I've got a couple of sections of chain tubing that was excess when I replaced Cycleman's (when he kindly loaned me his Anthrotech).
I don't have a 'bent, so it is entirely surplus to requirement, so can be yours for the cost of PMing me your address.
If you live near me (South London), or work near Southwark, we might be able to arrange a handover which doesn't involve the Royal Mail.
