To All of Our Amazing Customers: 
We would like to clear up some confusion about the future of our shopping center. 7 Mile Cycles is not being torn down, moving or closing its doors anytime soon! Our shopping center is going to be redeveloped and we will be moving into an all new space sometime in 2024!
We are very excited to see this project come together and look forward to our ALL NEW store!

BOX Two P9 X-Wide Single Shift E-Bike Groupset

BOX Two P9 X-Wide Single Shift E-Bike Groupset
126 Links
12 – 50T
Please select options


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.
