2016 On One Parkwood 29er Frame, Medium BNIB, Black/Yellow.

Brand new, still in the box On One Parkwood 29er Medium frame. Bought because I was going to do the same as them and build it into a 650b+ bike. Ended up buying a complete bike (the Trek Stache), and so it's sat in it's box. I've got the original paperwork in the box too.
Have a look at the On One Parkwood 27.5 bike for what headset to spec, although I'm running the FSA equivalent Brand X headset (cost £13) on my other On One with no problems:

Some cheap parts, whatever you've got laying in the shed, and you should have a cheap ripper to ride around and thrash on! They're really good budget bikes.
£70 collected.
