Review on Shimano HG71 6-8 Speed Chain by Aneta Jastrzbska ᠌

Revainrating 3 out of 5

The product is average, Im not sure its worth the money.

The chain has traveled 6000 km. He did a measurement on the chain tension. For 100 links, it stretched by 6.5 mm (0.5% of the length or 50% wear), but the problem is far from the chain stretch, but the rollers themselves. They are very much demolished both externally and internally. If you take measurements inside the chain between the rollers, then the wear exceeds the norm by approximately 25-30 times.
