💡 Why choose a bored to size type BS sprocket for your custom shaft setup?

A bored to size unit lets you lock the gear exactly to your existing shaft dimensions, which proves handy when stock sizes do not match your frame.
- Full depth keyway aligns on the centerline to handle peak torque without slipping
- Two setscrews clamp firmly against the hub to stop rotation during vibration cycles
- Accepts any shaft inside the range so you skip machining costs on the axle
