Well, maybe NO lock is tough enough to defeat New York crooks for long. But the test results in this month's "Cycling Plus" indicate some chains can put up a good fight.

- The Onguard Beast 5016. Lasted 30 minutes. It ought to. It weighs 14 pounds. 6400 grams.

- The Abus Granit 110 Chain with the Abus Granite padlock. Lasted 16 minutes against power tools. 2741 grams. The padlock itself appeared to be "uncuttable".

- The Kryptonite New Yoirk Chain with EV Disk lock. Lasted 15 minutes against power tools. 2790 grams. The chain was plenty tough. The padlock was the weakest part of the design.

- Onguard Mastiff Chain 5021 w/shrouded shackle padlock. 12 minutes. (A shorter version of this chain is sold in the USA as the OnGuard Mastiff 5017...the 5017 weighs 9.5 pounds - 4400 grams).

- The Kryptonite Fahgettaboudit. Lasted only 8 minutes against power tools (due to the "cuttable" padlock). 8.4 pounds. 3800 grams. The chain itself was much tougher than the padlock.


The "best buy" is the OnGuard chain. A Mastiff model with the 12mm chain and the padlock with the covered shackle lasted 12 minutes...yet sells for about half the price of the Fahgettaboudit that lasted just eight minutes.

"Cycling Plus" tested the chain locks as part of an article on protecting bikes at home. A chain that is far too heavy for commuting to work works well at home for locking bikes to a floor anchor or wall anchor.
