Detailed Analysis
Shimano Steps EP8 Compatibility
The EW-SS300 is specifically designed for use with Shimano's powerful EP8 drivetrain (DU-EP800). In this system, the speed sensor is one of the most important components in determining how much motor assistance to provide. Thanks to accurate data from the sensor, motor assistance is always at the ideal level.
Robust and Durable Platform
Developed with challenging roads and terrain conditions in mind, the sensor is resistant to impacts, mud, and water. It offers long-lasting and reliable performance even under the demanding conditions of MTB riding.
Compact and Low-Profile Design
The sensor's design is as simple and compact as possible to blend seamlessly with the bike's overall look. When mounted on the frame, it doesn't protrude much, offering a clean appearance.
Extra Space for Larger Tires
Thanks to improvements in its design, the sensor, when mounted on the chainstay, allows for the use of wider tires. This provides a significant advantage, especially in off-road e-bikes.
Chain Clamp Assembly
The sensor is mounted on the chainstay. A special mounting adapter (SM-DUE10) can be used for this. Thanks to this adapter, the sensor is securely fixed to the frame.
EW-SD300 Cable Compatibility
The EW-SS300 has been updated to work with Shimano's new generation slim cable system, the EW-SD300. These cables are thinner, making installation easier and offering a cleaner look.
Magnet set included.
The box contains the sensor as well as a set of magnets that mount to the wheel spokes. Speed and cadence data are obtained by the magnet passing in front of the sensor.
Cable Length Options
This product has a cable length of 340 mm. However, the following lengths are also available for different mounting requirements:
-
340 mm
-
540 mm
-
760 mm
-
1400 mm
When choosing the correct cable length, you should consider the size of your bike frame and the distance between the motor and the screen.
