For Sale: Bike shelf

I just realise a huge disadvantage to that bike shelf thing.

1 - it'll be likely to placed higher up making it a tad diffcuilt to reach books.

2 - if your top tube is shorter than the bicycle in picture, you're fucked (although the bloke did says he'll customised it to fit your bike).

Ha, and i can't help thinking that it would just be a whole lot easier to fix some hooks to the underside of a 'normal' shelf?

Maybe i'm missing something.
