barracuda thriller mountain bike

I brought a barracuda thriller from ebay 5 years ago but i have changed most parts of the bike all that is standard are the handle bars seat post and crank (which is worn out) and bottom braket. I put the following parts on it suntour xcm forks, front and rear shimano disk brakes, new back wheel with disk hub, rapid fire shifters, air sprung rear shock, oh it still has orininal tyres with slime tape in them. I emmigrated to Texas U.S.A and shipped the bike over when i moved i use the bike for off road and seriois trail riding, the West Texas sand has played havok with the gears even with dry moly chain lube and the bike get used alot it needs new crank bottom bracket and rear cassett after 4 years of hard riding the frame is excellent and has put up with alot of rough riding i can not fault the frame its everything i wanted. When i brough the bike i wanted a sturdy frame as i have broken 3 mountain bike frames and built the bike i wanted out of the standard barracuda thriller.
