Curse of the mountain bike : Part III

 At least now u r now starting to see why i think of these problems as a curse. They are so many i have had to write 3 posts! I'll try to wind up. First i am proud to say the bike is quite stable now. 1 problem free week. Okay so after the gear stuff was replaced, it never helped. I took it back and they told me that the chain needed replacing. My dad took the bike later and told them to take their filthy gear stuff off my bike and returned mine. After days of crappy riding, thank God the chain broke and was replaced . That at least reduced the frequency of the gear 'jumping' but never fully solved the problem even to today. Later i discovered that the back tyre had been loose for quite sometime. Because i remembered that the bike produced a grinding sound. My dad took it for repair and it was tightened. Just a few rides after the tyre was back to shaking like a loose tooth. He later took it back again and since his tightening never solved the problem, he was asked to replace that metal where the spokes are attached to. That seemed to solve the problem. Unfortunately the spokes were loosely connected and when i was riding' suddenly the tyre curved in like as if it had been hit by a matatu. My dad came to a conclusion that the bike repair guy was a quack and he took it to this place which i haven't know up to now. Well they did a good job. The tyre is as good as new. One week later the front wheel decided to loosen up pretty bad in such a way that you couldn't ride it. Well my dad a week later took it the magical repair man and the bike came back looking new. One week now, no problems save for a few gear problems here and there , but then again riding my bike has never been sweeter!! Thanks for reading.
