Sunlite e81 Chain

Yes. While the e81 is engineered to withstand the higher torque of electric drivetrains, it is fully compatible with standard 7-8 speed bicycle setups.

This specialized surface treatment increases the hardness of the steel, which significantly slows down the rate of wear and helps the chain maintain its performance over a longer lifespan.

The e81 comes with 128 links, which is a standard length for most bikes. If your current chain is shorter, you can easily remove excess links using a standard chain tool to achieve the correct fit.

The outer plates feature a 4-edged chamfered design, which helps the chain move more fluidly between gears, resulting in smoother and more precise shifting.

Yes. The deep inner waist design is specifically engineered to reduce friction and noise, ensuring a quieter operation while you ride.

Sub-punched pins provide superior tensile strength compared to standard pins. This construction is crucial for e-bikes, where the chain must handle higher torque loads without stretching or breaking.
