The Big Boyd is the widest rim in the Odyssey lineup, developed with Boyd Hilder for pro-level street and park riding. At 40mm wide it handles today's larger tyre sizes with ease, while extra-thick outer walls and bead hook shaping keep things solid when you're putting it through the wringer. The low 17mm profile keeps the brake track minimal and angled so it's not catching on every ledge and rail you slide across. Directional crossover spoke lacing adds lateral stiffness, and internally reinforced spoke nipple seats and a fully welded joint keep everything tight long-term. Strong, light, and built to last.
