Ritchey makes some of the sweetest components on the market. And their WCS series is no stranger to a clean finish line, as evidenced by Cadel Evans standing atop the podium at the 2009 World"s road race after riding his Ritchey equipped Canyon to a convincing win. One issue we"ve had with Ritchey seatposts has to do with the one bolt clamp and it"s compatibility with ovalized carbon fiber seat rails. Ritchey now offers the WCS Carbon 1-Bolt Clamp Kit. The kit consists of two replacement clamp brackets that are contoured to perfectly fit the latest carbon railed saddles -- the ones that have an ovalized rail shape. Now you can use your favorite Fizik saddle and ride in comfort and with the security of knowing that the clamp is perfectly matched to the saddle rails for a slip and squeak free connection. The Ritchey WCS Carbon 1-Bolt Clamp Kit will work on their WCS Carbon 1-Bolt Seatpost and comes in two versions -- one for 7 x 9. 6mm Fizik carbon railed saddles and another for saddles with 8 x 8. 5mm carbon rails.
