Factor Sarana Disc 2026 Bicycle – Gravel Racing and Ultra-Distance

The Factor Sarana Disc 2026 is a competition gravel bike designed for ultra-distance races, endurance competitions, and multi-day adventures. Built for riders seeking high performance over long distances, it combines efficiency, precise handling, and technical solutions for autonomy, control, and cargo management.

Developed to tackle challenging routes, rough terrain, and variable environmental conditions, the Factor Sarana approaches gravel racing with an endurance focus, featuring a design aimed at maintaining consistent performance even after many hours in the saddle. The Cyan Blue livery completes the distinctive character of this bike, designed for those who want to push the limits of traditional gravel.

Designed for Ultra-Distance Competitions

The Factor Sarana was created to meet the specific demands of ultra-endurance races, where speed, reliability, and the ability to cover long distances are essential.

To develop the project, the Factor engineering team collaborated with Rob Britton, a Canadian ultracyclist and winner of the 2025 Unbound XL. His experience in long-distance competitions helped translate riders' needs into concrete design solutions.

Testing in British Columbia on extensive routes and rough terrain allowed the bike to be refined in variable conditions, including heat, rain, elevation changes, and long riding sessions. The result is a gravel racing platform designed to deliver efficiency, responsiveness, and control even in the most demanding situations.

Integrated Storage Compartment and Custom Frame Bags

One of the distinctive features of the Factor Sarana Disc 2026 is the large storage compartment integrated into the down tube. The custom internal bag allows riders to carry tools, accessories, and clothing while keeping their gear organized and protected during long rides.

This solution is particularly useful in self-supported competitions, where riders must manage their own equipment without sacrificing the bike's efficiency.

The Sarana is also compatible with custom frame bags developed in collaboration with Post Carry. These increase cargo capacity and help organize essentials for multi-day adventures, with an integration designed to enhance the frame's aerodynamic efficiency.

Gravel Wheels and Long-Distance Tires

The described configuration includes Zipp 303 XPLR S tubeless-ready wheels paired with 45 mm Goodyear Inter XPLR Gravel tires. This combination is designed for gravel riding and tackling surfaces other than asphalt, offering a balance of rolling efficiency, comfort, and control.

The tubeless-ready setup allows riders to consider a tubeless configuration compatible with the components used, based on their preferences and route conditions.

Dropper Post and Suspension Fork Compatibility

The Factor Sarana offers several customization options to suit more technical gravel routes.

The frame is designed for a 30.9 mm seatpost with an external collar, allowing the installation of a compatible dropper post. This solution lets riders choose a lightweight component with greater travel and less insertion into the frame than other configurations, improving control on technical sections and demanding descents.

A suspension fork with 30 mm of travel can also be installed, adapting the bike to rougher terrain and improving comfort and control over long distances, while remaining within the manufacturer's compatibility specifications.

Black Inc HB05 Integrated Carbon Cockpit

The bike is equipped with the Black Inc HB05 integrated carbon cockpit, developed for aggressive gravel riding. The design, with a reduced drop and pronounced flare, provides a secure grip and precise steering control on rough terrain.

The integrated handlebar and stem create a clean, performance-oriented setup that is particularly appealing for riders tackling endurance competitions and routes that require constant control of the bike.

13-Speed SRAM Force AXS XPLR Electronic Drivetrain

The Factor Sarana Disc Cyan Blue 2026 is equipped with the 13-speed SRAM Force AXS XPLR electronic drivetrain, designed for competitive gravel riding.

The SRAM Force 1 AXS crankset, with 170 mm crank arms and a 42-tooth Wide chainring, is paired with the SRAM XG-1371 XPLR cassette, featuring 10- to 46-tooth gears. This combination offers a wide range of gears for tackling climbs, flat sections, and fast passages, allowing riders to adapt their pedaling to the route's characteristics.

The groupset includes SRAM Force AXS shifters for Flat Mount disc brakes, a SRAM Force AXS XPLR rear derailleur compatible with a maximum 46-tooth cog, and a SRAM Force chain compatible with 12- and 13-speed drivetrains. The system is completed by the SRAM eTap battery and a dedicated USB-C charger.

SRAM Disc Brake System

The braking system uses disc brakes with 160 mm SRAM Paceline Two Piece rotors, featuring Center Lock mounting and a rounded profile.

This configuration completes the Factor Sarana's setup, providing a solution suited for managing braking during gravel rides and long-distance competitions.

A Complete Guide to Bike Sizes

Foreword: Not all bike sizes are the same

Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.

Bicycle adjustment margins

Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.

How to use size charts

We've created a simple guide to help you find the right bike size:

1. Check out our size charts for each bike type.
2. Learn more with specific tips to help you make the right choice.

Size Charts: Find Your Perfect Bike

Gravel and road bikes

Sizes are based on the length of the top tube (in cm), which determines the reach of the bike.

For gravel, measurements may vary slightly due to different geometries, but remain similar.

Mountain bike

MTBs are measured in inches, based on the seat tube.

Sizes also vary depending on the type of MTB: full-suspension , hardtail or fat bike .

Children's bikes

The size depends on the size of the wheels, often associated with age:

What to do with half measures?

If you are between two sizes:

• Comfort : Choose the larger size.
• Performance : Go for the smaller size.

Final tips for choosing

1. Consult the manufacturer's instructions : Always check the brand's guidelines.
2. Ask an expert : a specialized workshop can help you choose based on your height, ideal reach and goals.
3. Test the bike : If possible, test the model you intend to purchase.
