borobike, I don't think you'll be disappointed. I've had mine 2 years, about 11000 miles and no serious issues.
I had to take the DR's off first thing and position by eyeball and instinct to get them right but it sounds like you've already been through that. Since then the front shifter is stiff and falling apart, cables need replacing and I wore out the freewheel. That's about it for repairs.
If and when you change out the crankset please write it up. It's been on my agenda since that 28X38X48 seems limiting - I can't spin the pedals any faster than 38 mph downhill. The main reason I haven't yet is that I'm limited at about the same point, the 48-12 is all I can push anyway at a decent cadence. But I want to change it.
