find 'cross tires intriguing. They don't have the room that mountain bike tires have for serious knobs, but they still need to be able to grip over a wide variety of conditions. 'Cross races are run on sand, mud, hard pack, pavement, grass and gravel -- often with rooty and off-camber sections thrown in for good measure -- and sometimes that's all in the same race! The tires need to roll fast and resist flatting. Since 'cross bikes don't have suspension, the little cushion the tires give is all there is. To this end, both the Geax and Vittoria tires did well. The full review will be up in the next few days and I'll let you know when it is.
