I see this thread has come back alive. At first, I had forgotten the thread, and I thought "Wonderful! I love cycling and I love books!". But, I had forgotten that I had already replied to this thread. Now, I will apologize for using the word "idiot" in my first reply to this thread, and to you. But the rest of what I said is still valid, and worth repeating. Forester is a must read for any serious cyclist, but I will qualify this to add, who grew up in a non-cycling country. In other words, probably every single person on this earth outside of the Netherlands, and maybe Belgium. I don't know about Belgium, never been there. But I know what Forester wrote is applicable in China - where bicycles were THE main mechanical transportation just a few years ago, and may still be.
But, maybe what you really want is books about bicycle racing. Not about bicycling? If that is that case, then say so. Don't beat around the bush. And change the title of the thread.
It's not just Forester, not at all. What about Kurmanskie? What about "Mom, Can I Ride My Bike Across America?" - I had to laugh at the person who said the would rather undergo torture before reading another Josie Dew book, but what about Josie Dew? She added significantly to the BICYCLING bookshelf. But she didn't add a jot to the BICYCLE RACING bookshelf.
You want to talk about cycling? Why not Jobst Brandt's book? For that matter, why not Sheldon Brown's html pages? They aren't a book, but they ARE reading material. Brings me back to this - are you asking for a bicycling bookshelf, or a bicycle racing bookshelf. A ton of difference.
