I am fairly new to mountain biking (riding one season before reading the book) and found almost all of the tips and instructions very helpful. I used many of the tips this season (my second) and found I am a much better rider now. I plan to go back and reread the entire manual now because it is written for every skill level, so some of the things that were over my head I think I will now understand. I strongly recommend this book to anyone who isn't an expert already.
