Bombshell ONE80 wheel set is first in our new wheel sets line. 5 years after the first, original SLX wheelset, which has triple POI ( points of engagement ) at that time, ONE80's comes with almost twice as many POI, moving the standard to the next level. Stiffer over sized axle with 8mm bolt and ONE80 clicks newly redesigned driver providing incredible acceleration wherever needed. Higher flange on drive side is reducing spoke length and adding required responsiveness to each of your pedal strokes. For those who know what they want.
