MARS cassettes and freewheels offer superior shifting performance and outstanding quality. They are designed to achieve more comfortable, faster and smoother riding. End saw that is computer designed combines specific ramps with individually angled teeth for smooth and instant drivetrain engagement.

On conventional cassettes and freewheels, the chain can "ride up" during gear change. MARS cassettes and freewheels ease the chain into the right gear quickly and smoothly, so there is less noise and friction, reducing wear on the chain.

MARS cassettes and freewheels' spacing matches exactly that of ISO standard drivetrain components, designed to mount on ISO standard compatible freehubs.

MARS cassettes and freewheels offer high strength and durability. Our tensile test shows that MARS 11 tooth can withstand a load of over 917 kgs, and still maintain in good condition. This is more than the standard 11 tooth can endure. Each MARS cog is able to withstand more than 1550 pounds of force.

With a variety of gear ratios available, cyclists will easily find a cassette sprocket that suits their requirements. If you have special requests on the combination, just ask us. We will do our best to fulfill your needs.
