E-bike Chain Length: 116 vs. 124 Links
Users on r/bikewrench frequently discuss the HG40 chain length for e-bikes, noting that 116 links may be sufficient even if original chains were 124 links, as manufacturers often use excess length.
Impressive Durability: 5000 Miles on HG40
A user reported approximately 5000 miles of use on their HG40 chain paired with an 8-speed Sunrace cassette and Shimano M310 chainrings, experiencing no breaks or skips, indicating robust longevity.
Value Choice for 7/8-Speed Upgrades
Discussions on r/TrekBikes and r/bikewrench suggest the HG40 as a budget-friendly option for 7-speed or 8-speed drivetrain upgrades or repairs on older bicycles.
HG40 Compatibility: Best for 7/8-Speed
Community members on r/bikewrench note that while the HG40 is compatible with 6-speed systems, it performs optimally with 7 and 8-speed HyperGlide cassettes for efficient shifting.
Expert answers based on real user experience
Many cyclists on platforms like r/bikewrench have noted that the 116-link Shimano HG40 chain is frequently used on e-bikes. Discussions indicate that original equipment manufacturer (OEM) chains on e-bikes can sometimes be excessively long, often exceeding 120 links. The community consensus suggests that 116 links is often sufficient for many 7-speed or 8-speed e-bike setups. While e-bikes generally require more solid components due to higher torque, users find this chain functional, advising to verify the actual length needed rather than relying solely on the original chain's length.

Reports from users on r/bikewrench suggest impressive durability for the HG40 chain. One user documented approximately 5000 miles of use with an 8-speed Sunrace cassette and Shimano M310 chainrings, reporting no instances of breaking or skipping. This longevity is notable when considering typical chain replacement recommendations, which often occur between 0.5% and 0.75% wear. The heat-treated rollers, pins, and plates of the HG40 likely contribute to its resilience under moderate riding conditions.
While generally reliable, there are isolated reports of a grinding sensation attributed to the Shimano HG40 chain, as noted on r/bikewrench. This issue, occurring on a new bike, was traced to the chain itself rather than a component like a bent derailleur hanger. Such problems could stem from very minor manufacturing inconsistencies in pin or plate tolerances, or less commonly, an incompatibility with specific chainring profiles or cassette spacing on a particular drivetrain. Proper chainline alignment and correct installation are crucial for smooth operation.

E-bike drivetrains typically generate higher torque levels compared to standard mechanical bicycles. While the Shimano HG40 chain features heat-treated components for durability, it was originally designed for traditional 6/7/8-speed applications. Dedicated e-bike chains often incorporate heavier-duty plating and more solid pin construction to manage the sustained, higher forces. Continuous operation under significant e-bike torque might lead to accelerated wear or a reduced service life for the HG40 compared to chains specifically engineered for electric assist systems, potentially impacting its performance over extended periods.
