book introduced me to aspects of city cycling I was just blindly searching for on my own.
There are many resources on cycling. Often they turn up to be revolving around road cycling or mountain cycling.
This one is for daily city commuting. Very practical in this regard. Title is suggesting it is specific to London, but I believe that many cyclists living in some European cities may find it useful as well. For London the book contains shop addresses, websites and other specific data.
