Back-Roller Design Sierra 20 L Green-Black

The Back-Roller Design 20L Green - Black is a bicycle bag from Ortlieb.

Designed with these prints to add a splash of colour to your rainy commute to work, this highly waterproof and robust pannier detaches and attaches quickly from the luggage rack so you can take it anywhere. It is fitted with the Quick-Lock 2.1 system which fits all pipe diameters of up to 16 mm, and reducers are provided. For 18mm, 20mm etc. tubes, however, you will need to buy the hooks separately.

With its 20-litre storage capacity, high-quality materials and adjustable roll-up closure, you can keep all your gear protected from water and dust, whatever the weather and whatever the terrain.

In terms of practical features, it has an internal pocket for separating your sensitive equipment, for example, and a carrying strap so you can take it with you wherever you go.
