Fit Bike Co RHD Cassette Hub 10T 14mm Axle

Product Overview

The Fit Bike Co RHD Cassette Hub is a sealed-bearing rear hub with a 10-tooth driver and 14mm axle designed for reliable performance across multiple wheel sizes. The larger 10-tooth driver works efficiently with 28-tooth and larger sprockets on 20″ bikes while remaining versatile enough for 22″ and larger wheels with various gear ratios. Built with matte black aluminum and sealed cartridge bearings for durability and low maintenance.

Key Features

• 10-tooth cassette driver – Larger driver teeth reduce wear and improve chain engagement compared to 9T drivers, especially when paired with 28T+ sprockets
• Sealed bearing design – Cartridge bearings keep dirt and moisture out, extending service life and reducing the need for frequent maintenance
• 14mm heat-treated axle – Thicker axle diameter (180mm length) provides increased strength and stiffness compared to 3/8″ axles, reducing flex under pedaling loads
• 36-hole drilling – Drilled for 14-gauge spokes, offering compatibility with most standard BMX rims and spoke configurations
• Right-hand drive configuration – Driver mounts on the right side for conventional drivetrain setup used by most riders

Compatibility and Ideal Use Cases

This hub fits frames with 110mm rear dropout spacing and 14mm axle slots, which is standard on most modern street, park, and dirt BMX frames. The 10-tooth driver is ideal for riders running 28-tooth or larger sprockets who want better gear efficiency and reduced driver wear. Also well-suited for 22″ and larger wheel builds where the 10T driver provides appropriate gearing across a wider range of sprocket sizes. Best for riders who prioritize durability and low maintenance over ultra-light weight, or anyone upgrading from a 3/8″ axle setup to a stronger 14mm system.
