Bomb-proof durability meets versatile gravel and cyclo-cross performance with the DT Swiss RR 521 DB.
This 32 mm deep, 20 mm wide modern road rim bridges the gap between endurance road and adventure riding—perfect for drop bars and wider 28-35c rubber.
Built with Strength Boost Welding Technology for a flawlessly welded joint, the RR 521 delivers exceptional stiffness and strength. Equipped with DT Swiss Squorx ProHead nipples and PHR washers, it maximises rigidity without added weight. The tough black coating resists the rigours of rough terrain and road miles alike.
Compatible with clinchers or tubeless setups using DT Swiss tape and valves. Presta drilling, 24 mm outer width, 581 mm ERD, and a 130 kg maximum system weight make this rim ideal for heavier riders or loaded adventures. At just 520 grams, it's a serious performer for cyclists seeking durability without compromise.
