Strengths:    Looks. Matching color to other members of the Cobalt line. Reasonably light. Well made.

Weaknesses:    Price. The wedge system makes it a tad difficult to adjust angle and saddle position. The offset version does not allow for a saddle angle where the nose is pointed downward (stem blocks rails movement). Relies on a single T25 torx bolt tightened to around 12Nm to keep it all in place.

Bottom Line:   
I got it together with the Cobalt handlebar and Iodine stem, all in Iron / Black color scheme. So, I got it for it's looks. I am keeping it for it's looks too, but it gave me a lot of trouble. Finding the best saddle adjustment is a major pain with this item. But OK, one does not do that every day.

It is however well engineered, the single bolt system works when tightened to the right torque, and the bolt and nut are strong enough to hold it. So, once you get it right, it stays right.

Damn pricy though (you get stems that are just as light and infinitely less complicated for half the price).

Strengths:    Looks great, holds the saddle perfectly, dimple marker design allows for great height marking and easy adjustment of the saddle height.

Weaknesses:    A little finicky compared to a 2 bolt clamp but not difficult like other reviews make it out to be. I adjusted my saddle perfectly myself in under 1 min first time using it and it held position and has not budged!

Bottom Line:   
Great looking seat post with an interesting design and good markings for height

Strengths:    Lighter than a Thomson Elite, easier to adjust than a Thomson with the single bolt design rather than two hard to reach 4 mm bolts like a Thomson. Good looks (matches my wheels, bars and pedals). Cool marking dimple system for adjust seatpost height if you drop and raise your saddle during riding or to fit in your car.

Weaknesses:    Needed to buy a different clamp to fit my 7x9 mm carbon railed Fizik Tundra saddle.

Bottom Line:   
Simple, elegant and light. Worth the price, but I gave it 4 chilis due to the clamp needing to be swapped.

Buy if you care about weight and looks. Do not buy if you????

Strengths:    Looks awesome, Crank Bros a trustworthy name

Weaknesses:    Clamping unit really fidgety.

Bottom Line:   
Although this post looks hot, it is just too difficult to get positioned correctly. I'm really finicky when it comes to bike setup and require hours and hours to getting it to the correct millimeter. This post gave me so many problems in the setup with the saddle that I had to return the product without getting on the trail. It's okay light (243g) for its size but not worth keeping. Going back to Thomson or a Specialized S-Works Carbon if I can get a deal.

Strengths:    Very good looking. Nifty hight indication system so I can put the saddle right where it was after I get my bike out of my car.

Weaknesses:    This is by far the most fiddly bike component I have ever bought. The saddle rail clamp looks simple and fool proof enough to be a game changer. However, I think the production pieces lack the exact manufacturing tolerances required to make the clamp work perfectly, or well, or nearly at all. Adjusting saddle fore/aft position or angle requires removing the seatpost from the seat tube and having another set of hands to hold everything exactly in place while you set the clamp pieces exactly where they need to be to make the seatpost effectively fasten the saddle to your bike. It is very difficult, if not impossible, to loosen the clamp from a fully fastened position so that you can slide your saddle forward or back or point the nose skyward or down. You have to loosen the torx bolt entirely and start from scratch to get your saddle positioned exactly where you want it. This is extremely annoying and makes fine tuning on the trail impossible.

Bottom Line:   
Spend the weekend getting your saddle postioned exactly where you want it because you cannot do any fine tuning in less than twenty minutes or so. I am not sure if it was worth it to keep this seatpost instead of just returning it for something I know that has a reliable clamping mechanism.
