Description
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. The braking range has also been extended for improved control.
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
