Paradigm - Shimano 105 7150 (Di2)

Experience the advantage of our all-new Paradigm Oversize Systems — engineered to outperform every other oversize pulley system on the market in durability, efficiency, and real-world performance. Utilizing an optimized 14-Tooth / 20-Tooth pulley wheel combination, the Paradigm Oversize Systems are built to reduce drivetrain friction without sacrificing what matters most: durability, shifting precision, or premium aesthetics. Unlike competing systems that rely on nylon plastic “composite” cages and pulley wheels, Paradigm Oversize Systems feature cages and pulley wheels made from genuine 100% carbon fiber, delivering superior stiffness, strength, and a true high-end finish. Paired with our unique coated ceramic bearings, each system is designed to provide smoother operation, increased efficiency, and long-lasting performance ride after ride. Whether you are upgrading a stock drivetrain or replacing a competing oversize system, Paradigm Oversize Systems deliver a noticeable improvement in both performance and quality.
