With smaller, sleeker hoods, the Shimano 105 STI ST-R7025 (for small hands) adds an extra bonus in combination with the hydraulic disc brake, feature improved ergonomics that not only increase comfort, but also improve control.
Race proven performance: Shimano 105 11-speed STI Dual Contral ST-R7025 right for Hydraulic Disc Brake
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.
