So I'm really liking the idea of a leather saddle the more I read about them. It looks like with my outside sit bone measurements of 180, I'd be needing about a 200mm width saddle... that's squarely in the touring realm. Since I've had success with cutouts, I'm thinking B68 Imperial. I like the look of the Rivet Pearl as well, but at 170mm I'm not sure if that'd be wide enough even in a drop bar position. I would be centered, but my outside edges would be well off which is the problem I have now with my Specialized 155. Looks like Wallbike doesn't have the B68 Imperial right now, but maybe I can find it locally (with a reasonable return policy).

It really doesn't matter to throw a "touring" seat on a road bike? I suppose the Lexa doesn't really have aggressive geometry, and with a goal of riding the STP that's essentially touring right?

I just keep thinking of my mom's step through mountain bike with a big cushy neoprene Serfas that feels like you're sitting on the sofa... no wonder she doesn't like riding her bike!
