A while back I purchased some chains from our mates at AliExpress and was warned about them by someone (potentially
@ozzybmx but I cbf'd looking) . The warning was about how they stretch, would only last a week, rust and were of questionable quality.
Well, he was totally wrong. Couldn't have been more wrong.
It didn't even last the test ride, junior (who is hard on the gear I must admit) broke it in the driveway. Made of steel with the same Rockwell hardness as cheese, total rubbish.
For reference, this was a Shimano (Shitmano?) knock off. KMC's are still ok at this point.
