WCS Carbon 1-Bolt Seatpost

Drawing on Ritchey's extensive heritage in cyclocross racing, the WCS Carbon Seatpost brings dependability, simplicity, and elegant aesthetics to your 'cross or gravel steed. The refined carbon construction ensures a high strength-to-weight ratio, while the 1-Bolt SideBinder seat clamp eliminates the frustration of finicky 2-bolt designs. Secured by a single 5mm bolt, the SideBinder offers ease of adjustability while at the same time relieving stress on saddle rails.

Under no circumstances should you buy

I've used it once or twice and have initial impressions

This is the worst designed seat post clamp ever. I should have taken the warning from my LBS seriously. My LBS would not even take the time to put on. They said too much of a PIA. They were right. It requires two people to get a saddle attached. Finally got one but I took back off. Going to return it. I don?t want a seat post that required this much effort.
