I’ve got one of them… I kept meaning to replace it, but there is nothing actually wrong with it – it climbs and descends really well and with a change of components you can build it to do whatever you like (mine has had all sorts over the years – forks from 140-160, triple, double&bash, dual ply high rollers, conti vert pros)
The only issue I had was snapping the swingarm – but that was on its 3rd trip to the alps, and they replaced it under warranty.
I’m currently rebuilding it to be a light weight xc trail bike (to fill the gap between a rocky mountain blizzard and a transition covert).
Long live the (old) 575s, they rock!
