Chain lock vs U lock: Execs and cons
It doesn’t matter what kind of lock you go together with there’s going to be a variety of safety choices. Chain locks encompass hardened metal hyperlinks that interlock to make up the size desired. These hyperlinks are one a part of the safety and the opposite half is the system used to lock the hyperlinks collectively on the finish. The opposite commonest kind of lock consists of a strong metal bar that curves right into a U form. The final a part of the system is a retaining bar that when locked completes a D form. These locks go by the title U locks within the US and D-locks within the UK.
Going again to a pure safety focus, there is not any distinction between the 2 types. Extra metal shall be safer, and 12mm metal shall be safer than 8mm metal, however that alone does not dictate a selected fashion of lock. When you’ve got a U lock with 12mm shackles and a sequence lock with 12mm hyperlinks, then the safety would be the similar. One caveat is that on the U lock facet you will wish to guarantee that the retainer bar locks at each side in order that it takes two cuts to open it.
The place the place lock types diverge is of their usability and portability. Extra metal means extra weight, which is why so much folks go for one of many finest light-weight bike locks as a substitute.

That would imply a thief is ready to stand on a bolt cutter to get extra leverage. Alongside the identical strains, the extra space between the lock and the bike, the extra weak it’s. It leaves the lock open to a leverage assault the place one thing like a bar supplies leverage to drive a lock open. It additionally makes it simpler to make use of a transportable angle grinder with out damaging the bike.
It is for these causes that the very best safety U locks are smaller. The producers are attempting to make it more durable to depart house for thieves to realize a bonus. The problem is that U locks are all the time the identical dimension. Chains have a bonus right here. Once you’ve received a smaller anchor level, you possibly can wrap the lock in order that it is nearer to the bike. Once you’ve received an even bigger anchor, you should utilize an alternate path to maximise the size out there for wrapping the anchor.
Your alternative of chain vs U lock isn’t about which is healthier.

U locks additionally use much less materials and which means they are typically inexpensive. In the event you want extra flexibility although, both for bigger anchors, larger tube sizes, or possibly a number of bikes, then a sequence lock will present that flexibility. The draw back is that the chain shall be heavier and sometimes costlier.
