STEP 1: How To Shift
Your righthand Apex shifter uses DoubleTap technology to shift your rear derailleur with a single paddle. It handles up and downshifts in one short sweeping motion, with minimal effort and maximum comfort no matter where you are on the bars.
To shift into a harder gear, push the shift lever one click. This is known as upshifting. Shifting to easier gears, or downshifting, takes two or more clicks. You can even downshift multiple gears at once with one sweeping push of the lever.
