The Complete Handbook of Bicycle Wheel Axles & Skewers

The humble axle and skewer is a safety-critical component that most riders rarely think about - until something goes wrong. This handbook is the first comprehensive, practical reference dedicated entirely to this often-overlooked part of the bicycle. It demystifies the alphabet soup of standards, from the classic quick-release to modern thru-axle formats like Boost and Super Boost, providing the clear, comparative data needed to make the right choice for any bike or riding style.

The book is structured to be used at the workbench, not just read. Early chapters explain the engineering and function of different axle types, bringing clarity to how they affect frame stiffness, wheel alignment, and even disc brake performance. It then provides decisive, criteria-based guidance for selection, considering factors like rider weight, frame material, wheel travel, and compatibility. Detailed installation and maintenance chapters give step-by-step procedures, torque specifications, and a troubleshooting guide to common problems like slipping skewers, seized thru-axles, and stripped threads.

A dedicated section on brands and suppliers dissects the market landscape, offering concrete business insights for shop owners and entrepreneurs - from the margins on premium versus budget parts to the operational advantages of stocking standardized thru-axle systems. The final chapters look toward the future of the category, examining emerging trends in materials and interface standards, and providing a curated guide to the expert resources and standards bodies every professional should know.
