Reading the angst on the 'should I sell it' thread, I started to wonder if there's a list of bikes - as a committed/deluded/passionate/obsessed mountain biker you 'should' have at least ridden and probably owned. The petrol head equivalent would be the Alfa Romeo I guess.
The Santa Cruz Chameleon comes to mind. You cannot ride one without grinning. Or, as you get older, grimacing. Not sure what the classic steel or Ti frame is (I'm biased and would say Trailstar and Hummer) and that's before we get onto FS (LTS maybe?)
What says the hive mind?
