Guy at my school had a full Suntour XTR groupset, now that is rare!
All you need is:
-A low end Raleigh mountain bike with suntour bits
-A black marker pen, permenant and waterproof is preferable
-A bit of time on your hands
Add all three of the above and jobs a good'un. Unfortunately not many of us were impressed by the overall quality of his XTR groupset, maybe that's why I don't own a bike with XTR on it to this day!
