Here are a couple I have enjoyed. These are off the top off my head so forgive any slightly wrong authors or titles.
Will have a look later as I have loads of cycle books, mainly travel and road bio's type thing, not a huge amount of mountain bike stuff about.
Moods of future joys - Alistair Humphreys
Thunder and sunshine - Alistair Humphreys
Really good read, has a good site as well.
Discovery road - Andy Brown - great read about riding around the world
Why dont you fly - ? Riding from Beijing to UK
In search of Robert Miller - Richard Moore
Picked up a copy at the screening of Klunkerz at Fort William when Richard was showing Roberts old film and plugging the book. A really interesting read.
Bradley Wiggins Biography
Got this for Christmas and it was a really good read, a lot more interseting than I thought it would be.
Better stop there as the longer I do this the more that come to mind. Most of the mountainbike stuff is general type things.
Oh I nearly forgot my Stumpjumper 25 years, mine is signed by Mike Sinyard
Carlsberg dont build Singlespeeds but if they did.......they would probably look just like mine.
I've spent half my life on bikes.........the other half I wasted
