Buying Guide

Chain material and thickness

Choose chains made from hardened steel or thick square-link alloy — greater thickness and hardened treatments increase cut resistance

Lock mechanism type

Decide between keyed cylinders and combination dials: keyed locks often offer stronger cylinders while 4-digit combos remove the need for keys

Weight versus portability

Heavier chains provide more security but reduce portability; consider length and whether you can comfortably carry a 2–3 ft chain on commutes

Length and securing options

Longer chains let you loop through frame and front wheel and fix to varied racks — a 2–3 ft length balances versatility and carryability

Corrosion resistance and outdoor use

Look for weather-resistant coatings or finishes to protect steel links and lock bodies from rust if you park outdoors frequently
