Keen followers of spokemagazine.com got a sneak peak a month back of Crank Brothers' new adjustable height seatpost the Kronolog (that was before we took the post down at Crank Brothers' behest; turns out it was a leak). Now a month later it's all official. Hopefully we can get our hands on one to test soon. I'm still using the Joplin 4 on my Tallboy and with tender loving care it's been going well, but a five inch version would be very welcome. Oh I just spoke to the distributor and we should be seeing the Kronolog sometime mid to late April. Full press release spiel below.
Since Crank Brothers has been in the adjustable seatpost category for nearly five years, we have learned a lot about what works. With that knowledge, we decided it was time for a better approach. With a fresh set of eyes, we designed a post that we believe in. It is technical, durable, and beautiful. Introducing the Kronolog.
The mechanical design of the Kronolog allows for very accurate, precise movement. It has 5-inches of travel, and is the only mechanical post that is infinitely adjustable. It is even possible to reduce the travel of the Kronolog in 20mm increments simply by adding a spacer. Although it functions mechanically, the Kronolog feels hydraulic. It is smooth, supple, and quiet. Air spring technology lets you adjust the preload and return speed simply with air using a standard shock pump, and air damping allows the saddle to return to a normal riding position in two, smooth stages.
The Kronolog has a unique keying system between the quill and shaft that virtually eliminates rotational play. It also locks into position both upward and downward. Improved cable routing means that the cable will not interfere with your riding - the cable routes from the post's stationary body, so when the post moves up and down, the cable does not move.
The Kronolog seatpost is a very simple design with a limited number of functioning parts. Fewer parts means fewer failures. The Kronolog passes 2.7 times EN fatigue testing, making it twice as strong as other adjustable posts on the market. The Kronolog offers more travel, durability, and robustness, all at about 50g less than the previous Crank Brothers adjustable post. It is stronger and lighter. The Kronolog sets a new standard for adjustable seatposts.

"For trail riders, the drop post is one of those products that drastically improves the ride, regardless of genre, travel, or wheel size. It's worth its weight in gold, and once you try one you never go back. Crank Brothers has been in the drop post game from the beginning. The Kronolog is something we've been working on for quite a while now, and it's the evolution in adjustable post technology. I've been thrashing the Kronolog for months in different conditions, environments, and applications, with no play or failures. This is refreshing because I'm not a big fan of bleeding my post after a failure on the trail. It's packed with features and refinements and is by far my favourite drop post on the market. Take one for a spin and you'll understand." - Chris Van Dine
"I am not willing to compromise on a good descent, and the Kronolog post does what it's supposed to do. The feel is smooth and consistent, plus reliable in all conditions. Adjustable posts make riding more fun." - Jill Kintner
"It's been a couple years of testing the Kronolog, and I'm happy with the many added benefits, like more adjustablility, less weight, better cable routing options, no saddle wiggle and a sleek look." - Hans Rey
