Gravel
Titanium 3AL2.5V
Overview Features Details
Custom

Gravel is more than a road surface. It is a way of riding beyond the limits of any one terrain.

From paved roads and forest trails to gravel tracks and rugged paths, it strikes an excellent balance between stable handling, comfort, and speed. Wide tires and the resilience of a metal frame help absorb road vibrations, keeping your riding rhythm smooth and confident as the terrain changes. These qualities also give gravel bikes exceptional stability and capability on demanding surfaces such as the iconic cobblestones of Paris–Roubaix.

“Just as pebbles are shaped by time and waves, riders grow with every journey into the unknown.”

More Confident Handling

A head tube with a 44 mm internal diameter paired with a 1-1/2-inch tapered fork increases front-end stiffness and steering precision, delivering stable, confident handling during fast cruising, climbs, and cornering. The generous head tube space also supports fully internal cable routing, concealing cables from the handlebar and stem for a clean appearance, aerodynamic benefits, and a refined finish.
Easy Maintenance

The T47 bottom bracket standard combines a large-diameter shell with a threaded interface, increasing stiffness around the bottom bracket and transferring pedaling power more efficiently into forward momentum. Excellent compatibility and easy maintenance make T47 a dependable choice for both high-performance riding and long-term use.
Flexibility for Future Upgrades

The frame fully supports both electronic and mechanical shifting, with internal routing ports for electronic systems and a mount for a mechanical front derailleur. Riders can configure the drivetrain to suit their riding needs and personal preferences, with greater flexibility for their build and room for future upgrades.
Ready for the Journey

Rack mounts on the fork and seatstays accommodate a wide range of racks and carrying systems. From daily commuting and long-distance touring to bikepacking adventures, you can tailor the setup to each journey, expanding the frame’s versatility.
