ST-R7170 - Worry-free Di2 shifting in a compact shifter size
The new SHIMANO 105 shift/brake lever features Di2 electronic shifting for the first time, bringing precise, intuitive gear changes to even more riders. Reach adjustment and customized button functions allow you to dial in your ideal ergonomics.
BR-R7170 Disc brakes optimized for road riding
With proven hydraulic braking technology, the new SHIMANO 105 calipers feature the SHIMANO Flat Mount System and its low-profile design that is ideal for road bikes. More compact and lighter than ever, the R7170 brakes offer wide pad clearance for easy wheel removal and quiet performance as well as one-way bleeding for easy, clean maintenance.
ONE WAY BLEEDING
“ONE WAY BLEEDING” was developed for quick and easy prevention of air in our hydraulic system. Shimano has 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 TECHNOLOGIES
The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. SHIMANO has adopted ICE TECHNOLOGIES disc brake rotor and ICE TECHNOLOGIES pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.
