I don't pretend to know much about mechanics so I need some input from some of you experts. I've got an old 10 speed, circa late 80's early 90's, low end Nishiki. It's got no-name brake components with the old fashioned safety levers, steel rims and gut ripper index/friction shifters on the stem. It's a Suntour accushift gruppo. The frame is a ladies frame of high tensile steel. Because of the placement of the shifters, the shifting is pretty sloppy.
What I'd like to do with this bike in the immediate is:
(a) change out the shifters to???
(b) switch to aluminum wheels for better braking in the wet
(c) get rid of the brake safety levers and change to ???
later I'd like to go to a triple chainring.
Can these things be done to this bike? The frame doesn't sound worth much but I'm looking at buying a new bike which will be a huge sacrifice if I'm able to do it at all. The thing with this frame is that it fits my small frame like a glove. I'm not looking for a pro or high comp level bike. Something that performs around the same level as say the Trek 1200. What do you all think?
