While buying a pannier, try to get one with fewer zips as the dirt and repeated opening and closing can make the zippers prone to failure. Also, these come in different shapes, materials and sizes. Therefore, don’t carry a heavy bag and travel as light as you can while going for bicycle touring.
Medium grade panniers usually have a bungee attachment, but this bungee is usually unmovable and can quickly wear out or break in a short period of time. However, there is always a locking mechanism on the hooks in every good quality pannier. It helps to ensure that they will not bounce off the bicycle racks while riding in rough terrain or over a large bump on the road. To pass through the uneven tracks effortlessly during European bicycle tours carrying a quality pannier is highly recommended.
Most of the touring bicycles are built to carry four panniers, two in the front and two in the rear. However, it depends on the items required to be carried along. It is recommended to carry minimal baggage so as to have a smooth expedition. Prominently, there are two types of panniers, roll-top and bucket style panniers. Roll top panniers are mostly preferred because they are 100% waterproof, on the other hand, bucket style panniers are not completely waterproof, which makes them less feasible to carry.
