    Idea! Paris to Ancaster Tires

    I'm doing the P2A 60km for the first time this year, and I'm wondering about tires. What I read summarizes as, 'it's all road, except for the super-muddy sections'

    I'll be riding a RM Element - no cross-bike in my basement , and since this will be my only cross race of the season, I'm not buying one-time tires. Options:

    - I have a new set Michelan tubeless XCR Dry's that are my 'usual' dry-condition race tires, but I expect they'll suck on the considerable road portions. I could inflate them max and slog it out.
    - I have an old set of XCR Dry's that I could snip the center knobs off of. Never tried this, but read about it in my fav porno rag, MBA.
    - I have - call me crazy - a set of 1.1/2" slicks to bomb the roads and white-knuckle the trail. Crazy?
    - I'd consider buying new semi-slicks , but they'd have to be notably faster than my XCR Dry's on the road and still good enough to race mtb in the summer.

    Suggestions?

    Btw, I've read a few poor reviews of this race on mtbr, but my non-refundable money's paid, so I'm not skippin' it now.

    With the weather we are having, I would go with studded Nokians.
    I don't think it's going to melt my then.

    Since we have the thread going, for those of us on CX bikes what is recommended? I have Larsen MiMo CX or Michelin Mud2. If it was a dryer year I'd be heading out for some semi-slick tires like the Michelin Jets, but now I'm thinking I'll be ok with some combination of the above.

    I only did the race once (last year when the conditions were pretty good) and i would suggest that your tire choice give you more of an advantage on the road, and perhaps sacrifice some traction in the slippery parts. You can make up more time on the road. Any spot where a tire with more traction/tread will help you, chances are, that there are a lot of riders around you that will be going slow, and potentially slowing you down, so that you can't really take good advantage of your mud traction. The road sections are wide open, and with a fast rolling tire, you can go as fast as you physically can, since traffic is not much of an issue on the road sections - after the first few km anyways.
    When under pressure, your level of performance will sink to your level of preparation.

    I have used the Michelin Jets in the past two PtA races. They roll nicely on the roads, and still have good traction off-road. However, if it is muddy (which it most likely will be) I plan on using the Mud2's. My experience has been that the Jets get really sketchy in the mud. However, I won't know which tires I will be using until the week or possibly the day of the race as weather in SW Ontario can change so quickly.

    There is only 10% trail, so go with a slick tire.

    Use the baldest, fastest, lightest tire you have.

    I did the race once and most of your time is on the road.

    I was riding a mountain bike and using Hutchinson Pythons and even these were not fast enough.

    The cyclocross guys were flying on the roads, I was only able to draft them for about 2 minutes and then I couldn't keep it up.

    You can still ride a slick on the trail, just be careful, if you get passed don't worry, you will pass those knobby tired riders when you get back on the road.

    i will go with Michelin

    Jet S in the front and Michelin Mud2 in the back...

    if it dries out (which i doubt) i'll just toss Jet S on the rear as well...

    Sounds backwards to me? Wouldn't you want the grip in the front, fast rolling in the back? If you've done it before though and it worked, cool

    in this race you dont need

    front cornering grip on the dirt... you need grip in the rear to get you through...

    mud2 will be fast enough on fire roads and even asphalt - which there is not that much anyway...

    Your point about the muddy parts of the course being clogged up with hike-a-bikers is well taken.

    I'm wondering if the shaved tires will run smoother + faster on gravel road (deflect over stones at a little lower pressure) and almost as fast on pavement (the XCR's Dry's are barely 2" anyway).
    I'm going to shave my old XCR Dry's and test both them and the slicks at a local loop, Hilton Falls, where I can grab pavement, fire road and muddy single-track.

    I'll report back once I get around to it.

    Thanks, everyone!

    Info from the source on the Jet/Mud debate, taken from RBR:

    For normal log/fire road type riding when mud isn't an issue, I would just run the Jets all the time. Just as seahuston said, I run this setup in New Hampshire in the winter time on my roadie and everything works just fine.

    Do they still make the Mud or is it now called the Mud2?

    it is called Mud2 now...

    the comment from the RBR is quite basic and i believe that the guy is suggesting to run Jets in the back all the time and change the front between Jets and Mud2...

    again, i dont agree with that... although it may appear that one will get a lower rolling resistance with Jets in the back - the problem could appear in the dirt - if it is not dry. There is absolutely no traction with Jets if dirt trail sections are wet. Whatever you gain on the pavement with Jets in the back - will be lost in the dirt with lack of traction.

    if conditions are mostly dry, then Jets will be sufficient, regardless of few mudslide sections...

    which tires to use? i will rely on local guys reports couple of days ahead of the race... last year, the guy who won 40-50 masters category ran Mud2 in the back and Jets in the front - and it was not THAT wet at all... i had Jets on both wheels and had to push the bike up some, otherwise rideable, dirt climbs...

    the original mud was based on the comp s light which has since evolved into the xcr dry. that being said, if the michelin mud 2 is the tire to use for a 'cross bike at p2a, then the xcr dry is probably the tire to use with a mountain bike. whatever you use, make sure you pump it up.
    i have mud 2's front and rear. the pressure right now is 3.33 bar both front and rear. last year i finished in the top 130 and had the mud 2's pumped up to 67 psi. have since gone back on a low pressure kick.

    agreed.

    I used semislicks (1.85) and they were awesome last year.

    Most of the singletrack sections are huge bottlenecks so there's next to no passing anyway.

    Thirded, I've run 26x1.5" slicks the last couple years with great success. You need every bit of speed to stay on pace during the gravel/paved sections. The single track isn't realy singletrack anyway, and the mud is deep/thick enough that everyone is on "slicks" at the exit. Just run'em bald and drop the hammer, you'll do just fine
