Adaptive Support that Reads the Rhythm and Terrain

AUTO ASSIST is designed to deliver the right level of support without asking the rider to constantly switch between modes. Using EP810's advanced sensor technology, the system tracks key ride inputs such as cadence and slope to understand how you are pedaling and how the terrain is changing beneath you. Set up AUTO SHIFT together with AUTO ASSIST, and you will be fully immersed into your ride. Shifting will be a thing of the past. 

Dynamic, Intelligent Support

Dive deeper into the technology.

 

AUTO ASSIST is part of the new TRAIL+ mode, creating a more natural and adaptive ride experience by continuously adjusting support levels in the background as terrain and rider input change. Using the SHIMANO CONNECT app, riders can choose their preferred default support level, while the system dynamically moves assist curves up or down to provide the right amount of assistance exactly when needed. Unlike standard TRAIL mode, which stays fixed within a single assist curve, AUTO ASSIST responds in real time to deliver smooth, intuitive power that keeps riders focused on the trail, not the settings.
