Here is what Chris Brigham from knifeandsaw says about this shelf on his site:
While visiting many friends small apartments here in SF and more so in NY, I noticed that there is a void when it comes to elegant bike management. Bikes always get in the way – either in the hall, or leaning up against a bookshelf or something. So, I decided to design something to fix that problem. Until I think of a better name, I am calling it the Bike Shelf.Email him for inquiries or orders. The walnut version is 300$ and the ash versions costs 270$!
