The old “cranks” at Crankbrothers know a thing or two about adjustable seat posts, and according to the company they have “learned that the main source of failure is an overcomplicated design.” They further noted that “Hydraulic posts are heavy and problematic, so we took a different route.”
That route has led to the kronolog, which was developed over a two-year process that included extensive design, development, prototyping, testing, redesigning and retesting. The company tells that this new post went through 10 design iterations, “and even more when you include incremental changes.” Through the process, the post was extensively tested both in the lab and on the trail. The kornolog promises to be infinitely adjustable and yet is designed to eliminate nearly all rotational-movement. Video after the jump
