The Industry Nine 1/1 Enduro V5 29in Boost Wheelset uses Hollow Bead Wall rim construction to add impact strength and resist pinch flats on rough, high-speed terrain. A 32-hole Sapim Race steel spoke build keeps the wheelset serviceable over years of hard riding, and the 30 millimeter internal width matches 2. 3 to 2. 8-inch tires for a stable, predictable profile. What Our Gearhead(R) Experts Are Saying:"Dropping into a rock garden at speed on matched 29s, the front and rear track the same line through every hit. Neither wheel feels like it's working harder than the other to hold its shape."
