Full Speed Ahead Megatooth E-Bike Sprocket

This sprocket is compatible with 9, 10, and 11-speed chains, as well as SRAM 12-speed Eagle systems. It uses a standard 104mm 4-bolt mounting pattern, so ensure your current crankset matches this specification before purchasing.

Electric mountain bikes generate significantly higher torque than traditional bikes, which can wear down lighter aluminum rings quickly. The steel construction provides the durability needed to handle that extra power without premature wear.

The thick-thin tooth profile is designed to lock the chain securely in place. This maximizes engagement with the chain links, which significantly reduces the risk of the chain dropping during aggressive riding or on rough terrain.

The long tooth profile is primarily engineered for chain retention rather than shifting speed. While it keeps the chain secure on the ring, it is a single-speed style ring, meaning it is not designed to support front derailleur shifting.

Yes, it will physically mount to any 104mm 4-bolt crankset. However, it is heavier than standard aluminum rings, so it is best suited for riders who prioritize extreme durability over weight savings.
