The new wireless brake shifter has been revised in collaboration with professional riders and impresses with outstanding ergonomics thanks to its raised horn and lighter lever actuation. The grip width adjustment mechanism allows adaptation to a wide range of hand sizes and riding styles. In addition, the braking range has been extended for improved control.
The new hydraulic brake calliper has a 10 % wider pad spacing than the mechanical 105 model, resulting in less brake friction and therefore less noise. In addition, less maintenance is required due to the bleeding process.
10% wider brake pad spacing reduces the likelihood of dragging brake rotors
Up to 3 years of battery life with easily replaceable CR1632 batteries in the shift/brake levers (included)
The E-TUBE APP makes it easy to change the button function
