It is in good used condition and has 21 gears with a Shimano STC rear derailleur.
It is fitted with WTB VelociRaptor 2.1 Tyres which have plenty of tread remaining as can be seen from the photographs.
Everything works and the bike has been well cared for. It would benefit from a service but brakes and hubs are in good adjustment.
This is the famous GT Frame with the additional triangle below the seatpost and makes for an extremely strong hardtail bike. I have used it for touring and there was no sway or whipping effect on the frame at all.
