FIT Bike Co Key Drive Sprocket – 24mm Spline Drive (25,28t) BMX Chainrings
FIT Bike Co Key Drive Sprocket – 24mm Spline Drive
Product Overview
The FIT Key Drive is a spline drive sprocket machined from 7075-T6 aluminum for lightweight strength. Designed exclusively for 24mm, 48-spline cranks, it features offset teeth for improved chain alignment and a chromoly spline insert for durability. Available in 25T and 28T sizes with a signature arrow-style cutout design.
Key Features
- CNC-machined 7075-T6 aluminum – Aircraft-grade aluminum alloy provides high strength-to-weight ratio; CNC machining ensures precise tooth profiles and tight tolerances for accurate chain engagement
- Chromoly spline insert – Steel insert in the spline interface resists wear from crank spindle contact better than aluminum alone, extending sprocket life
- Offset 1/8" teeth – Teeth are offset to improve chain alignment and reduce lateral movement, resulting in smoother drivetrain operation and reduced chain wear
- Split four-spoke design with arrow cutouts – Weight-reducing design inspired by the FIT Key logo removes material where it's not needed while maintaining structural integrity
- 24mm, 48-spline specific – Engineered to work exclusively with 24mm spindle diameter, 48-spline cranks for secure fit and power transfer
- 6mm thickness – Standard sprocket thickness provides durability without excess weight
Technical Specifications
- Teeth options: 25T, 28T
- Chain compatibility: 1/8"
- Bore: 24mm, 48-spline
- Thickness: 6mm
- Material: 7075-T6 aluminum body with chromoly spline insert
- Construction: CNC-machined
- Weight: 2.8 oz (25T)
- Design: Split four-spoke with arrow-style cutouts
Compatibility and Ideal Use Cases
Compatible exclusively with 24mm, 48-spline cranks (not compatible with 19mm, 22mm, or other spline counts). Works with 1/8" BMX chains. The 25T option provides quicker acceleration and easier technical riding, while the 28T offers higher top speed and more efficient pedaling for racing or faster riding. Offset teeth improve performance across street, park, and flatland applications by reducing chain noise and wear. Suited for riders seeking a lightweight, durable sprocket with precise engagement.
