New 12-speed groupset with gravel-oriented drivetrain

The new GRX RX820 gravel groupset by SHIMANO is equipped with first-class technologies and is SHIMANO's high-end mechanical groupset for versatile and demanding gravel action. The drive concept with two chainrings at the front ensures small gear steps so that you always remain in the optimum cadence range. Ideal for racing use and long-distance adventures on gravel and other surfaces.

Wheels/tyres

This bike is equipped with robust ROSE G THIRTY LIGHT gravel wheels, as well as with high-quality Newman hubs and stable Sapim spokes. With their wider inner rim width of 25 mm, they increase the contact area of the gravel tyre and thus provide more grip on rough terrain.

Road bike handlebars for long stretches

The drop bar ensures a back-friendly posture and increases comfort on the long haul. In addition, the SHIMANO GRX gravel shifting groupset comes with a shift and brake lever combination that has been adapted for gravel use. It also ensures a comfortable and a secure grip off-road thanks to the raised, horned shape of the grips and ergonomically shaped levers with an anti-slip coating.

Category 2

This category applies to bicycles and e-bikes* that meet the conditions of category 1 and are ridden on normal roads as well as in category 2 on unpaved roads and gravel paths with moderate inclines and descents. The tyres are in constant contact with the ground at average speed and they are only occasionally ridden over steps and drops of less than 15 cm. These conditions can lead to contact with uneven terrain and the tyre repeatedly losing contact with the ground. The intended use is, for example, recreational riding. You don’t require any special riding skills.

Average speed 15 to 25 km/h

Height of steps and drops: < 15 cm

*E-Bikes = 250W 25km/h
