Its 32mm internal channel supports modern 25–45mm road tires and is tubeless-ready for lower pressures and improved grip. Available in four weight tiers, the rim is adaptable to riders prioritizing lightweight climbing performance or long-distance durability.\u003c\/p\u003e\n\u003ch2\u003eBola 700C 50mm Asymmetric Wide Carbon Road Rim - Designed for road racing, endurance, and custom wheelbuilding\u003c\/h2\u003e\n\u003cp\u003eThe wider internal width widens the tire footprint and can improve ride comfort, traction, and stability at lower pressures compared with narrower rim beds.
