Technologies

Shimano Shadow RD+
Smooth operation and reduced vibration. The rear derailleur stabiliser minimises chain slap. A simple solution to prevent the chain from coming off. Lighter and more efficient than chain guides with rollers.

SEIS SHIMANO ELECTRONIC INTELLIGENT SYSTEM
The innovative shifting technology of the SEIS continues to be based on the SHIMANO INDEX SYSTEM (SIS), whose outstanding shifting performance has been proven over many years. The main difference between the systems is that shifting is no longer carried out mechanically, but electronically. This electronic gear-changing system has been extensively tested in recent years by several professional cyclists under every conceivable condition, e.g. in the rain, mud, extreme cold, on cobblestones and even when these factors are combined. Shifting is carried out at the simple touch of a button. No physical effort is required to shift gears, which offers significant advantages, as the rider maintains a firm grip on the handlebars at all times and can concentrate on riding without being distracted by the shifting process. The gear-changing system enables precise and effortless gear changes in all situations, even with cold hands or when the rider is completely exhausted. Furthermore, gear-changing performance can no longer be impaired by dirty or stretched cables, as the gear-changing signal is transmitted electronically. The control buttons operate in a similar way to mechanical dual-control levers, making it easy to get used to the SEIS.

E-Tube
The E-Tube platform offers optimum flexibility. E-Tube transmits interactive signals and supplies power to all components via ‘plug-and-play’ connections. E-Tube is resistant to corrosion, stretching and frost, and ensures low maintenance. The SMPCE1 establishes the connection between the PC and the components to update the firmware. Digital devices remain up to date through firmware updates and offer improved performance.
