Unleash Peak Performance with Advanced Shimano Technology
The core of the SM-CRE70-B´s exceptional performance lies in Shimano´s groundbreaking Dynamic Chain Engagement+ (DCE+) technology. This special gear tooth profile is meticulously designed to provide superior chain retention, smoother pedaling, and increased durability. The narrow-wide tooth pattern securely grips the inner and outer plates of the chain, drastically reducing the chance of chain drop, even when navigating the roughest terrain. This gives you the confidence to push your limits in demanding MTB Cycling conditions without hesitation. The result is a quieter, more efficient drivetrain that translates more of your power—and the motor´s assistance—directly to the trail.
Optimized for Modern E-MTB Drivetrains
Shimano´s SM-CRE70-B chainring for STEPS E7000 E-MTB drive system features a modern design for 9/10/11-speed drive units. Its versatile compatibility makes it an ideal choice for a wide range of setups, whether you are running a robust 9s system, a versatile 10s drivetrain, or a wide-range 11s cassette. While this chainring is specifically optimized for these systems, it is part of Shimano´s comprehensive MTB component family that supports everything up to the latest 12s drivetrains. The design features a 53 mm chain line, perfectly calibrated for modern E-MTB frames with Boost hub spacing. This precise alignment ensures smoother shifting, reduces drivetrain noise, and minimizes wear on your chain and cassette, prolonging the life of your entire system.
Built on the proven and robust 104 BCD 4-arm mounting standard, this chainring offers a stiff and reliable connection to your crankset, a trusted industry standard known for its strength and wide compatibility, providing a powerful alternative to Direct Mount systems. Its sleek, modern aesthetic seamlessly integrates with the look of your Shimano STEPS motor, enhancing the overall appearance of your bike.
