Over 400 pages of A-Z entries about all things cycling. It's fascinating to dip into with encyclopaedic entries for subjects like Derailleur, Derny, Desgrange, Dogs (the cyclist's curse), Dolomites (Giro routes and sportives), etc. Entries are for cyclists, races, cycling manufacturers, cycle types and parts, etc. However, it's a great shame that at first sight, many words appear to be completely missing. The publishers decided to print key words (which have their own entries) in yellow! There are also panels printed yellow on yellow! It's difficult to comprehend that such a good book should be spoilt in this way. Therefore, a potential 5* reduced to 4*.
