I have published three books that guide you through the process of choosing and specifying a bike - along with explaining the relevant decisions for major and minor component groups. The books also contain a series of worked example specifications to help you with your cost and weight planning.

If you are specifically interested in road bikes, then choose "How to Specify Your Road Bike".

If you are just considering mountain bikes, then choose "How to Specify Your Mountain Bike".

Or if you prefer a single book that contains all of the above (and also applies to hybrid bikes), then choose the more comprehensive "How to Specify Your Bike".
