Bicycle hub conversion adapters for front and rear hubs - Precision CNC machining yields a smooth exterior surface, reducing the risk of abrasion to other components and frame contact. - Aluminium alloy construction provides high strength, rust resistance, and resistance to deformation for reliable performance. - Includes all necessary assembly hardware, making installation straightforward and user friendly for easy hub conversion. - Front hub conversion from 100 x 15 mm to 110 x 15 mm; rear hub conversion from 142 x 12 mm to 148 x 12 mm to broaden compatibility with modern through-axle standards. - Designed for cycling enthusiasts who want flexible hub compatibility without replacing wheels, enabling efficient upgrades and maintenance. Typical use scenarios - Upgrading an older wheelset to fit a modern through-axle frame: convert the front hub to 110 x 15 mm and the rear hub to 148 x 12 mm to compatible standards. - Reusing existing hubs across different bikes with varying axle standards: swap between 100 x 15 mm front and 142 x 12 mm rear setups to match frames or forks. - Maintaining or preparing multiple bikes for travel or seasonal use: keep spare adapters on hand to quickly adjust wheelsets for different bikes without purchasing new hubs.
