I've picked up some more 'parts' in the last week. A Scott Aspect 45 from council cleanup, only needed a QR skewer in the front and some TLC. A giant roam with a badly dented frame, but otherwise near new parts to fix up son 2's bike that doesn't have any brakes at present and an old Avanti road bike to update to a new commuter and ditch the current flat bar.
The Scott looks pretty good for a 'camping' bike, but might look a bit too good for thieves.
All up the shed needs to shed about half a dozen bikes, and I'll need a few days worth of time to wrench the rest into shape.
I've got to stop looking at gumtree etc.
