| reason | Wilier publishes no defensible conventional equivalence for its letter sizes. No authoritative source could be obtained: wilier.com and its technical PDFs answer 403 to us, so nothing manufacturer-published could be read. Retailers list letters only. Refused for absence of evidence rather than because of contrary evidence — if the source becomes reachable this is worth revisiting. |

"Experience the thrill of gravel riding with the latest Wilier Jaroon 28\", a bike that's as robust as it is agile, designed for both men and women who seek adventure beyond the asphalt. At the heart of this gravel grinder is a lightweight aluminum frame, perfectly complemented by a carbon fork that offers precise steering and absorbs the bumps along your path. The bike's geometry and the flat mount system for the 12 x 142 mm rear axle ensure a comfortable yet responsive ride on any terrain. Equipped with the Shimano GRX RX600-1 crankset, featuring a 40-tooth chainring, and a Shimano CS-M7100 cassette that spans a wide range of 10 to 45 teeth across 12 speeds, this bike is ready to conquer steep hills and race down descents with ease. The absence of a front derailleur highlights its streamlined 1x drivetrain system, simplifying shifting and reducing maintenance without sacrificing performance. Hydraulic disc brakes from Shimano GRX RX610 deliver reliable stopping power in all conditions, ensuring safety and control whether you're navigating muddy trails or dry gravel paths. The Shimano GRX ST-RX610 shift/brake levers offer intuitive control over your ride, making gear changes smooth and braking precise. Rolling on 700 x 40C tires, the Jaroon provides a perfect balance between comfort and traction, making it ideal for long days on mixed surfaces. The frame's compatibility with a 27.2 mm diameter seatpost offers additional options for customization and comfort adjustments. Note that pedals are not included, allowing you to choose the perfect pair to match your riding style and preferences. Whether you're exploring new gravel routes or embarking on epic off-road adventures, the Wilier Jaroon is your gateway to unlimited exploration."
