A buddy of mine is selling his 2004 Giant NRS1, size 18.5 (medium). It has literally been in his basement for three or more years, unridden. In the add it shows tires and rear derailleur being replaced. The rear derailleur is now a Shimano XTR and the tires are Maxxis Advantage (front) and Kenda Small Block (rear). The bike is in great shape and is practically brand new, it was probably ridden less than five times on pavement only.
