1x12 drive concept: Full gear range for maximum riding enjoyment

The latest generation Shimano GRX shifting group takes you wherever you want to go. The 1x12 drivetrain without front derailleur means less shifting and more exploring. The new 12-speed cassette with 10-45 teeth is compactly staggered with a huge range of gears. One of the most popular gravel groups for good reason.

Stable gravel wheels and tyres with good grip

We fit our robust ROSE G30 LIGHT gravel wheels to the BACKROAD GRX RX820: With weight-optimised aluminium rims, high-quality Newmen hubs and sturdy Sapim spokes. The wide inner rim width of 25 mm increases the tyre volume and gives the already snappy WTB Raddler tyre even more stability when cornering.

Wide gravel handlebar: Made for off-roading

You can rely on the Ritchey WCS Venturemax even on root passages or fast gravel tracks. For full control, the handlebar ends are extra wide and the drop is less pronounced than on road bike handlebars. The flat bar top area and the characteristic "Bio-Bend" bend in the drop also provide more long-distance comfort.

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
