When I visit my LBS I usually just get laughed at for owning 'obsolete kit'. They didn't like my Vitus Futural at all and told me that it was dangerous and not to ride it. I took in my DB the other day and showed off my thumbies. I got told that it would be better to fit something more reliable and that they look like the Sturmey Archer 5 speeds that they sell.....
I've taken it all in good humour. I love my bikes and would never part with them. You are right though, they do seem to get more attention than something modern. Be it negative or positive, its all good in my book.
I reckon it depends, I took my RSP to Halfords, and the mechanic thought I should get some Hollowtech Cranks and Hollowtech bottom bracket, he seemed to think Phil Wood and Syncros were Mickey Mouse or crap.
At another LBS the guy admired my bike then said I've the wrong hubs on the wheels (XT on Mavic 517 Sup) and I should replace the Mavics with LX Wheels.
