After running down the battery on their cordless angle grinder, it’s no wonder that Bicycling Rated our Mastiff as the Best Chain Lock.
“The 3.5-foot-long chain uses 10mm-thick, titanium-reinforced steel links that are hexagonally shaped to make cutting even more difficult. (The Mastiff ran down the battery of our tester’s cordless angle grinder when we attempted to cut one in 2013.)”
