The Shimano ST-R8170-L J-kit Brake caliper brings a new level of control to the road bike world with optimized modulation and unmatched stopping power. New design minimizes brake judder. Additionally, despite its compact size, the system is quieter and easier to maintain than ever before.
Switching commands are forwarded without cabling. Wireless technology with a transmission protocol specially developed for this ensures the fastest switching process previously impossible in the bicycle sector.
With the push of a button, your gear connects quickly and securely. A precise pressure point on the lever ensures that the shifting process is actually triggered only when the driver makes a conscious shift. Accidental activation should not be feared.
