I've started putting things back together, refurbing the original components as I go.
Wheels - Striped, cleaned, new bearings, trued and tensioned: The bike still had the original brake blocks on it, albeit worn right through to the metal which left a few nice gouges on the rims. I ended up sanding these out.
Headset - Clean and regressed, re-installed.
Stem - Paint striped, painted, new decals and clear coat.
Bottom Bracket - Cleaned all the paint out of the threads, cleaned, new bearings, re-greased, and installed.
Cranks - The paint has worn through on these, so these got a repaint too. For anyone interested, Fiat Grove Grey is the closest match I could find to the SunTour XCD Grey.
Front Mech - Things started to get a bit silly here. After a strip and clean, I noticed a small scratch, so it got repainted too.
Rear Mech - Well I'd gone this far, so it got fully disassembled for a thorough clean and repaint (not quite finished yet).
Rear Shifter pod - I pulled this fully apart, removed all the old grease, and you guessed, it repainted it too.
The paint fumes started getting to my head, so I thought I had best call it a day there.
