Wilier
JaroonShimano GRX 2x10s WTB
The current Wilier Jaroon marks a clear repositioning of the model as a modern aluminum gravel and adventure bike rather than a niche all-road option. Wilier builds it around a new alloy frame with fully internal cable routing, a rear thru-axle, flat-mount disc brakes, and a monocoque carbon fork, bringing the platform in line with contemporary gravel standards. At the same time, the Jaroon keeps a deliberately practical brief: it is designed to cover commuting, mixed-surface riding, light touring, and bikepacking rather than chasing a pure race-gravel identity.
What sets the Jaroon apart is how explicitly it prioritizes versatility. The frame uses a 27.2 mm seatpost for added compliance, clears tires up to 45 mm, and includes mounts for mudguards plus front and rear racks. Those details make it a credible option for riders who want one bike for everyday transport, rough gravel, and loaded trips. In the market, it sits as a utility-forward gravel bike with cleaner integration and updated standards, aimed at riders who value stability, carrying capacity, and broad compatibility over the sharper handling and tighter packaging of more race-focused gravel models.

Geometry & fit.
5 sizes published.
The Jaroon's geometry points strongly toward stable, confidence-first handling. Across every size, Wilier uses a 70° head tube angle and 440 mm chainstays, paired with a relatively long wheelbase that ranges from 1037 mm in XS to 1104 mm in XL. For a gravel bike, that is a notably calm layout: the slack front end and long rear center should improve composure on descents, loose surfaces, and loaded rides, while also reducing the quick, nervous steering feel associated with more race-oriented gravel bikes.
Fit numbers are moderate rather than aggressively stretched. Reach runs from 384 mm in XS to 417 mm in XL, while stack goes from 548 mm to 626 mm, suggesting a generally upright and accessible position. Effective top tube lengths from 540 mm to 600 mm reinforce that the Jaroon is intended to be easy to live with over long mixed-terrain rides rather than optimized around an especially low or aerodynamic posture. The consistent 74° seat tube angle keeps rider positioning fairly neutral, which should suit a wide range of uses from day rides to commuting and bikepacking.

The lineup.
2 builds, ranging $2,200 – $2,950.
Wilier offers the Jaroon in two builds: a Shimano GRX 2x10s WTB version and a Shimano GRX 1x12s WTB version. Even without detailed component breakdowns or pricing, the split is telling. The 2x10 build is the more traditional all-rounder, likely aimed at riders who want tighter gear steps and broader gearing flexibility for mixed road and gravel use. The 1x12 build targets riders who prefer simpler operation and a drivetrain better suited to rough-surface riding and lower-maintenance adventure use.
Both builds appear to share the same core platform and WTB finishing choices, so the main decision is drivetrain philosophy rather than frame intent. That makes the range straightforward: one option leans toward versatility and cadence range, while the other emphasizes simplicity and off-road practicality.
