Hi I'm Steve, I live in wet Somerset so have been house bound for what seems like months! I've been using the site for years for tips and ideas but finally need to start asking some serious questions. I have several bikes Flandria, Raleigh 753 ST Frame (late 70s Royale I think) Kona AA, Gary Fisher and a Scott and a very interesting 753 frame that fully loaded weighs in at about 8 kg but have no idea what it is? So I'm here to try and find out what it is. Thanks S
