•Material: Steel
•Single-Speed or Fixed-Gear Bikes: Typically use shorter chains (around 98 to 110 links), depending on gear ratios.
•Multi-Speed Bikes (Derailleur Systems): Usually require longer chains, typically 110 to 126 links, because they need to accommodate a range of gears. If you use a chain that's too short, it may not shift properly or could damage the derailleur.
•Road Bikes: Around 110–114 links
•Mountain Bikes (MTB): Around 116–126 links
•BMX: Typically 98–104 links
•Kids’ Bikes: Usually shorter chains, around 86–100 links
•If you have a single-speed or BMX bike, a 98-link chain may work.
•For multi-speed bikes, you might need to add extra links or get a longer chain.
