Rated 3.6 out of 5 by 5 reviewers.
Rated 2 out of 5 by Very disappointing. I bought this because it was a decent price at £20 and it looks the part but, i have to agree with a lot of others and say that it doesn't clamp the seat rails anywhere near as much as it should do. It almost feels like the bolt will sheer or the alan key will be rounded off. It really takes a LOT of effort to tighten it up and the seat still has some play in it. It's a shame because it's a really clever design and is very light. Not what you'd expect from Crank Brothers. 04 April 2014
Rated 5 out of 5 by light enough - strong - great adjustment Light enough given the strength and length of stem. Very easy saddle adjustment 28 January 2014
Rated 4 out of 5 by Nice simple seat post Well made, quality seat post. Clamps securely, doesn't creek when under load. 04 December 2013
Rated 2 out of 5 by Big guys steer clear. I'm tall (6'4"), so I bought the 400mm version for my MTB which did come in a very pretty box. My first ride was spent tightening up the single stardrive bolt as my seat moved when I hit a decent bump/drop. The mechanism on the cobalt seat post just isn't solid enough to hold in place at the extremities of its range. Using loctite helped a little. I moved back to my shorter Gravity post whilst my search continues. 29 March 2013
Rated 5 out of 5 by Excellent Bought this as it sounded just what I wanted, being a crank brothers product I had high hopes. When it got delivered I was not disappointed, first off it comes brilliantly packaged in a display box that must cost a quid, but it all enhances the purchase experience. The post I bought was a 400mm 30.9mm and it weighs 282g, plenty acceptable, the anodizing and the markings are top quality and although the seat may seem fiddly to fit at first, being a very different clamp, it holds the saddle securely and is very simple to adjust, just make sure you have a t25 torx key. overall excwllent, would love to buy the carbon version and it's just a pity you can't choose the anodized seat clamp brackets in colours, however that does not distract from the value of such a quality item. 5 star all the way. will update in three months. 23 August 2012
