A happy new year to all,
i wish i could continue on the festive cheer but i have a repeated problem with my derailleur and would love someone with more knowledge to have some input.
When changing gear one day i noticed there was a problem with my derailleur.......the fact was the upper of the two cogs just wasnt there! The cog had completely dropped off the bike whist shifting! In my disappointed state i went to a repair shop (which i have to admit uses second hand parts) to fix it and the problem seemed fine but alas, after about 15 miles, the very same thing happened.
I understand that its is very difficult to diagnose such a problem when not with the bike, but i am wondering if anyone knows of any common problems which may put undue pressure on this part which then causes it to disintegrate!
Is it time for a new bike you think? Or are such things repairable without changing the derailleur, free wheel, chain etc.
Any advice would be appreciated.
