With smaller, sleeker hoods, the Shimano 105 2x11-speed compatible ST-R7025 STI with BR-R7070 caliper for hydraulic disc brake units deliver improved ergonomics for better rider comfort and control, with reduced lever stroke and lighter action.

Race proven performance: Shimano 105 2x11-speed ST-R7025 + BR-R7070 Disc Brake Set

The biggest innovation within the 105 group is undoubtedly the introduction of a group-integrated hydraulic disc brake system. The new BR-R7070 flat-mount calipers are compatible with ICE TECHNOLOGIES brake pads and UCI-compliant SM-RT70 (no 90-degree angle) brake discs, providing a high level of heat dissipation. The new ergonomic dual-control shift/brake levers (ST-R7020), which like the ULTEGRA ST-R8020 levers offer a larger adjustment range for different hand sizes and grip widths, represent the counterpart on the handlebars. For even more customisation options, the 105 R7000 Group offers an additional STI model (ST-R7025), which has been specially designed for drivers with small hands by changing the angle to the handlebars and outwards.

 

For both STI types - for rim brakes (ST-R7000) and disc brakes (ST-R7020/7025) - the shift mechanism has also been revised to ensure faster and smoother gear changes with shorter lever travel. 

 

Although the new SHIMANO 105 looks the same as its big siblings DURA-ACE and ULTEGRA in the same high quality sporty outfit, the developers for the R7000 group also considered that 105 users usually use their racing bike for much more than just racing or training. The SHIMANO 105 has always marked the entry into the field of high-quality, race-inspired component groups. With the new 105, this definition is now much broader and includes the high degree of user-friendliness and customizability required for a wide range of applications.

Technology:

STI Dual Control (DCL)

DCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from Shimano's MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration, and simply has to be experienced to be understood.

The Dura Ace, Ultegra and 105 Dual Control shift/brake levers have been optimised and feature, for example, a weight-reduced joint on the inside of the shift mechanism and integration of the cable for easier steering. The extremely compact and high-precision manufactured individual parts result in an unrivalled shifting speed.

 

Optislick

Optislick cables feature a minimal and uniform electrically coated layer that improves cable routing efficiency and provides excellent corrosion resistance.

 

One-Way-Bleeding

One-Way-Bleeding was developed for quick and easy prevention of air in Shimano's hydraulic system. They have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system.

One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.

 

Ice-Tech

Brake fading during prolonged uninterrupted operation, e.g. downhill, impairs braking performance. Shimano has introduced brake discs and pads with Ice-Tech technology to create a cooling technology for consistently high braking performance. The brake rotor has a three-layer stainless steel sandwich structure on the outside around an aluminium core. It radiates heat better and reduces a surface temperature from 400° C to 300° C, for example. The brake pads also have optional cooling fins. The design of the rotor in combination with the cooling fins results in a longer service life of the pads, less braking noise, less fading and a lower weight.
