Clinchers for Pave, gravel(7 posts)

I'm going to promote a race in the spring that will mimic in a small way the spring classics in Europe- we'll have brick streets (not actual, pave, OK) and country roads including some lanes with gravel, other roads that are paved with the gravel chip and oil method. Some roads will be smooth pavement. There will probably be 15% of the course that is not smooth pavement.

What would you recommend for a tire that works well in wet and rough and sometimes loose conditions? Is it worthwhile to go to a 700 x25 versus 23? Clinchers only- that's my wheelset. Cheaper the better of course since it will be specialty use, not general season-long racing tires. I have tried Michelin Axial Pros (i know, they won Paris-Roubaix) but I don't have a personal team car to do the wheel change in 15 seconds.

I would highly recommend the personal team car. Having one last year shaved seconds off my average finishing time.

Where are you promoting this race?

In my riding in NH, which includes alot of dirt roads and super rough pavement, is that continental Grand prix 3000 in a 23 works great, Have not had a puncture on any dirt roads in 2 years with them.

I'll have to give those tires a try if they hold up in new England. I'm originally from NY state a bit west of Albany, rough farm country, and know exactly what you mean about the type of roads.

here in Colorado is run on rutted, washboard dirt, sharp gravel, etc...- no pavement. It's a big spring race here, and everyone I saw used road bikes with standard 23mm slicks / clincher wheels. Not a race to bring your trick light carbo set to, but the standard equipage seemed to hold up (mostly) fine. Sure, people got flats, but it's a fast, hardpacked course for the most part, and a fatter or heavier tire creates too much disadvantage.

Have you heard of Prairie Roubaix, "The Heck of the North"? Its an annual race run in Minnesota, over several types of terrain (pavement, dirt, gravel). Have a look at:

There used to be some photos up, but I can't find them. I'll bet that someone from the GIS racing team could give you more info about running a race like this, along with what equipment they recommend.

I really, really wanted to do that race this year. I scouted the course and mounted old 25mm specialized armadillos (which measure as 27mm on my bike) alas the race was cancelled because a section of the course was flooded...i would have still rode...For the race in question i say that if the roads are not muddy and just rough run standard tires at 10 psi below normal. 25 mm at most, at the same, lower pressure.
