Bike chain
Why We Focus on Bicycle Chains?
Because the bicycle chain is the soul of a bike’s performance. A great chain elevates every ride, and it’s our honor to provide reliable chains for cycling enthusiasts around the world.
Are your company’s chains easy to install?
Yes! Our chains are designed for quick and easy installation, compatible with most standard bikes.
Are your chains waterproof and rust-resistant? What about their quality?
Our chains feature excellent waterproof and rust-resistant performance, with high-strength, durable materials. Strictly tested for long-lasting use and stable riding.
Carbon Steel with an Oil-impregnated Surface, Effectively Reducing Friction
Carbon steel chains benefit from electrostatic polishing and hours-long high-temperature oil impregnation, resulting in excellent corrosion resistance and smoother lubrication. This ensures more flexible sliding performance and significantly reduces frictional resistance in each link, making riding more effortless.
More Compact Structure, More Efficient Power Transmission
After power transmission testing, we redesigned the internal structure of the bicycle chain to ensure it fits perfectly with the power transmission system. The chain is made of carbon steel and undergoes multiple oil bath forging and quenching processes, followed by salt bath treatment, resulting in a final tensile strength of 960 kgf.
Bike Link Plier
It can be used as both a chain main link remover and a connector, compatible with all speed chains and connectors.
Bicycle Chain Breaker
The head pin of this chain remover is made of ultra-hard steel, ensuring precise alignment and preventing bending or deformation during use.
2 Pairs Quick Buckle Connect
Seamlessly and quickly reconnects chain links. Maintains chain connection, securely holds the bicycle chain in place.
Bike Bell
Universal fit design suitable for most mountain bikes and road bicycles, making it an essential accessory for any rider.
