More parts, and bigger negative numbers in my bank!
The belt is absurdly light.
I don't know the weight of the Phil Wood Cog, but I'm guessing it will even out in the weight savings department. It's quite amazing though; I hope it is just as strong and durable as they say.
The saddle is pretty nice. I can't put it on any other bike though, I dont' want it molding to my butt with out being fitted at the shop. Pretty sweet little bag too.
