Renthal Twinring Rear Sprocket 49 Tooth Silver (2240-520-49GPSI)

The Renthal Twinring Rear Sprocket combines a lightweight aluminum inner ring with a highly durable steel outer ring to deliver an effective balance of performance, strength, and service life. The inner ring is manufactured from high-strength Ultralight 7075-T6 aluminum, while the outer ring features an electroless nickel coating for enhanced durability and corrosion resistance. Finished in silver, this 49-tooth chainwheel is engineered for demanding off-road and powersports applications.
The outer ring is expanded during manufacturing and fitted over the inner ring using an interference fit. Combined with the wave-pattern design, this construction creates a permanent bond intended to remain secure throughout the life of the chainwheel. Flat socket-head screws add strength during side impacts while helping eliminate contact with the chain guide, supporting reliable operation in challenging terrain.
Self-cleaning mud grooves between each tooth help prevent dirt buildup, reduce chainwheel wear, and keep unnecessary weight to a minimum. The Renthal Twinring design is intended to last up to three times longer than a standard all-aluminum sprocket while remaining significantly lighter than an all-steel rear sprocket. With its 49-tooth configuration, lightweight construction, and durable two-piece design, the Renthal Part 2240-520-49GPSI is a dependable replacement or upgrade for riders seeking long-lasting rear sprocket performance.
