Ritchey WCS Streem V2 Saddle
The WCS Streem saddle is pretty much the identical cousin to Ritchey's top shelf WCS Carbon Streem. It uses the same 35 percent carbon composite shell with vibration muting Vector Wing design, the same superlight high density foam and measures out to the exact same dimensions- 275mm long by 140mm wide.
The differences rest in the rails and the cover. The WCS Streem uses titanium rails and a genuine leather cover as opposed to carbon rails and a synthetic Lorica cover.
True that adds up to a 67g weight penalty but the Ti rails mean the WSC Streem is durable enough for road or mountain use and the lack of carbon rails mean you save a nice hunk of cheese.
