Description

The SHIMANO DEORE XT Di2 RD-M8150-SGS 12S Long Cage E-Bike Rear Derailleur combines Shimano's competition-derived expertise with a design specifically optimised for electric-assist mountain biking. Its full integration with SHIMANO e-bike systems guarantees smooth, reliable transmission perfectly suited to the high demands imposed by electric assistance, whatever the riding conditions.

Thanks to HYPERGLIDE+ transmission, this derailleur delivers fast, precise and continuous gear shifts, even under heavy load. FREE SHIFT technology allows the ideal gear to be selected without pedalling, facilitating transitions in corners or when the gradient changes, for better balance and optimal bike control.

Direct power from the STEPS main battery simplifies installation and ensures efficient energy management. Advanced connectivity allows settings customisation and system diagnostics via E-TUBE PROJECT, offering full control of the Di2 electronic drivetrain.

Equipped with SHIMANO SHADOW RD+ technology, the SHIMANO DEORE XT Di2 RD-M8150-SGS 12S Long Cage E-Bike Rear Derailleur benefits from a compact profile that promotes quiet and stable operation on rough terrain. Its long cage compatible with a wide range of sprocket sizes from 10 to 51 teeth guarantees maximum versatility for all electric mountain biking disciplines.
