The new wireless Di2 platform ensures fast and smooth shifting at the front derailleur. It also offers a choice between manual shifting and synchronised shift assist modes - SEMI-SYNCHRO or FULL-SYNCHRO - that feel like your own personal assistant! In SEMI-SYNCHRO mode, the rear derailleur automatically adjusts to avoid big jumps in gear ratio so you can maintain your cadence and rhythm. In FULL-SYNCHRO mode, the rear derailleur and front derailleur work together harmoniously so that you always have the right gear engaged and no longer have to worry about it. Seamless communication with the rear derailleur combined with programmed chain guide control minimises the risk of the chain jumping off. The maximum number of teeth is 50-52. It's up to you how often you want to think about the gear ratio!In the E-TUBE app, you can select the fully and semi-synchronised shifting functions. Thanks to the digital precision of the electronic shifting and its coordinated communication between the front and rear derailleurs, the SHIMANO 105 front derailleur offers an excellent shifting experience.Features

Technologies
SEIS SHIMANO ELECTRONIC INTELLIGENT SYSTEMThe SEIS innovative shift technology is still based on the SHIMANO INDEX SYSTEM (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances like 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 Levers so you don’t need to re-program your mind for a new system.
E-Tube
E-Tube platform offers optimum flexibility on your bike. E-TUBE transmits interactive signals and power supply to each parts by “Plug & play” connection. E-TUBE is no rust, no stretch, no freeze and it ensures advanced low maintenance. And SM-PCE1 connects between PC and components to update firmware. Digital device stay the latest version with updating firmware for improve function.
HOLLOWGLIDE - Hollow technology on outer chainring
High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting.
HOLLOWTECH II - Providing the best balance of stiffness, strength, weight and rotating performance

HOLLOWTECH II - Providing the best balance of stiffness, strength, weight and rotating performance
The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.
Shimano Shadow RD
The mechanism rear derailleur, SHIMANO SHADOW RD, is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
