Yes 531 was superceded a long time ago but for a relatively light responsive and importantly durable tubeset it still takes some beating .I know there are now much lighter tubesets but I like the durability and feel of 531 and I can now afford it and Columbus SLX and Ishiwata 017 which I couldn't do 20 years ago I own one aluminium frame and hope to replace that with 853 as soon as I can afford it.I wouldn't give carbon room in the shed as I feel it's to fragile for my 15 stone and I like my frames to last
