Crank Brothers Kronolog Seatpost

NOTE* This item is a return and has been installed. There are a few light scuffs along the post. This sale inlcudes all of the original packaging.

Kronolog from Crank Brothers offers 125mm of adjustment in a simple mechanical design. Kronolog is the only manufacturer that offers infinite travel adjustment. The air spring pre-load and return can be be adjusted with any shock pump using a shrader valve. Two stage damping allows the saddle to return to full height in two smooth stages.

The remote lever on the Crank Brothers Kronolog can be mounted either on the right or left side of the handlebars . At the other end, the cable and housing attach to the stationary lower part of the post keeping the cable routing from moving up and down the post and keeping the cable routing much cleaner. The central entry point keeps the cable routing clean regardless of what side your cable is routed and can also be routed from the back.


The Kronolog is offered in a 405mm aluminum post length with a travel adjustment of 125mm or 5 inches in black or black and red. The remote lever can be attached on the right or left side of the handlebars.


The kronolog was named #1 in the list of the 11 Best Cycling Products of 2012 by Outside Magazine.
"This dropper post impressed us more than any other piece of gear this year. Crank Brothers replaced the hydraulic internals of the uneven Joplin with an all-mechanical design that has stood up to nine months of hard wear. We prefer the Kronolog’s infinite height adjustment to other brands' two- or three- stage configurations, as well as the simplicity of the air spring for slowing or speeding the post’s return rate. This is not only a huge improvement from Crank Brothers’ original design, but it’s darn near our favorite dropper on the market, and we recommend it on any bike except for your lightest weight racer."

Comments about CrankBrothers Outlet: CRNK Bros Kronolog Dropper Post:

I only paid $175 for it so I'm not supper mad, but only after 3 weeks of use I had to send it back to Crankbrothers to have it rebuilt. They had no problem doing this but I had to pay shipping cost both ways. I've had It back for about 2 weeks now and it's working fine. One other thing is that this post doesn't drop as far down as others because of where the mechanics are placed. Something to be aware of when you order.
