The Ritchey 15 mm Thru-Axle Conversion Kit transforms compatible quick-release wheels or frames to accept a 15 mm thru-axle setup, combining added stiffness and alignment precision with rugged reliability. Thru-axles offer improved wheel retention and frame-wheel interface stiffness over traditional QR skewer systems, which can enhance handling, braking consistency, and overall ride confidence — especially under load or on rough terrain. This conversion kit lets you upgrade to that performance standard without needing to replace your hubs or wheelset outright.

Precision-machined from durable materials, the kit includes the necessary thru-axle hardware and adapters you need to install into compatible forks or rear stays. The 15 mm specification is a widely adopted standard in modern mountain and gravel frames, balancing strength and weight for a wide range of riding styles. Once installed, the thru-axle engages cleanly with the dropout interfaces, holding the wheel firmly in place and minimizing flex or torque under pedaling and braking forces.

Installation is straightforward with common tools, and the parts are engineered to fit snugly and securely, promoting reliable engagement and easy wheel removal when needed. For riders looking to enhance frame stiffness and wheel stability without a full hub or wheel overhaul, the Ritchey 15 mm Thru-Axle Conversion Kit provides a practical, performance-oriented upgrade path.
