Description
FSA Megatooth Direct Mount Chainring | Boost 148 | Bosch eBike Compatible, Steel, ED Black
The FSA Megatooth Direct Mount Chainring is a purpose built steel chainring designed for Boost 148 eBikes running a Bosch drive unit. Built around FSA's Megatooth narrow wide tooth profile, it keeps your chain secure under the high torque loads that eBike motors produce, making it a dependable replacement or upgrade for riders who put their drivetrain through hard use.
Built for Bosch eBike Drivetrains
eBike drivetrains place far greater stress on a chainring than a standard bike, so a durable, precisely matched part matters. This chainring is compatible with Bosch engines and uses a direct mount interface, fitting straight to the drive unit without a separate spider or crankset. It is designed specifically for Boost 148 spacing, helping maintain correct chainline for smooth, reliable shifting.
Megatooth Chain Retention
FSA's Megatooth tooth profile alternates narrow and wide teeth to match the inner and outer links of your chain. The result is improved chain retention, helping reduce the risk of dropped chains over rough trails, big hits, and sudden power delivery from the motor.
Strong Steel Construction
Made from steel for long term wear resistance, this chainring is suited to the extra load of motor assisted riding. The ED black finish gives a clean, understated look that suits modern eMTB builds.
