Tire Choice for Nats(8 posts)

Tire Choice for Natsmcbaker55
Dec 11, 2003 10:50 AM
I'm considering a Michelin Mud up front with a Sprint in the rear. While the course will be muddy, I can't imagine that there will be much climbing at all. Plus, with the long pavement section on the track, a semi slick may be worth it. My biggest concern is with the off-camber sections - will the Sprint provide enough side-edge grip? What do you think?

Try them bothDwayne Barry

aren't there some designated practice times to get on the course? Take them both, and see which one works better. FWIW, I would assume just falling once on an off-camber section would cost you more time than you would make up the whole race by decreasing the rolling resistance on the rear tire by going from a mud to a sprint.

Here's why: Acceleration out of corners. Sprints will slip big time. For every second you make with lower rolling resistance on the pavement, you are going to lose many more with squirrelly handling and poor acceleration in the mud. I had a similar setup (Sprint in back, Tufo in front) for Cross Crusade Jackson Middle School race (also UCI). the course wasn't that muddy but it was slick. The Sprint was awful. Never again, I swore. There is nothing worse than setting up to pass someone coming out of a corner only to get a whole lot of nothing when stomping on the pedals (actually worse than nothing since I often got washout).

Just don't do it!

Hmmm, the course map does show numerous 180 degree corners, so you may have something there. I had Muds front and rear at Jackson and it was still pretty darn slick (at 2:00).

I expect that by your race late on Saturday (1:00 or 2:00?), the course will be somewhere between the grass sections at Jackson and Memorial -- and I couldn't imagine having had Sprints at Memorial ... I'm not going to ride at Nationals but I would have gone on Sunday at 11:00. Sunday is going to be messy!

BTW, I saw that the Oregonian is going to have a 'cross feature tomorrow. I suppose that means they might have some actual event coverage and results.

I'm racing at 1:00 on Saturday and at 11:00 Sunday - the course will be unbelievably thrashed by the end of this weekend. I agree I wouldn't have tried Sprints at either Jackson School or Memorial Park, but those races both had climbing. I think you're right about getting the power down coming out of the 180s - no place for a semi-slick.

That's great that the Oregonian will have some coverage. It's hard to imagine that they completely ignore the country's biggest 'cross series (and pretty much all cycling for that matter) right in their own backyard.

Are you going up to PIR to spectate at all? If so, give me a cheer! This is me at Jackson:

we had an off camber muddy grass section at our last race and the sprint would sink and then spin and slide. was faster to run the section than ride on that tire. lots of time and momentum lost trying to ride that section on that tire. Prefer the Tufos over the Michelines in sticky mud as it has more open space to shed mud.

Much like our local news, all that matters to the Oregonian is the Blazers. That, and high school football.

With the Cross Crusade series pulling 60-80 riders per class week in and week out, you'd think it would get a little attention.
