What to Compare Before Buying
Check the chain’s reach against the item and anchor point you intend to secure. The product is offered with other stated lengths and thicknesses, so confirm the selected configuration rather than relying on the general listing name. Length alone does not establish whether a particular arrangement will fit.
The fabric covering is intended to help keep the chain from scratching a bicycle frame. Position the chain so the covering remains between the chain and the frame where they touch.
Before You Decide
Confirm the selected length and thickness, and make sure the chain can reach around both the item and its anchor point. This lock does not make a bicycle theft-proof; the product description notes that no bike lock is 100% safe.
