So， Abus Granit Detecto X-Plus 8077 alarm disc locks won't be popular with Johnny Robber. These electronic units clamp onto your brake disc with a 13mm steel bolt. Both the bolt and lock body are engineered from special hardened steel， in addition to elements of the locking mechanism. This Abus 3-D detection system identifies every criminal movement and blasts a 100 decibel alarm for 15 seconds， and then activates again automatically， if needed. Bike bandits will have fled by that point! The X-Plus cylinder offers maximum protection against attempted lock-picking or other manipulation. Abus Granit Detecto X-Plus 8077 alarm disc locks alert you via sound and LED displays about the battery， alarm， and activation status. Two keys (one lighted) and two AAA batteries are included. Choose the color you like--and stay secure!
