How to choose a bicycle seat I'll need a new saddle for my bike soon. I use it mainly for short commutes (30 minutes). About once a year I go touring for a few days, up 8 hours in the saddle.

My current saddle just came with the bike. I see there are a lot of different saddle types available now, from the ultra thin, to the wide &amp; comfy to the downright fruity.I associate the thin saddles with racers, but thats the limit of my knowledge.  

When choosing a new saddle, should I choose based on my body frame or my cycling type (i.e. get one for short commutes, one for touring)?
Choosing a saddle that fits you is very important. The wrong saddle can lead to numbness and pain in the crotch area, and in the long run serious health issues. The right saddle for you should fit comfortably regardless of what type of riding you do and will depend mainly on the width of your pelvic. Ideally you should get a professional fit. If one is not available to you, you should try a few saddles of different sizes to determine what fits you before you purchase.
