Project RatBike is done!
Took advantage of Mrs. Hall being away and dragged workstand, bike and misc tools into the kitchen, wot is warm.
Fitted brakes (well done APC, Spa Cycles carrier of choice, for having the smarts to leave them with a neighbour when I was out), fettled brake cables to length. Fitted black mudguards, black bar tape, black seat post, rear light (red), old bar bag (black) and front light.
It works.
I may ride it to work tomorrow.
