Product Description

The Servo-Wave brake lever takes up a lot of braking distance at the beginning of its movement so that the pads can be guided to the brake disc with little lever travel. An elegant appearance and high-quality technologies distinguish Shimano's new SLX. The greater part of the lever travel is still available for increasing the braking force and metering more precisely.

One Way Bleeding
One Way Bleeding is designed to quickly and easily prevent air from entering the hydraulic system. Shimano has optimised the flow path of the brake fluid throughout the system to prevent air bubbles from settling in the system. The single direction pipeline path of the mineral oil together with the funnel for filling allows clean, problem-free venting.

E-Tube is a system platform for the Di2 concept (Digital Integrated Intelligence). E-Tube transmits interactive signals and supplies all electronic parts with power via "Plug & Play" connections. E-Tube is resistant to corrosion, expansion and frost and guarantees low maintenance. It offers optimal flexibility for your bike. With E-Tube Project you can customise the settings of electronic components and update the firmware via Windows PC or Tablet or Smartphone. It provides quick and easy access to information on electronic components and provides an immediate overview of the system status.
