Pros & Cons

  • A lighter seatpost makes the bike feel more lively, as there's less weight to haul around.
  • The clamp is infinitely adjustable, ensuring you'll always find the right saddle position.

Weight187 grams
Saddle Rail Diameter7 x 7 mm


The Ritchey WCS Carbon 1-Bolt UD Matte seat post uses the so-called one-bolt system. This makes setting up your saddle extremely simple. The wide clamp distributes the load across the saddle rails more evenly.

The Ritchey WCS Carbon 1-Bolt UD Matte is made using UD carbon monocoque, making it lightweight, strong, and reliable. Easily adjustable and the nice finish makes this a great seat post.

Please note: the one-bolt system clamps onto the saddle rail from the side. This means you can only use saddle with round seat rails measuring 7x7 mm. Do you have a saddle with 7x9.6 mm (Fizik-standard), 8x8.5 mm (Selle Italia-standard) saddle rails, then you'll need a different saddle clamp.

lichte zadelpen maar bij montage beetje prutsen

Lichte (uiteraard :-)) zadelpen. Monteren van het zadel is een beetje prutsen. Constructie wordt met rubbertjes bij elkaar gehouden en valt snel uit elkaar. Wanneer zadel eenmaal is gemonteerd is het simpelweg bout vastdraaien en zadel zit muurvast. Als zadel geheel naar achteren wordt geschoven kan de bout m.i. makkelijk tegen binnenkant been aankomen want de constructie is redelijk breed.


  • Lekker licht
  • goed afstelbaar


  • beetje prutsen bij zadelmontage
  • redelijk brede constructie.
