SEIS SHIMANO ELECTRONIC INTELLIGENT SYSTEM

seis

DI2コンセプトをベースにシフティングシステムをコンピュータ制御する技術革新。これはSEIS (シマノエレクトロニックインテリジェントシステム)と呼ばれています。
The shift system allows accurate and effortless shifting in difficult circumstances for example when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical DUAL CONTROL LEVER so you don’t need to re-program your mind for the SEIS.
