Easy to mount on bikes thanks to Vario hook
Wherever you are going, the B3 bag is your faithful companion. This pannier has a built-in Vario hook that makes it easy and straightforward to mount on any bike cargo rack (Ø 6-16m). The Vario hook is highly resilient and bears the bag with ease, even when heavy. Two ergonomic handles make removing the bag just as easy as it is to mount and allows the bag to be carried comfortably.

With roller function for easy transport anywhere, anytime
With its practical roller function, the B3 bag is the perfect choice whether on bike or on foot. The built-in telescoping handle on the back of the bag can be easily extended when needed and is stowed just as quickly in a zippered compartment when not needed. Two highly durable, smooth-running casters maneuver the pannier securely over any surface.

Waterproof, rugged, long-lasting material
Extended bike tours can get dirty, especially when the path goes off road. No problem for the B3 bag: The waterproof, long-lasting material prevents any moisture or dirt from getting inside the bag. This pannier comes in three different colors to suit your taste: black, gray, and denim blue
