Well, as the OP and seeing as we're all jumping on the band wagon again....
A GT hubbed front wheel in a box that's proved too pricey to send to Spain, so it's waiting to go back out in the work shop where everything else now is. Apart from the 'dale frame that lives on top of the wardrobe still....
I have an early 90's kona dog collar on the coffee table with no kona to put it on.
I also have a shimano saint hollowtech bottom bracket and park removal tool still in there packets
Sbike fully frame on the wall and a RD-M735 next to the PC screen.
Oh ... does a bottle count as a "bike bit" ?
At my 7 o' clock :
The Sbike may be a piece of art, but TBH this is no place for it. It should be tearing up the streets, not hanging on a wall like a mere Van Gogh.
However as long as I don't get round to fixing/replacing the freewheel, it's not going to get ridden anyway.
