Good, thoughtful replies. Keep 'em coming. I've not experienced any discomfort on my stock Trek 2300 since purchase last fall (55 mi longest ride, 900 total mi). I've got fairly big hands, and my stock handle bar just feels too skinny for long-term comfort. I also realize some comfort items decrease efficiency. I've been riding 100 psi and a couple of people have advised me to run a bit higher, which I may. Also, when the weather improves, I'll start using my new Shimano carbon shoes. Hopefully the improvement in efficiency won't come with a significant discomfort price tag.

Also, I noted last night when reading latest edition of Outside magazine that the K-Wings were promenently featured on a new Cannondale in their bike review article.
