A true game changer in how you can descend. It’s just the right amount of drop, allowing you to pedal transitions while having the saddle out of the way when things get rowdy.

40mm of drop

In line with the ethos of our gravel products to provide more confidence, the 40mm of drop puts a rider in a more comfortable and manageable position to descend faster. Similarly, by limiting the amount of drop travel to 40mm, we maintained a saddle position that still pedals efficiently in a dropped position for short periods of time.

Inverted Design

The inverted design of the G Series Dropper Seatpost delivers greater reliability, longer service intervals, weight reduction, and a best-in-class stack height. The class leading stack height is achieved by designing the post to position the dropper’s cartridge to extend up between the saddle rails. This means that many riders who couldn’t fit a dropper post on their gravel bike due to limited seat post clearance will now be able to take advantage of the benefits that come with adding a lower center of gravity to their gravel experience.

Serviceability and Reliability

Incorporating premium grade bushings, brass vs plastic anti-rotation keys, and a high-quality gravel-tuned, fully sealedcartridge, the G Series Dropper Post is designed around simplicity tooffer the durability required for the abuses it will endure. While service intervals and requirements will vary rider to rider, new life can be breathed into the dropper post via new seals and bushings. In the instance that a worn-outcartridge needsto be replaced, you simply pull the old one out and drop a new one in. No air, no oil, no mess. Function-first simplicity at its best.

From The Journal


The gravel around our backyard Wasatch Range inspired the idea of a dropper post for fast and technical descents. It proved to be just as useful out in the Flint Hills of Kansas as well, when pedal efficiency was demanded, but where short and steep descents proved to be just as technical. In line with the ethos that our gravel products must provide more confidence, the 40mm of drop puts riders in a more comfortable and manageable position to descend fast with more confidently. The unique design allows for a more reliable and serviceable cartridge mechanism in a 27.2mm package. Similarly, the placement of the cartridge makes for a post that can be cut to the desired length for a potential weight loss of 50g from the initial 395g package. For bike packers, this inverted dropper allows for any saddle bag, of any size to be fit without any special brackets or attachments. Finally, with 25 degrees of saddle tilt adjustment, and shims included for 30.9mm and 31.6mm seat tubes, the G Series Dropper Seat Post is compatible with a wide variety of gravel bikes. Additionally, the dropper post is an excellent choice for XC riders and racers looking for a lightweight short-travel dropper post solution. The dropper post is compatible with cable-actuated remote dropper levers.
