So rolling on from looking for some savings on chains,
I’m fitting a KMC B1 today and noticed it’s a bushed chain where the z1 is bushingless.
I thought bushed was better, it’s what izumi supertoughs and HKKs etc are after all?
Kmc site says bushed are less forgiving of misalignment but if that’s not an issue then it seems like switching to use B1 chains is an easier way to save some money than buying a 50m roll.
Z1 on left, B1 on right.
