Good good
This item did the job. Plenty of links and easy to install provided you have a chain tool that can drive pin out to remove the required number of links. As for delivery. On this rare occasion, Amazon managed to deliver on time.

It's a chain, for a single speed bike.
It's a chain. For a single speed bike. Nothing more exciting than than really. It does exactly what you want it to do. Doesn't snap, which is quite important. Take the plunge!

Low quality cheap rubbish
The feel and look of this chain just screems poor quality. I don't think I'll be leaving it on long and I won't risk a long ride. Wish I'd spent a little more and bought a Shimano or SRAM chain.

Meine Empfehlung
Kette wurde schnell geliefert und ist mit einem schützenden Öl beschichtet. Das Kettenschloss ist sehr gut in der Handhabung, und somit schnell montiert. Auch wenn die Kette gekürzt werden muss, finden die Kettenglieder ohne Probleme wieder zueinander. Top Produkt
