Key benefits Faster wheel removal and installation: the smooth cam lever gives quick, tool-free assembly and disassembly while maintaining a secure hold between axle and frame. Reliable, long-lasting parts: robust steel construction and durable hollow design resist everyday wear and preserve performance over time. Easy retrofit to quick-release style: convert standard solid axles into hollow quick-release-capable axles (quick release parts not included) for simpler maintenance and wheel changes. Clear compatibility: front axle approx. 107 mm and rear axle approx. 144 mm — suitable for bicycle frames and models that accept these lengths. Product features Smooth cam lever: engineered for easy operation and a secure clamping action that prevents accidental loosening during rides. Hollow steel axles: solid, durable hollow construction that accepts quick-release components for conversion without replacing the entire hub. Front and rear included: one front axle (~107 mm) and one rear axle (~144 mm) supplied in the package. Durable steel material: designed to withstand regular use and maintain functionality under typical cycling conditions. How this solves common problems Eliminates slow, tool-dependent wheel changes by enabling quick lever operation. Extends the life of existing hubs by allowing conversion to a quick-release setup without full hub replacement. Provides a secure connection that reduces the risk of axle slippage or loosening on rides. Compatibility and installation notes Check your frame and hub spacing to confirm compatibility with the listed axle lengths: front ~107 mm, rear ~144 mm. Quick-release components (skewer and nuts) are not included; you will need compatible quick-release parts to complete a retrofit. Intended as direct-replacement axles for compatible bicycle models that accept these dimensions. Practical use scenarios Commuter bikes: swap wheels at home or on the go for faster repairs or to remove a wheel for compact storage on trains or in tight spaces. Workshop maintenance: mechanics and home mechanics can convert older solid-axle hubs to accept quick-release skewers for easier routine servicing. Event or race prep: quickly change tires or inner tubes between stages or before a ride without carrying extra tools. Specifications summary Cam lever: smooth operation for quick assembly/disassembly Material: robust steel, hollow construction Package: includes front axle (~107 mm) and rear axle (~144 mm) Note: quick-release components not included; suitable for frames/hubs matching the axle lengths If you are unsure about fitment, measure your current hub spacing and axle dimensions to confirm these axles are compatible with your bicycle.
