I've just got an Almax chain 2m long and 19mm links and the sleeve has seen better days, been told I can get a new sleeve for about £12. I've also got a short length of fire hose which I'm thinking of using.......its not as flexible so if you're not carrying it on the bike then that maybe an option for you, ask your local station if they have a burst length that's no good anymore......you'll need the old 70mm (64 now) as opposed to the 45mm hose
