Which? Magazine recently tested padlocks – fifteen of them from eight different manufacturers. The best was a stainless steel disc padlock made by Abus (model no 20C70) which defeated their expert lock pickers. The padlock weighs 260g and with a reasonable-quality hardened-steel chain should be no heavier than most D locks, at least as secure and more versatile for locking up a bicycle. It can be obtained from D Mackay at 85 East Road (01223) 517000 for £28.91.
Surprisingly the worst was also made by Abus (model no 41/30), described as truly awful with abysmal security and durability, and to be avoided at all costs. The full report can be read on pages 46 and 47 of the March edition of Which? magazine. This can be consulted by all in the reference section of the Central Library in Lion Yard.
