RollerBoys, the 12x12T Ceramic derailleur jockey wheels. Crafted from a high-performance composite material by EMS Swiss, they feature a 40% glass-fibre blend. This makes our RollerBoys durable and efficient. Our ceramic pulley wheels have sealed bearings, lubricated with ceramic oil for lower resistance and protected by an aluminium cover. This ensures optimal long-term performance. RollerBoys seamlessly integrate with 12-speed SRAM road groupsets, ensuring a smooth and precise cycling experience.
