Ritchey WCS 1-Bolt-Seatpost
Strong and lightweight post with a simple and convenient 1-bolt design, i.e. 1 bolt to adjust both the angle and position of your saddle. The post and seat gut's cradle are constructed from a single piece of forged aluminum giving it unparalleled strength and the shortest minimum seatpost insert level of any brand. All complete with elegant and classy 'wet' gloss finish.
Please note: Ritchey seat posts are not recommended for use with saddles that have carbon rails. Alloy and steel railed saddles will fit fine however.
