Capable in Any Condition
All-Road Performance
Whether the road is wet pavement or dry dirt, the 4130 All-Road inspires confidence. The thru-axle dropouts (12x100mm front, 12x142mm rear) ensure the frame handles precisely under load, while the disc brakes provide reliable stopping power in all weather conditions. It's a bike designed to keep going when the pavement ends.
Double The Versatility
2-Bikes-in-1
Make it two bikes in one by selecting "both" as your wheelset choice. You can swap between 700c wheels with slick tires for efficient commuting and 650b wheels with knobby tires for off-road adventures. The frame is optimized to handle both sizes, giving you maximum versatility without needing a second bike.
