Ritchey WCS alloy seatposts are the finest alloy posts made.

Dependability, smooth infinite adjustment, elegant aesthetics and optimal strength-to-weight ratios are the hallmarks of Ritchey seatpost design.

Decades of research, innovation and heritage inform every Ritchey WCS seatpost to deliver posts that hit the mark, and do so with style. 

Proper bike set-up starts at the saddle. Body position over the cranks is key to minimizing fatigue and injury while ensuring efficient power output and comfort. The right seatpost can make or break bike fit, making any long bike adventure enjoyable or painful. A key feature to Ritchey posts is a wide range of adjustability, allowing for more time in the saddle, klm after klm.
