About This Product
The Kronolog's lowers also house an air sprung system for preload that's adjustable via a bottom mounted Schrader valve. It's obviously going to be much lighter than a coil spring, and air pressure changes also affect return/lowering speed. This simple spring makes sure it's easy to fine tune the Kronolog for rider preference, and keeps with the post's simple and light design.
The upper is oval shaped, and slides on bushings sealed from dirt inside the lower. This results in minimal saddle slop, and near zero play at the nose of the saddle. The oval shape is also essential to produce a flat surface to permit positive purchase when the locking plates are engaged.
Unlike most designs, the upper tube and saddle clamp head are forged from one piece of aluminum. This eliminates a bonded, and often creak-inducing joint between the clamp and shaft. The trend of less-is-more approach is also evident in the clamp design as well, which uses a single bolt to secure the saddle.
The post is operated remotely only (there is no post-mounted lever option), via a bar-mounted thumb lever. It can be fitted to the top, bottom, and either side of the handlebar. It uses a standard shift cable, but Crank Brothers recommends using 4mm brake housing instead of shift housing, because the wound brake housing is more flexible for cleaner routing.
The Kronolog measures 217mm from maximum insertion to the saddle clamp when at full height. While total available travel is 125mm, it can be lowered by adjusting internal spacers. It comes with all hardware and cables/housing necessary to set it up out of the box. The Crank Brothers Kronolog comes in two diametersxd4w2 30.9 and 31.6, and two colorsxd4w2 Red or Black.
