Chains, Chain Locks & Pins – The Connection Between You and the Drive
The chain - this metal part on the bike ensures that your leg power actually becomes forward motion. Whether cruising relaxed through the park or conquering sweaty climbs: The chain makes it possible. And to ensure it does this reliably, we have everything you need for maintenance, repair and upgrades.

Bicycle Chains: From 9-speed to 13-speed for every Drivetrain
9-speed to 11-speed Chains
The proven standards for mountain bikes, trekking bikes and road bikes. 9-speed and 10-speed chains are particularly robust and maintenance-friendly, while 11-speed systems already offer finer gradations and lighter construction. These chains are ideal for beginners and ambitious hobby cyclists.
12-speed and 13-speed Chains
The top class of modern drivetrain groups. These high-precision chains enable extremely fine gear gradations and are designed for maximum efficiency. They are used in high-end mountain bikes, gravel bikes and road bikes, where every gram and every gear step counts.
Important: The more gears, the narrower the chain. 13-speed chains are significantly more delicate than 9-speed versions and require more precise derailleur adjustment.
Chain Locks vs. Pins: The Evolution in Chain Technology
Pins – The Traditional Connection
Pins were the standard method for closing chains for a long time. A special bolt is pressed through the chain links and riveted. This connection is:
- Very durable and resilient
- Difficult to remove without special tools
- Usually only usable once
- Time-consuming when changing chains
Chain Locks – The Modern Alternative
Chain locks (also called Quick-Links or Master-Links) have largely replaced pins. These clever connecting elements consist of two interlocking parts that can be opened and closed without tools.
Advantages of Chain Links:
- Tool-free assembly and disassembly
- Reusable depending on manufacturer
- Quick chain changes possible
- Easy chain cleaning
- Just as stable as riveted connections
Why the replacement occurred: The main reason lies in practicality. Modern chains are changed and cleaned more frequently, especially with sporting use. Chain locks make these maintenance tasks significantly easier and faster. Additionally, they are just as safe as riveted connections when properly installed.
Waxed vs. Non-waxed Chains: The Difference in Detail
Non-waxed Chains
The standard variant comes lubricated with oil or grease:
- Lower purchase price
- Require regular re-lubrication
- Attract more dirt
- Proven, uncomplicated solution
- Ideal for casual riders
Waxed Chains
The premium option for efficiency enthusiasts:
- Treated with special chain wax
- Significantly lower friction resistance
- Stay clean longer
- Less wear on chain and cassette
- Higher purchase costs
- Special cleaning required
Performance difference: Waxed chains can improve efficiency by 2-5 watts – a measurable advantage for racers, more of a comfort feature for hobby cyclists.
Choosing the Right Chain for Your Bike
When selecting the appropriate chain, the following factors should be considered:
Compatibility: The derailleur determines the required number of gears. A 12-speed cassette absolutely requires a 12-speed chain.
Application: Mountain bikers benefit from robust 11-speed or 12-speed chains, road cyclists or gravel riders choose between 11-speed, 12-speed or 13-speed for optimal performance.
Maintenance effort: Waxed chains for performance-oriented riders, non-waxed for uncomplicated use.
Budget: Higher gear counts and wax treatment mean higher costs, but also better performance and longevity.
Why Quality is Crucial for Chains
A high-quality chain is an investment in the entire drivetrain group. Cheap chains wear out faster, stretch sooner and can damage expensive cassettes and chainrings. Brand chains from reputable manufacturers offer:
- Precise manufacturing for optimal shifting performance
- Longer durability
- Better corrosion resistance
- Smoother operation
