Triestina Filante Hybrid Shimano 105 + Wilier HY-NDR28AC 2025

Hybrid Philosophy, Wilier Performance
It’s hard to believe that this bike hides a system providing electric pedal assist. Yet, it does. Filante Hybrid is an electric road bike that integrates the lightest pedal assist system in the world: the new X20 motor by Mahle, a German multinational that is driving technological innovation toward zero-impact mobility. Filante Hybrid was designed with a very specific objective: to help you go faster while minimising strain. By combining the new Mahle X20 system with everything we know about aerodynamic efficiency and by using composite materials, we have raised even further the performance of the Cento10 Hybrid, a product that has won major international awards over the seasons.An overall improvement in energy savings of practically 8%. Improved battery management and greater integration for better aerodynamics, lighter weight and better performance.

Avant-guard frame
Filante Hybrid definitely resembles the Filante SLR, the bike used by Astana Qazaqstan Team professional cyclists. There are no holes in the frame (except for the one required to recharge the battery), and the integrated monocoque carbon handlebar houses the derailleur cables and electrical system controls. The Hybrid also has the same aerodynamic carbon seat post as Filante SLR.

Built-in battery and battery life
The battery integrated into the down tube has a capacity of 236 Wh. An additional bottle-shaped battery can be on the seat post bottle holder to add 171 Wh to the system. As in the previous version, a software system and apps are available both for the user and the retailer to manage, monitor and configure the system.

New power sensor
To improve the riding experience, we have introduced a new bottom bracket with torque (power) and frequency sensor. The cyclist (through pedalling, i.e. the power the cyclist delivers) communicates with the motor via the frequency and power sensor. The system reads the “pedalling power” to modulate the assistance delivered to give the cyclist a natural pedalling experience with no jerks, sudden accelerations, or loss of assistance. For example, the motor will continue to deliver power smoothly even on steep inclines of over 10%. All of this is necessary as we move toward a cycling experience similar to that of a traditional bicycle. The power sensor (with the new firmware) also optimises battery consumption, since the power provided by the motor is much more sensitive and proportionate to the power delivered by the cyclist

New miniaturised motor
The X20 motor has been miniaturised to the max. It’s extremely lightweight (the complete system weighs just 3.6 kg for the X35 and 3.3 kg for the X20), with a modern straight pull spoke pattern and 24 spokes, a perfect match for Wilier Triestina’s carbon rims. Mahle’s new X20 motor hub delivers 55 Nm of torque, but there’s more: the body can be removed easily from the “motor” casing for easy maintenance or replacement. Shimano and SRAM XDR compatible bodies are available.

Rear thru-axle
There’s one very important detail that makes Filante Hybrid totally novel for the category: the wheel that houses the new Mahle X20 motor can be assembled and disassembled quickly, just like on a traditional thru-axle racing bike. In addition to the ease and speed of wheel assembly and disassembly, the system automatically connects to the battery, so there are no more cables to be connected or disconnected by hand. It’s all done when you insert the wheel. How? It's easy. The rear dropout has a slider with a built-in electrical connector that ensures the hub positions itself directly in contact with the battery, quickly and with no risk of misalignment.

Standard Pulsar One
Filante Hybrid comes standard with Pulsar One, a compact and easy-to-use on-board computer with a 2.1” display that updates electrical system data and trip statistics in real-time and lets the rider modify the level of pedal assistance if necessary. Pulsar One connects via the ANT+ protocol to the X20 system and to other sensors (cadence sensor, external power sensor, and heart rate monitor) and the data can be displayed directly on the screen for a more complete experience.

Total integration
The integrated handlebar is carbon monocoque and mimics the aerodynamic design of Filante Bar. However, in the hybrid version, the button and display of the new iWoc, the interface that gives access to the system and changes the pedal assistance mode, are hidden inside the handlebar stem. This unique design improves safety, since cyclists can select one of four power levels (automatic, eco, sport and boost) without having to remove their hands from the top of the handlebar. Mahle has improved iWoc’s ergonomics, ease of use and reading compared to the previous version. Cyclists can now see at a glance how much battery capacity remains and which assistance mode is selected.

Clearance & Geometries
Tire clearance is suitable for a modern road bike and is compatible with rims for tires up to 32 mm wide. Filante Hybrid comes in geometries similar to those of our endurance models. Don't expect an aggressive geometry, although the bike’s relaxed look, with a high stack and limited reach, can be deceiving. Six sizes available, from XS to XXL.
