From chain pitch to cassette ratios, this handbook is the definitive, unbiased reference for understanding, choosing, installing, and maintaining every part of the bicycle drivetrain.
About this book
Bicycle drivetrains are a world of precise tolerances, shifting standards, and brand-specific quirks. Whether you are a shop mechanic rebuilding a customer's bike, a fleet manager standardizing maintenance, or an enthusiast building a dream machine, getting the drivetrain right is critical. This handbook strips away the marketing hype and delivers the technical reality. It explains how each component—from the crank arm to the rear derailleur pulley—functions within the system, and why the specifications matter in the real world.
The book is structured for practical use. Early chapters give you the foundational knowledge and a decision-making framework for choosing the right parts for specific riding styles and budgets. Subsequent chapters walk you through installation, setup, and the day-to-day maintenance that keeps a drivetrain running flawlessly. You will learn how to diagnose and fix the most common failures, from chain skip to ghost shifting. Later chapters offer an unvarnished look at the market landscape—who the major players are, how they are positioned, and where the realistic business opportunities lie for those looking to service, sell, or even private-label drivetrain components.
Written with a neutral, instructional voice, this is not a promotional brochure. It is a manual built for the workbench and the reference shelf. It covers both the established standards that still dominate the market and the new technologies—like electronic shifting and 1x systems—that are reshaping the industry. With clear explanations, concrete examples, and a full glossary and FAQ, it is the single resource you need to make informed drivetrain decisions and get the most from the parts you choose.

★★★★★Finally, a book that treats a drivetrain like an engineering system instead of a collection of mystery parts. The chapter on types and specs is worth the price alone - I finally had the BCD and chainline rules spelled out clearly for a custom build I was planning. I docked it a star because the section on electronic shifting felt a little thin given how fast that tech is moving, but the mechanical stuff is spot on.

★★★★★It's a solid reference, don't get me wrong, but I was hoping for a little more depth on the business side, since that's the chapter that caught my eye. The chapter on brands felt a bit like a list - it told me who the players are but I wanted more analysis of their actual supply chains. For the purely technical maintenance sections, however, it's exactly what it claims to be, and that part gets five stars from me.

★★★★★As a mechanic at a busy shop, I thought I knew most of this. This book proved me wrong, or at least tidied up a lot of the 'it works if you do it this way' folk knowledge I'd accumulated. The chapter on installation and usage is now my go-to reference for young mechanics I'm training. It's clear, direct, and accurate. I've already bought two more copies for the shop floor.

★★★★★Good, sturdy reference material. I especially appreciated the neutrality in describing different brands - it's obvious they weren't paid off by anyone. The troubleshooting chart in chapter five helped me fix a stubborn indexing issue on an old mountain bike. My only real complaint is the paper quality; the book is going to be used in the garage, and I'm not sure the cover will survive a season of grease and grime.
Jonathan Brown
★★★★★This has become my pre-purchase bible. The decision framework in chapter 3 is practical and - more importantly - it's based on performance and longevity, not hype. I used it to spec a commuter build that's been flawless for 2000 miles. It's a little dense to read cover to cover, but as a reference to dip into when you're planning a project, it's invaluable.
Nicholas Rodriguez
★★★★★It's very thorough, though perhaps a bit too thorough for a casual rider. I bought it because I wanted to understand the 1x vs 2x drivetrain debate on gravel bikes. I got my answer, and then some. The chapter on future trends was interesting but a bit speculative in places. It reads more like a textbook, which is good or bad depending on what you're looking for. I was looking for a quicker read, so it's three stars from me, but I'll keep it on the shelf for when I need to fix something.
