The Wilier Jaroon GRX 1×11 is the one-by version of Wilier’s steel gravel bike. A double-butted chromoly frame, a carbon fork and 42 mm tyre clearance meet a simple, quiet Shimano GRX drivetrain. So you get the feel of steel with modern gravel gearing.
Wilier Jaroon GRX 1×11 – one shifter, eleven gears
Shimano GRX 1×11 runs a 40T chainring with an 11-42T cassette. There is no front derailleur to trim, and the clutch rear derailleur keeps the chain quiet over rough ground. Plus the GRX RX400 hydraulic disc brakes give you strong, easy braking in the wet or dry.

Steel, Done Properly
Wilier draws the Jaroon’s tubes in double-butted chromoly, then welds them from the inside so the joints stay clean. Steel flexes a little under load, and that is the point. Because the frame absorbs vibration, you finish a long gravel day with fresher hands and a happier back. The 27.2 mm seatpost adds a touch more comfort again.
Carbon Fork, Modern Standards
A full carbon fork keeps the front end light and precise. It uses a 12 mm thru axle and flat-mount calipers, so it takes any current disc brake. The frame matches it with a rear thru axle. So the Jaroon feels modern where it matters, even though the material is classic.
Ready For Racks, Guards And 42 mm Tyres
Mounts for a rear rack and full mudguards come as standard. So the same bike can commute through winter, then head bush on the weekend. It ships with 40 mm Kenda Happy Medium tyres and has room for 42 mm. Also, the 12° flared bar gives you a wider, calmer stance on loose descents.
