For those who love the lightest possible weight, that was the premise behind the creation of the Helium Vertical Telescopic Seatpost. That’s its calling card: theHelium Vertical Telescopic Seatpostweighs 304 grams in its shortest version, making it the lightest among models that pass the ISO 4210 test.

After years of development, prototypes, complex challenges, and the necessary refinements, we have created 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 responsiveness 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 needing 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-lock dropper posts have a slotted tube, which experiences 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 one. 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 the poor accessibility of the components that secure the saddle. The titanium nuts are captive within the upper mount. 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 saddle-mount-nut-bolt assembly 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 dropper post is no easy task. Not only must a smooth interior finish be ensured for proper sliding, but it must also withstand the demanding stresses required 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.

High-precision molding ensures optimal movement. The layer arrangement has been optimized to maximize strength and stiffen the tube against deformation caused by the seat 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 treated with a hard anodized finish to ensure longevity and smoothness. Only the best materials result in a lightweight, reliable, and well-finished product.

This frees the slotted sleeve from bending stresses, as it operates solely in the axial direction.

Thanks to this brilliant technical solution, the amount of material required to construct this tube is minimal, achieving incredible lightness with optimal strength.

The best materials for a unique product.

Easy Detachment System (EDS):

Any user of a dropper post has experienced the cumbersome process of having to release the cable to remove the post 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 detach the post from the cable without tools. This system allows you to move the seatpost from one bike to another with great ease. To do this, you only need an EDS kit for each additional bike where you want to mount the seatpost.

It is available in 30.9 mm and 31.6 mm sizes and in 4 lengths that allow for 90 mm of travel, except for the shortest model, which has a travel of 60 mm.
