This is the newest MTB I own
. It was my main race/train bike up until the point that I broke my collar bone, and subsequently switched to being a roadie. Other than being used to roll around the neighborhood with my kids when they were young, it's been ignored for over 20 years. I had thoughts of updating the drivetrain to something more modern (was 7-speed), but recently decided to go a different direction with it - single speed. I'm not willing to invest more than a few hundred dollars to make the changes I want. With full drivetrain, it weighed 24 lbs. I'm expecting to get to about 22 in its final form.
First step - strip off the unnecessary parts (shifter, derailleurs, extra gears...)
Parts needed:
Chainring (this one is missing teeth and pretty trashed)
Chainring bolts
Chain
Chain tensioner
Stem (shorter)
Handlebar (wider)
Grips
Tires (probably 2.1, but might go a bit wider, depending on what I can find available)
Tubes (or tubeless conversion)
