2026 aluminum gravel bike
REVOLT 2
A versatile aluminum gravel bike built for pavement, dirt roads and weekend exploration, with a composite fork, adaptable flip-chip geometry and clearance for tires up to 53 mm.
Key performance factors
Confident wherever the road ends
Confident handling
Endurance-oriented geometry, shorter chainstays and a low bottom bracket create stable, predictable control on pavement and rough terrain.
Tuned compliance
Dropped seatstays, the D-Fuse seatpost and the ergonomic Contact XR handlebar help reduce vibration without compromising pedaling response.
Terrain adaptability
The rear flip chip changes wheelbase and tire clearance: short for quicker handling, or long for added stability and tires up to 53 mm.
Technology
Practical performance for mixed surfaces
ALUXX aluminum
A durable 6061-series aluminum frame uses shaped, single-butted tubing to balance strength, weight and value.
Composite fork
An Advanced-grade composite fork and full-composite steerer reduce front-end vibration and support precise steering.
D-Fuse compliance
The shaped alloy seatpost flexes under load to soften impacts while remaining laterally stable during hard efforts.
Flip-chip dropout
Two rear axle positions let riders tune handling and wheelbase while expanding measured tire clearance from 45 to 53 mm.
