Reserve's 25 650b Industry Nine Wheelset takes on gravel with an innovative and versatile layup. It's designed specifically for gravel bikes and delivers cushioning over the roughest surfaces. The Reserve 25 supports a 40-55mm 650b tire, which delivers more traction and grip than a 700c wheel. The hookless design and J-bend spokes with external nipples make it an ideal wheelset for long tours when trailside maintenance is bound to happen.
