My old trek nees some updating, I guess after 15 years you have to replace parts.
Currently have grip shift and like it on that bike. If some has some that are newer I would be interested in buying.
I suppose I might be able to put an eight speed cassette on the wheel and upgrade to eight speed shifters also. In case anyone has stuff cheap for me to go that route.
Would consider trigger shifters at the right price also.

I am going to splurge and buy brand new brake pads though! Current ones seem weak, things just don't last anymore.
