The Ortlieb Sport-Roller Core makes every bike tour easier. It fits both on the lowrider and on the rear rack and can also be used for smaller bikes, such as those commonly found on children's bikes. Thanks to the Quick-Lock 2.1 system, the bag can be securely attached to luggage carrier tubes up to 16 millimetres in diameter. PVC-coated polyester fabric guarantees durability and resistance. Reflectors improve visibility and safety. The Ortlieb Sport-Roller Core is dustproof and protects against splashing water - and this is confirmed by the IP 64 protection class.
