Technologies
Shimano Shadow RD
With its sophisticated technology, SHIMANO's SHADOW rear derailleur is particularly suitable for a more aggressive riding style. The extremely minimized profile brings a number of advances. Thanks to its flat design and single bias construction, the rear derailleur doesn't hit the chainstay even in the toughest conditions. Gear shifting works cleanly and quietly.
SIX SHIMANO INTELLIGENT ELECTRONIC SYSTEM
The innovative shifting technology of the SEIS continues to be based on the SHIMANO INDEX SYSTEM (SIS), whose superior shifting performance has been proven for many years. The main difference between the systems is that the shifting process is no longer mechanical, but electronic.
There is no effort required to change gears, which brings significant benefits as the rider always has a firm grip on the handlebars and can concentrate on driving without being distracted by changing gears. The gear change system allows precise and effortless shifting in any situation, even with cold hands or when the rider is completely exhausted.
Shift performance can no longer be affected by dirty or stretched cables as the shift signal is transmitted electronically. The control buttons work similarly to mechanical dual-control sticks, making the SIX easy to get used to.
E Tube
The E-Tube platform offers optimal flexibility. The E-Tube transmits interactive signals and powers all parts through "plug & play" connections. The E-Tube is resistant to corrosion, expansion and frost, and guarantees low maintenance.
