A question about Paris-Roubaix(5 posts)

While I've cycled recreationally for a while, only recently have I become interested in racing lore.

Slippery and treacherous in the rain, the cobbles of Paris-Roubaix seem to guarantee multiple flats and multiple crashes, giving the race a mystique like no other single day race.

My question is this: Why don't teams use special tires (tyres) and/or special frame geometry for this race?

It would seem to me that a relaxed geometry bike, somewhere between audax and touring, would make a lot more sense for this ride. And why not use 25 or even 28 cm tires on the cobbles? Or change to wider tires during the cobble sections? Is the argument that you have to sacrifice stability for speed? Has any team actually tried different bikes over the cobbles?

Most teams use 25 or 28 tires. Sometimes they borrow components from cyclocross.

I don't think the bike makes much difference. You are either a rider who can handle the mud and cobbles or you aren't. Many aren't. Ever look at how many riders actually finish the race versus how many started it? It's usually a small percentage.

I think they do run 25mm (not cm ;), and there've been a bunch of diff bikes tried at PR, including full suspention. They never won. Truth is that cobbles make up only a small %, the rest is well paved road.

Personally I commute ~50mi on dirt/gravel trail and steel road bike with 28mm tires at 95psi plus foam grips and well padded gloves/saddle is just fine, very comfy.

won with a suspension fork that appears to have abput 40-50mm of travel. In fact, Phil Ligget opined that it appeared front suspension would be the new standard for PR.

Not a fully, but he did boing.

At most, the cobble sections are a couple of miles/kilometers long. Most a lot shorter. They would be swapping bikes all the time. Greg Lemond used a front shock years ago when shocks were new on the market for mtnbikes. He was laughed at but finished very well, as I recall.
