ALUTO Factor: the new long-distance gravel race bike
Race-Bred. Gravel Ready. That's how Factor defines the new ALUTO , its gravel bike designed to be fast in races, efficient on long rides, and capable of tackling any terrain. A bike that doesn't replace the OSTRO Gravel, but rather complements it with a more versatile and adventure-oriented character.
Fast, yet comfortable geometry
The ALUTO combines short chainstays and a straighter head tube for agility, with a slightly higher stack height for added comfort on long rides. The lowered bottom bracket and stiff rear triangle ensure stability even when loaded with wide tires or bikepacking bags. It's a bike that's equally suited to gravel races and 300km adventure rides.
More space, more possibilities
The frame offers clearance for tires up to 47mm in the rear and 52mm in the front . That means you can run fast 38–40mm tires for competitive gravel riding, or 45–47mm tires for exploring rough, technical trails without losing control. A bike that adapts to you, not the other way around.
Practical and intelligent integration
- Internal storage in the downtube: carry tools or spare parts without resorting to external bags.
- 1x and 2x compatibility : choose simplicity or full range according to your gravel riding style.
- 27.2 mm telescopic seatpost ready to mount if you want more safety on technical descents.
- Universal UDH : rear mounting prepared for any future transmission development.
- Electronic transmissions only : aesthetic cleanliness and maximum precision in shifting.
Built to withstand
The frame is made from high-modulus Toray® fiber , the same material Factor uses in its fastest road bikes. The result is a bike that combines lightness, stiffness, and shock absorption, designed to perform equally well on La Traka and Unbound Gravel .
Cockpit and wheels Black Inc
The ALUTO can be fitted with Black Inc. integrated or semi-integrated handlebars, optimized for the gravel riding position (more flare, better control). Furthermore, the frame is tubeless-ready for wide rims, essential for getting the most out of modern gravel tires.
