My saddle came as stock with my Trek Madone 2.1 (since transferred to another frame). I believe it's a "Bontrager Affinity 1" and I'm happy with it, done rides of 80 miles+ without issue. But it's white and looks scruffy as hell,

So I'd like to replace it with an almost identical one in black, and hopefully get a slight upgrade in terms of weight too. How do I know what size saddle I have now so I know which one to order?

I was looking at the Affinity RL saddle http://www.bontrager.com/model/08801 which looks the same as the one I have but no idea if it's better / lighter or not (although that's not essential I want to change to black anyway)
