1x Gravel Bikes (Single Chainring)
Single chainring simplicity, maximum tyre clearance, and chain retention for off-road trails
1x (pronounced "one-by") drivetrains eliminate the front derailleur entirely, pairing a single narrow-wide chainring with a wide-range rear cassette (such as 10-44T, 11-42T, or 10-52T "mullet" setups).
By removing the front mech, 1x bikes reduce mechanical complexity, shed weight, eliminate chain drops over rough washboard tracks, and open up extra frame space for wider tyre clearances and mud shedding.

Why Choose a 1x Gravel Drivetrain?
Simplicity, chain security, and off-road focus make 1x the go-to setup for UK trails.
Key Advantages of 1x Systems
With only one shifter to operate, gear selection is intuitive: push one lever to go easier, one to go harder. Combined with clutch rear derailleurs and narrow-wide tooth profiles, your chain stays locked on over the rockiest terrain.
- ✓No front derailleur means no dropped chains or mud jamming around the seat tube.
- ✓Clutch rear derailleurs eliminate noisy chain slap against the chainstay.
- ✓Allows frame designers to widen chainstays for 45mm–50mm+ tyre clearances.
Frequently Asked Questions
Will I run out of gears on the road with a 1x gravel bike?
With a standard 40T front chainring and a 10T or 11T small rear cog, you can comfortably pedal up to 28–32 mph (45–50 km/h) before spinning out, which is plenty for 95% of gravel and road descents.
