A strong choice for riders replacing a worn 12-speed SRAM T-Type chain, especially trail and E-MTB riders who want solid-pin durability with a PowerLock connector included.
The SRAM Eagle 70 Transmission Flattop Chain is a 12-speed mountain-bike chain built for SRAM T-Type drivetrains. Its Flattop profile and smooth-shift bottom profile support clean, precise gear changes across Eagle Transmission systems, while the polished steel finish gives it a distinctive grey-and-black appearance.
For demanding trail and E-MTB riding, the chain uses solid pins and a robust construction designed to handle the higher loads associated with electric mountain bikes. It is fully approved for E-MTB use, making it a practical choice when durability and dependable shifting matter more than saving every gram.
This chain is compatible with the Eagle 70 Transmission derailleur and other T-Type Transmission components, including SRAM AXS Transmission systems. The included PowerLock 12s T-Type connector lets you join the chain without a separate connecting pin, so you have the key fitting component included in the box.
