JeremywellJeremywell 10-PCS #50H Heavy Duty Roller Chain Offset Link (1/2 Link/Half Link)

These fit and function just fine, like any other link. Didn't run them long enough to know about durability yet, so I'm not going to give 5 stars. General impressions of quality are very good, though. These were as low of a price as I could find for chain links of any known name brand.
