mcours2006, from my understanding the drive train is rear cogset, chain, and front chainring. The chain is worn he showed me by putting the tool that measures that on the chain. I r

About the shifters being near the end of the life, he said they are sloppy and will start to skip gears and such. At this point that is not happening. Though he did clean the cables because he said that was part of the problem and it is hard to shift. I thought it was just my hands getting weaker, he said no it is due to the shifters being old. New shifters will be crisp. I am not even sure I understand that. You might bcle able to purchase second hand shifters and replace the originals. I am not that mechanically inclined.

he did not seem to say anything about being able to clean and repack the wheelbearing in the hub, just that it would need a new wheel. I am not sure if this is the original wheel on the bike but I would think most likely it is. I do try and keep the bike tuned and working in good condition because i ride almost daily.

I am going to look into this further as I need to understand before I can make an informed decision.

Thank-you for your input.
