Good morning,
Sometimes it is easy to get too nostalgic, says the bloke with one of the 40th aniversary Raleigh frames, so I am going to be a little bit negative on the selling it front.
I love steel, I ride a new steel frame with 2x8 DT, but I don't love 2x6. For me 8 speed was the cut off point for more sprockets being useful so 6 Speed is a step backwards that I wouldn't pay much to take.
I love steel, but plain carbon steel is functional and for me aluminium trounces it. 531 main tubes only with carbon steel forks and stays is very much a step in the right direction, but only a step. Again I wouldn't pay much to take that step.
But I am frequently wrong and it may fly off
ebay within a couple of days for a fortune.
There is this being sold as unridden, 531 Competition would be tubes, forks and stays,

For a short while I rode an 11-32 8 speed cassette, 11,13,15,18,21,24,28,32 and found that I was forever swapping between 15,18 and 21 as I had become so used to the closer 15,17,19,21.
6 speed brings that gap back or a too small for me large sprocket meaning more chain ring changes.
It's definitely a bike to ride all year round and if it rusts so be it.
Bye
Ian
