If one of your main points of contact between you and your bike employs ergonomics as its guiding design principle, then the way you shift and brake should feel smooth and precise, as well as respect your natural riding position. UNO´s shifter/brake levers took their design cues from coveted characteristics like single-lever shifting, precision actuation, carbon fiber craftsmanship, and uncompromised ergonomics to yield shift/brake levers that respond to your direct command.
