I've decided to dismantle my bike and throw it away!
I've a mtb which is about 8 years old, and have been commuting on it for the past year. It needs a new bottom bracket, new rear wheel, new rear tyre and new headset bearings. I saw the same one on Gumtree at two years old for £85 and came to the conclusion the bits needed would cost pretty close to that. I'm also getting short of storage. So I've begun to dismantle it, with the intention of selling/keeping anything useful, throwing the frame away, and getting some practice at stripping things down. I've removed the trigger shift gears, the lights, the handlebars, the stem and then it grew too dark to see what I was doing, so I'll continue tomorrow.
