Active Junky’s been cross-referencing this 600-illustration volume for years. We’re not alone as this guide is the world’s best-selling book on the topic. Here’s an insider’s tip; buy the book before you get a bike to see what’s involved with each component category including brakes and forks. Over 450 pages of practical ideas make Zinn’s work a must-have from a cycling fanatic who rides and lives the two-wheeled mindset. Anticipate problems but be ready to escape them with some sense of style and artistry thanks to your new best friend Lennard.
