Abus BORDO GRANIT™ XPlus™ 6500K/90 black SH

Only the Flex can crack the Bordo granite. It resists all other attempts to break it open. The holder is also excellent, it can be attached to the bottle cage eyelets with screws, Velcro straps and tube clamps on the frame. Top: the Abus Key-Card (see p. 37).

81 models compete in the Stiftung Warentest bicycle lock test. Almost a third failed. Fortunately, there are also good locks for little money.
