## Before you buy

- The listed 32 x 12 x 17 centimetre dimensions are not identified as the chain’s usable length or lock clearance. Check fit for your intended anchor and parking point.
- Listing details conflict: the title and contents list describe a 14mm U-lock, while manufacturer copy calls it a 100D lock with a 16mm shackle. Rating descriptions also differ, with one passage claiming Diamond for cycles and Gold for motorcycles and another describing the lock as Diamond for cycles. Confirm the selected kit’s exact lock and applicable ratings before relying on them for insurance or a motorbike.
