Norwich FG

Errr I seemed to have opened pandora's box...Well the men in suits are re-developing Norwich and with Browntonian's mass housebuilding ravens gathering; will this quaint medieval city still have any of it's dark heart remaining in the decades to come?

But I didn't quite get that link Turpe? I understand that I will be tightening my sprocket but it says I won't need my lockring? But the lockring is to make the hub fixed isn't it?
