Chain drive
- The most common system. It is light, efficient and easy to replace.
- It needs regular cleaning, lubrication and tension adjustment.
- Chain and sprockets wear and are usually replaced together.
Shaft drive
- A sealed shaft runs from the gearbox to the rear wheel.
- It needs very little attention, apart from occasional gear oil changes in the final drive.
- It is heavier, a little less efficient, and can make the bike react a little when you open or close the throttle.
Belt drive
- A toothed rubber belt reinforced with fibres, quiet and clean.
- It needs no lubrication, but should be checked for damage and correct tension.
- Stones and sharp objects can damage it, and it can be costly to replace.
Which one is for you?
If you do a lot of distance, or want low upkeep, shaft or belt may suit you. If you like light weight and are happy to do a few minutes of care each week, a chain is a good choice. In every case, following the maintenance in your manual is what keeps the drive working.
If you ride a chain bike, see chain care. A worn or loose chain is a safety issue, so have it checked if you are unsure.
