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.

Opis

The BACKROAD GRX RX820 gives you the freedom to try out just about anything. A well-balanced all-rounder for fast gravel roads, tricky root paths or sweaty climbs.

The extremely versatile frame concept of the BACKROAD Carbon meets a mechanical 1x12 gravel drivetrain from Shimano. This gives you a huge range of gears that can be shifted quickly and reliably, even off-road. The necessary grip and comfort are provided by wide gravel tyres from WTB, which roll on light and robust G30 LIGHT aluminium wheels.

The wide gravel handlebar from Ritchey is not only easy to control, but also offers first-class ergonomic comfort. The flexing seat post also provides relief at the rear. Whether sporty, fun or touring – with this bike you decide.


More long distance | Endurance
Flex is fun: The deep cut-out in the seat tube provides a massive increase in comfort, while the balanced frame geometry offers perfect handling on the road, gravel and technical terrain. Only a dry throat can stop you.

More off-road | Action
The frame and fork allow for a tyre width of up to 45 mm with 700c and up to 47 mm with 650b wheels. For rougher road conditions, perfectly adapted protectors at the down tube and chainstays protect the paint.

More experience | Adventure
Thanks to its many attachment points for bottle cages, Anything Cages or bags, the BACKROAD offers ultimate versatility, perfect for a day trip or bikepacking adventures.


*Weight: approx. 8.9 kg. May vary by up to +/- 5% due to manufacturing tolerances. Weight with frame colour evil pepper green, 
size 57 cm, without pedals.

*Slight colour and paint deviations possible on frame and fork set.

BACKROAD GRX RX820 1x12

Kolor: 
*blue haze
Rozmiar:
55cm
Hallo ,
ich habe am 16.4.24 mein Backroad GRX
RX 820 in Bocholt abgeholt. Bin extra aus Frankfurt am Main angereist. Es war wirklich ein toller Service, alle die ich ansprach waren sehr kompetent. Die Übergabe war echt klasse, ich war sehr zufrieden. Der Service und auch das Geschäft in Bocholt kann ich nur empfehlen.
Dort werde ich auch weiter einkaufen. Meine Frau möchte jetzt auch ein Gravel Bike, aber leider gibt es dafür extrem lange Lieferzeiten.

Grüße
Holger

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
