The Shimano 105 BR-R7070 disc brake set with ST-R7020 - premium braking power and aerodynamics
The Shimano 105 BR-7070 disc brake set is a group-integrated hydraulic brake system with aerodynamic flat-mount calipers, which uses ice technology for optimal heat dissipation during the lower ring of the reumering and reterers. Bleeding makes proper ventilation easier. On the other hand, there are the STI shift / brake handles ST-R7020, which features a revised switching unit for intuitive and fast switching with less lever travel. They offer a larger setting range for different hand sizes and grip widths and really don't have to hide behind the Ultegra handles due to their refined ergonomics. The 105 dual control levers allow more control and reliable performance under all conditions when using disc brakes.

STI Dual Control (DCL)
DCL stands for Dual Control Lever. It has braking and switching functions and enables easy operation. The improved ergonomics is probably nomit wichitem the who the who the who the who the who the who the der der derbau so precise and smooth that it is possible to switch front and rear with just one finger. This is a highlight of Shimano's "Total Integration" (STI). To believe it, you just have to experience it yourself
The dual control shift / brake levers from Dura Ace, Ultegra and 105 have been optimized and feature, for example, a weight-reduced joint on the inside of the shift mechanism and integration of the shift cable for easier steering. The and zorzine zigger zipper unmatched switching speed.

Optislick
Optislick trains are provided with a minimal, uniform galvanic coating, which enables more efficient cable routing and is characterized by excellent corrosion resistance.

One-way ventilation
One-way ventilation has been developed to quickly and easily prevent air from being in the hydraulic system. Shimano has optimized the route of the brake fluid in the entire system in order to use it
The brake fluid conduction path in only one direction, together with the funnel for filling the mineral oil, enables clean, problem-free bleeding.

Ice tech
Fading the brake after prolonged uninterrupted operation, for example when driving downhill, affects the braking performance. Shimano has brake discs and brake pads with Ice-Tech Technoististe from Brechle ärger schleichers szr. outside around an aluminum core. It radiates heat better and, for example, reduces a surface temperature from 400 ° C to 300 ° C. In addition, the brake pads optionally have cooling fins. The construction of the Schung with drerk d'Urben, less braking noise, less fading and a lower weight.```
