- Gear Material: Nylon gears with steel clutches balance durability and quiet operation; consider nylon for wear resistance and lighter weight.
- Replaceability: Look for kits that include bearings and necessary hardware to simplify installation and extend life.
- Noise And Vibration: Choose gear sets designed to minimize gear whine and chatter, especially for daily commuting.
- Weight And Durability: Aluminum-housed hubs offer lighter weight; nylon gears reduce wear but verify mounting strength for higher wattage systems.
- Maintenance Needs: Some kits require regular inspection of clutch engagement and gear wear; plan for periodic checks.
