Are there any things i should be looking out for or any issues i need to be aware of?
You should keep an eye out for little (or big!) cracks in the frame around the aluminium parts. They could spell big trouble.
STS´s are apparently prone to breaking in those areas, although I haven't had any problems in the 11 years I've had mine.
The bike has brake jack and does pedal-bob a little on granny gear, but those aren't such a big a deal, the bike is sweet overall. I've always thought it climbs especially well. Just set the rear shock to your liking and off you go! Have fun!
I've a question of my own, too: I've put off changing derailer wires for quite some time, but I'll have to do it soon. Someone said earlier in the thread they'd lost the wire into the frame and took some time to get it out again...how does one change the wires the right
