KMC B1 Chain

The toughest chain in KMC's portfolio thanks to it's more traditional bushed construction sporting unbeatable strength and longevity. Bushed construction forgoes the usual separate bushing (roller) and formed inner plate shoulders, instead opting to have it formed from the same piece of material as the inner plates for a stronger, stiffer overall construction.
