SHIMANO STEPS SM-CRE70 E-Bike Chainring (34T)
Elevate your electric mountain bike´s performance with the genuine SHIMANO STEPS SM-CRE70 Chainring. Engineered specifically for the high-torque demands of modern E-bikes, this essential drivetrain component ensures flawless power transfer, exceptional durability, and the seamless integration you expect from Shimano. Whether you are replacing a worn part or upgrading your ride, the SM-CRE70 is the definitive choice for riders using Shimano STEPS E7000 and E8000 motor systems.
Designed to conquer challenging trails, this chainring is optimized for E-MTB applications. It is built to withstand the increased forces generated by the pedal-assist motor, providing a stable and reliable connection between you, the motor, and the trail. The robust steel construction guarantees a long service life, resisting wear and tear from thousands of high-power pedal strokes in all weather conditions. This focus on durability means you can ride with confidence, knowing your drivetrain is up to the task.
A standout feature of the SM-CRE70 is Shimano´s proprietary DYNAMIC CHAIN ENGAGEMENT+ technology. This special gear tooth profile is meticulously designed for single-chainring setups, delivering superior chain retention and smoother, quieter pedaling. On rough, technical terrain where chain security is paramount, this technology actively grips the chain, drastically reducing the risk of drops and ensuring your power is consistently delivered to the rear wheel. This means more focus on your line and less worry about your drivetrain.
The 34-tooth configuration offers a versatile gear ratio, perfect for all-around trail riding. It provides an excellent balance for tackling steep, technical climbs without sacrificing speed on flatter sections and descents. Paired with a wide-range cassette, the 34T SM-CRE70 allows you to maintain an optimal cadence, maximizing both your own effort and the motor´s assistance for greater efficiency and range.
This chainring is designed for broad compatibility within the Shimano ecosystem, making it a straightforward and reliable upgrade. It is fully compatible with 9, 10, and 11-speed drivetrains, allowing for flexible setup options. The 104 mm BCD (Bolt Circle Diameter) is a standard 4-bolt mounting pattern, ensuring easy installation on compatible crank arms. Furthermore, its 53 mm chain line is perfectly aligned for modern E-MTB frames, including those with Boost hub spacing, guaranteeing optimal shifting performance and reducing drivetrain wear.
Choose the SHIMANO STEPS SM-CRE70 chainring for uncompromising quality and performance. It is the official, purpose-built component designed to work in perfect harmony with your Shimano E-bike system, delivering the reliability and ride quality that defines the Shimano brand.
