Crankbrothers Kronolog 30.9

I used this post for about 3 rides before switching to the Thomson dropper. It functioned perfectly, the sole reason for the switch is that I couldn't get the clamping system to work on my Selle Italia oval rails properly. If you have round rails or certain other oval rails, this is a great post. I really really like my saddle and I have the some one on all of my bikes, so I didn't want to deal with getting a new one that would work long term. Included is the orignal box and complete sets of both the round rail mounting system and the oval system (which only works on certain oval rails).
