Tire recommendations for gravel/dirt road races

There are few races this spring that have be intrigued, and they are all primarily on gravel roads. One option would be to use my cross bike, but I only have knobby 34mm tires for it. The other option is replacing my slicks on my road bike with something else. Not sure what else though. I have a tubular wheel set I could use as well as a clincher.

Any thoughts?

Are you thinking about Koppenburg and Boulder Roubaix?

I haven't done B-R, but the Kopp has a fair amount of road. Your best bet would be 25mm road tires. A cross bike will be undergeared, and you'll get dropped on the paved sections real quick if you have knobby cross tires.

For the past 2 years, koppenburg has been rescheduled due to rain/snow. They said that this year they'll be holding it no matter what, so a cross bike may be the only way to stay upright if there's mud, and the hill may end up being a run-up instead of a climb on the bike.

The tubulars will be less prone to pinch flats. The Vittorias are pretty much tire of choice for the cobbled classics.

I've acutally had pretty good luck on 28c Gatorskins; do a fair amount of gravel on some of the training roads here.

Koppenburg and Boulder Roubaix are definitely a road tire courses. Ditto on the Vittoria 24mm tubulars.

Yes, I am looking at both of those races and another race out East when I visit my family. So possibly three. My cross bike would be undergeared, you are right. I am looking at the Vittoria tubulars right now - ouch, pricey. Gatorskins huh? I'll take a look.

What would you guys recommend for a red clay Georgia fire road? The Perry(GA) Roubaix is coming up and runs on the red GA clay instead of cobblestones for a portion of the race.

Gravel roads are different from place to place.

But most of the time if you're a skinny bike racer you can probably get away with tough 25's pumped up to road pressures.

If the rock chunks are big, you risk pinch flats at full speed. Only solution is bigger tougher tires.

I'd also recommend you look at gearing - a hill that you'd stand to climb on the road, might have you spinning the rear tire on dirt. So bring a lower bottom gear so you can sit and spin, if the course requires.

If you have tubular rims, get a set of the Vittoria Pave's - available in a 700x27 and put about 90 lbs in them.

Big volume tires that roll like marshmallows over pretty much anything.

Clinchers - use a 28c and just keep the pressure low enough for them to roll over things without pinching.

I raced Perry two years ago on regular 23c michelin pro2 races. No problems. But it was in the middle of a drought year and the road was pretty dry, if it rains anytime before the race expect that road to be slick as snot.

Just saw on the news that in an attempt to make professional cycling more accessible to North American audiences, the Ronde van Vlaanderen will now be known as the MS250 Ride to the Sea and Back, and that Paris-Roubaix is now the Industrial Park Criterium of the North.

What are the dates for Koppenberg and Boulder Roubaix? I'll be out in Ft. Collins with friends training over spring break 3.12-3.20.

Edit: Found the B-R date. NVM.

I did two races last year where more than 10% of the field flatted:

Bird's landing collegiate RR (Davis) had a 5(?) mile section of gravel, but it had been recently replaced, so it was not rutted out yet.

Leesville Gap RR. Looked like war-torn Bosnia (hope I didn't offend anyone. there were craters in the road). Bottles flying everywhere hands shooting up with flats left and right. The key here for me was to cheat to the side of the wheel I was following just enough to keep and eye on the road as well as the rest of the pack. I bunny-hoped and handful of massive craters that may otherwise have been pinch flats

I ran both of these races on 23c GP4000s and I weight about 175. YMMV.

So the Ronde is now a 2 day event and PR will be on a Tuesday night?

Is it on Sunday or Saturday? My teammate and I need to be back in class on Monday.

I think we are going to do the CU crit in Boulder on the 13th.

CU is the worst crit in CO...

It's both days. Are you collegiate riders? Then you can race Saturday (on a reverse course) and Sunday. If you're not collegiate you can only race Sunday.

They'll put a cone in the road about 5 miles in (I think it starts at the northernmost point and heads south first). You turn around there.

Good to know. We're going to be out more for training than racing. The two guys I'm going out there with are collegiate racers. I think what we do, as far as racing is concerned, will be decided by how we all feel. This winter has been rough for training. I know I'm certainly behind where I'd like to be.

In that case you will love cu. Easy loops, best tailgunning course ever.

Latex tubes or tubulars will also help.
