Disk lock with alarm is great soo good i have 3 on my bikes , and a f u c k off big chain that cost me 300 bucks and the padlock was just over 100 , the chain will take 5 mins to cut through with a cutting blade on a grinder , with a sh!t load of noise when i put my slab down i put a hole in the ground and filled with concrete and re-bar , has a hardened steel ring set in it , put it this way if they can get my bikes from out of my shed unnoticed there welcome to my bike as there all insured , but i'll bet they cant get em out , i have had a buddy of mine try with very lil success
