Starting in July of 2024, SRAM began updating the markings on our 12-speed chains. This update aims to make the model codes uniform in size across all models and make them easier to read. This change began with our road 12-speed Flattop chains and Eagle Drivetrain chains and our Eagle Transmission chains will be updated to the new markings by the end of 2024. Due to the large number of chains we make each year, it will take some time for these new chains to consistently show up in inventory, so a shop or retailer can have both versions in stock at the same time.
What changed?
The model code (D1 or E1) was moved from the edge to the middle of the outer plates. The SRAM logo was updated, and T-Type chain models now feature a larger model mark (GX, X0, XX). This update does not affect chain performance, and the part numbers will remain the same.
Please see the images below to see what the new marks look like. Note that the outer chain plates will carry one of several markings: SRAM, chain series name, model code, or a three-digit manufacturing code.
That’s fine, but how can I tell if it is counterfeit?
You have nothing to worry about if you purchased your chain from a reputable SRAM dealer! If you bought it from a less-than-reputable online seller for a price that seems too good to be true, it is probably worth having the chain evaluated in person at your local SRAM dealer to ensure it isn’t counterfeit.
