Box Two P9 X-Wide Single Shift E-Bike Groupset
Our Box Two tier's mission in life is to deliver performance similar to the Box One but without its exotic (and costly) features. With the Single Shift E-Bike Groupset you still get the Tri-Pack™ Clutch in our derailleur only it isn't adjustable. The cassette's 12-50T range is optimized for E-Bikes. The action on the shifter is limited to one downshift per lever swing. The chain boasts the same unique ability to mate with a wide/narrow chainring except you give up the trick DLC top coat. You're hardly shortchanging yourself with Box Two.
