The Kronolog looks good. But there have also been some technical improvements compared to the Joplin seatpost, which has fallen slightly behind. By pressing the remote lever in the company logo look, 125 millimetres of adjustment range is now made available via cable pull. Infinitely variable. This makes the Kronolog seatpost the first mechanical telescopic seatpost with infinitely variable height adjustment. A variant is not available, nor is one needed. The good thing is that the release mechanism is now housed in the lower, immovable tube section. This means that the cable does not have to follow the movement of the saddle and can be optimally fixed to the frame.
The Kronolog eliminates another weak point of the Joplin support: The set position is now locked. If you lift the bike with the saddle lowered, the seatpost stays where it is and does not move upwards. The non-circular cross-section of the stanchion tube prevents the saddle from twisting, but also places higher demands on the seal.
The Kronolog is now available for 299 euros for either 30.9 or 31.8 millimetre seat tube diameters, either completely in black or with a red clamp and lever. Optional colour kits in blue, red or orange are available for 45 euros each.
The Kronolog you get at Hartje (www.hartje.de) and at Cosmic Sports (www.cosmicsports.de).
Oh yes, the weight: according to the manufacturer, the 30.9 mm version of the post and lever weigh 493 grams, not including the Bowden cable and outer casing. The total weight should be in the region of 540 grams. For the 31.8 mm version, 12 grams more must be factored in.
Hans Rey explains the Kronolog and shows what you need to look out for when setting it up.
