I did a search on this and came up with not quite what I was looking for.

My question: I'm a regular commuter here in Chicago and want a Brooks. I was looking between the Conquest and the Champion Flyer. I realized last night I would prefer the Flyer as it is wider and flater- better for sitting on. The Conquest is a rounder (looking from the rear) profile, narrower, and more for mountain biking, where your sitting on it less, and sliding around. The Conquest is like the Team Professional with springs, and the Champion Flyer is the B.17 with springs. Fine.

So, I want to soak up a lot of bumps, divits and other general crappiness of Chicago's streets. I want to be kind to my body so I can keep riding for the next thirty years.

So now it's between the Champion Flyer or the Regular B.17, which lots of folks have. Wondering if I'll notice a loss of pedaling efficiency with the springs, or whatever folks might think...

Muchas Gracias!

P.S. I ride a touring frame, 700x38c tires.
