The Review
I needed a 400mm, zero offset seatpost for my new bike, and this was the only one at the shop that fit my requirements (and it was on sale too!) It was my first Crank Brothers product, and the first higher end seatpost I ever bought (I have always used stock oems, or the cheapest possible ones).

The craftsmanship is simply beautiful, but I had never-ending problems with the clamp bolt. I found that the single side bolt was unable to provide consistent clamping force on my saddle rails, and my saddle would repeated slip when I'm riding my bike. No amount of tightening would solve this. At one point, I tightened the bolt so hard that I snapped my wrench, and my saddle duly slipped again a few hours later. Because of my experience, I am now wary of all seatposts using this particular clamp.

I replaced it with a Thompson Elite, and have not had any problems since. I should also note that all the cheap seatposts I have used over the years have been problem free as well.

DO NOT GET THIS!!(unless u want to hang it on your wall).
