Rated 5 out of 5 by Good quality and very cool look Ordered one of these recently for my Momsen Vipa XCM bike. Everything you would expect from a Ritchey product. Looks very cool. Clean design and simple operation. The gloss finish lends itself to scratches, so not ideal for mounting post clamp bottle carrier or if you often move the height of your seat for transport or trail. Not a huge saving, but worth the money though. 03 March 2014
Rated 4 out of 5 by seguridad y lígereza Lo único negativo que los sillines que no tengan la sujeción(raíles) cilíndrica NO valen. Por citar ...la mayoría de los de carbono 09 December 2013
Rated 5 out of 5 by Brilliant - get no vibes First carbon post I have had. Had read about the difference carbon rims and bars made. So tried these and was pleased how much smoother riding was. Continuing with the upgrade to my Focus carbon frame, I thought I'd give the seat post a go. Can't express how delighted I am. Brilliant. At last the horrible vibration (although I didn't realise that was what it was but whatever it was, it was unpleasant) has gone. Oh the joy. The seat clamp is not difficult. Gives a very exact setup and adjustment. At CRC's fantastic price for a quality brand, and their and service too. Highly delighted. Recommended. 26 November 2013

Rated 5 out of 5 by Top Added this to my super six and I have to say its the best post I have ever had. Very strong and takes a lot of buzz out of the back end. Highly recommended - worth every penny! 21 June 2011
Rated 5 out of 5 by Practical and reliable seatpost For somebody having saddles with oversized Carbon or Ti rails there are Ritchey Alloy/Carbon One-Bolt Replacement Clamps on this shop. The Alloy replacement clamps are generally black and intended to use with Alloy seatposts but fully compatible with Carbon ones (just in case if you wish to see entire seatpost in black). Aside from that this is light, reliable and easy to adjust seatpost. 11 April 2011
Rated 3 out of 5 by Don't fits 8,5mm carbon rails The seatpost comes with outer clamps made for 7mm diameter rails; so they don't match oversized carbon rails having 8-9mm. 19 December 2010
