2x Gravel Bikes (Double Chainring)
Optimized cadence control, close gear spacing, and high-speed efficiency for all-road & mixed surfaces
2x (two-by) drivetrains feature two front chainrings (typically 46/30T or 48/32T sub-compact gravel ratios) paired with a tight-ratio 11-34T or 11-36T rear cassette.
If your gravel riding involves long stretches of tarmac, group pacelines, fast rolling countryside lanes, or bikepacking touring where maintaining an exact pedalling cadence is vital, a 2x setup is unbeatable.

Why Choose a 2x Gravel Drivetrain?
Seamless cadence transitions and unmatched versatility for riders who split time between road and gravel.
Cadence Efficiency on Mixed Terrain
With smaller percentage steps between adjacent cogs (often just 1 to 2 teeth in the cruising zone), you will always find the exact right gear for your preferred cadence, saving valuable energy over long distance sportives and multi-hour rides.
- ✓Sub-compact 46/30T front chainrings provide sub-1:1 low gears for steep climbs.
- ✓46T or 48T big ring provides ample top-end speed for fast road descents.
- ✓Ideal for "one-bike-to-do-it-all" riders using interchangeable wheelsets for road and gravel.
Frequently Asked Questions
Is 2x gearing good for steep gravel hills?
Yes! A 30T small chainring paired with a 34T or 36T rear cassette delivers a lower climbing gear than many standard road bikes, making steep off-road climbs manageable.
