guys just picked up a secondhand 3 speed brompton for my son.I have checked the chain with a parks chain measurer and the chain has quite a bit of stretch.was going to replace chain and sprocket.Looking for advice to where I can pick up the sram quick link chain and sprocket.I have not removed the sprocket yet but believe the standard sprocket is a 15t and the chain to go for is the sram pc1, any help appreciated
