Agile. Centered. Versatile.
The ALUTO is driven to perform. In races. On long adventures. Across all types of terrains. With a design that’s laser focused on feeling bright, elastic and responsive, the ALUTO is built for riders who demand a balanced ride that combines Factor-level handling with the perfect synergy of speed and capability. With a geometry tuned to perform across changing terrain and on longer rides, the ALUTO has been engineered to feel agile by using short chainstays, a steep head tube, short wheelbase, and lowered bottom bracket to reduce centre of gravity and accommodate the increased height of gravel tyres. The tube shaping and carbon lay-up has been engineered to deliver stiffness where it’s needed and to be forgiving where it’s wanted. It is a bike that feels bright, light, and alive. A pocketknife. With a razor’s edge.

Balanced Race Geometry
Going wider for tyre clearance is not just a matter of increasing the width of the fork and seatstays. Increased tyre volume has a direct impact on the handling as well as the effective geometry. The ALUTO’s geometry has been optimised around 45 mm tyres with a performance maximum of 47 mm as measured tyre clearance in the rear. This balanced decision ensures the handling remains sharp and snappy. Compared to the OSTRO Gravel, the ALUTO has a slightly steeper head tube angle and equally short chainstays to maintain a shorter wheelbase and enhance agility. We’ve lowered the bottom bracket to shift the centre of gravity downward, stabilising the ride and balancing the shorter wheelbase while increasing control across variable terrain. With a slightly higher stack than the OSTRO Gravel, the ALUTO allows for a more adaptable fit for a wider range of riders without compromising a race-ready position.

Balanced Front-End Feel
Keeping the handling sharp and responsive remained a top priority for Factor engineers when designing the ALUTO. Even when running the allowed maximum tyre width, the bike still needed to feel nimble. The minimal-design fork with reduced volume delivers forgiveness without softness, while increasing responsiveness. It’s a construction that works harmoniously with the wide volume tyres to enhance the comfort levels and grip, without dampening the agility. The handling of the ALUTO is sharp but tuned for fatigue resistance. The carbon lay-up for the front end combines with the tube shapes to provide a brighter, lighter ride feel over long hours.

Functional Integration
Long distance racing, training, and exploring all require not only high performance design cues, but utilitarian integration. Down tube storage provides a secure, aero solution that allows the rider to stash tools and other essentials without the need of a saddle bag or bar bag, both of which cause dramatic drag. Whether the ride will last 30 or 300 kilometres, having a safe place to store tyre repair kit and a multitool ensures that you’ll be able to fix all the most common mechanicals. The ALUTO frame accepts only electronic drivetrains with hydraulic brakes, removing the need to include additional holes and ports for mechanical drivetrains. The full internal cable routing has been designed to be mechanic-friendly while offering clean aesthetics and optimal cable protection.

Built for Modern Gravel Racing
The remit for the ALUTO was to design a bike that could be fast from rough tarmac to technical mountain trails. The 1x and 2x compatibility was an important feature decision since it allows the rider to set up the bike for their most likely case-use scenario. Someone more focused on road and light gravel courses will likely gravitate to the 2x option while those seeking to make it more off-road adventure-worthy will likely appreciate the ability to build it up with a 1x without clutter. Multiple mountain points for bottle cages and a bento box support everything from race-day minimalism to light adventure setups. A round seatpost (27.2) with external clamp offers both ease of adjustment and dropper post compatibility. And the now nearly ubiquitous UDH-compatible rear dropout ensures drivetrain flexibility and future-proofs the frame for future drivetrain upgrades.

Ready to go long
The ALUTO doesn’t sit below the OSTRO Gravel, it stands beside it. It’s as sharp, fast, and technically focused as anything in the category. But it’s also centred, balanced, and built to go long. From dirty short courses to 300km adventures, this is the race-capable gravel bike for riders who do it all and demand more.

In-frame storage
With the ability to fit tubes, CO2 cartridges, a patch kit, the ALUTO in-frame storage eliminates the need for a saddle bag or bar bag, which will save significant watts of drag. On-the-bike self-sufficiency no longer needs to come at the expense of aerodynamics or sleek appearance.

Wide tyre clearance
Offering a maximum of 47 mm rear tyre and 52 mm front tyre clearance, the ALUTO can tackle the toughest gravel races with confidence. From Traka to Unbound and beyond, the ALUTO mixes rough terrain capability and comfort with road-like responsiveness.

Race geometry
Thanks to well-considered geometry choices, the ALUTO rides with the tight handling and centred weight distribution of a purebred race bike, no matter the terrain. Designed for modern gravel athletes who demand responsiveness and endurance in the same bike, the ALUTO is built with clarity, not compromise. Every detail serves the ride.

UDH compatible
Making the ALUTO UDH compatible opens the door to 1x as well as 2x set-ups depending on intended use scenarios

Fully round steer tube
The head tube design uses 1.5" upper bearings, which allow for internal routing with the round steer tube. Aerodynamics enhanced by minimal but purposeful hourglass shape.

T47A bottom bracket
Using the same bottom bracket standard as the OSTRO Gravel, the ALUTO can accept a wide variety of cranksets to accommodate multiple use scenarios.

Dropper post compatibility
Thanks to the standard round seatpost design (27.2) and lightly sculpted seat tube shape, a dropper post can be employed for those seeking gnarly descents.
