For those who prioritize lightweight design, that was the guiding principle behind the creation of the Helium Vertical Telescopic Seatpost. That’s its calling card: theHelium Vertical Telescopic Seatpostweighs just 304 grams in its shortest version, making it the lightest among models that pass the ISO 4210 test.

After years of development, prototyping, complex challenges, and the necessary refinements, the result is a product that stands out for its simplicity, efficiency, and reliability. It was developed with competition in mind to satisfy not only the rider but also the mechanic. It delivers the immediate responsiveness that every athlete needs during a carrera. Furthermore, mounting and adjusting the saddle has become a very simple task, and the seatpost can be removed from the frame without having to disconnect the control cable.

Features:

Independent Locking Cartridge (ILC):

In any dropper post, the aluminum structural tube is subjected to very high bending stresses. Conventional mechanical-locking dropper posts have a slotted tube, which causes high stress concentrations, requiring a thick wall to compensate. Vertical has patented its own locking mechanism, which—similar to a hydraulic seatpost—allows the structural tube to be smooth on the inside, eliminating the need for locking grooves, making it much lighter and more fatigue-resistant than a grooved tube. This is achieved thanks to a mechanical locking cartridge, which handles only the axial forces.

Quick Seat Clamping (QSC): Maximum ease of saddle installation

Mounting the saddle on any seatpost has always been a tedious task due to poor access to the components that secure the saddle. The titanium nuts are captive within the upper bracket. The open slots where the heads of the two mounting bolts are anchored allow these bolts to be pre-threaded into the nuts. The entire assembly—saddle, bracket, nuts, and bolts—is thus effectively secured, eliminating the hassle of having to hold multiple parts in precarious balance. Another technical detail that users of saddles with an anti-prostate opening will appreciate is the inclusion of an Allen key slot at the end of the bolts (which is visible from the saddle’s anti-prostate opening) to facilitate tilt adjustment. This makes the assembly process much simpler and more user-friendly.

Optimal Carbon Layup (OCL): The structural tube is made of carbon fiber

Developing a carbon tube to meet the demands of a telescoping seatpost is no easy task. Not only must a smooth interior finish be ensured for smooth sliding, but the tube must also withstand the demanding stresses specified by ISO 4210 and be sufficiently rigid to withstand the clamping force of the seatpost clamp. Vertical has developed its own process to produce a tube that meets all technical specifications and also features precision grooves for smooth guidance.

This is achieved through high-precision molding for optimal movement. The layer arrangement has been optimized to maximize strength and to stiffen the tube against deformation caused by the seatpost clamp. 6Al-4V titanium is used for the fasteners and locking mechanism. 7075T6 aluminum is CNC-machined to form the remaining parts. Parts exposed to friction are hard-anodized to ensure longevity and smooth operation. Only the best materials result in a lightweight, reliable, and well-finished product.

This relieves the slotted sleeve of these bending stresses, as it operates solely in the axial direction.

Thanks to this ingenious technical solution, the amount of material required to construct this tube is minimal, resulting in incredible lightness combined with optimal strength.

The best materials for a unique product.

Easy Detachment System (EDS):

Any user of a telescopic seatpost has experienced the cumbersome process of having to detach the cable to remove the seatpost from the bike. For Vertical, making this operation easier for both the mechanic and the end user is a priority, which is why it has developed a system to disconnect the seatpost from the cable without tools. This system allows you to move the seatpost from one bike to another with great ease. All you need is an EDS kit for each additional bike on which you wish to mount the seatpost.

It is available in 30.9 mm and 31.6 mm sizes and comes in four lengths, all offering 90 mm of travel except for the shortest model, which has 60 mm of travel.
