My 13 t sprocket is working really nice for getting more speed and less pedaling on my SE Ripper makes the bike a lot faster

Hi Dave, thanks so much for the great review! We’re glad the 13T sprocket is helping your SE Ripper pick up speed with less pedaling. Enjoy the ride, and we hope to see you again!
