Flyer Cassette Sram Dual Drive 8-speed – For Ebike

The SRAM PG-850 cassette is compatible for all 8-speed derailleurs and for SRAM DualDrive 3×8-speed systems. It has 11 teeth on the smallest and 32 teeth on the largest sprocket.

It is compatible for all Flyer electric bikes with the 8-speed SRAM DualDrive hub gears (combined hub & derailleur).

The cassette is characterized by the high-quality polished surface against dirt adhesion and good durability.

Mounting Tip:

For assembly, we recommend special sprocket tools. These are also called sprocket pickup and chain whip.

The sprocket remover is placed on the lock ring to loosen it, thanks to the guide pin, slipping of the tool is almost impossible. The chain whip is placed around the mounted sprocket for counter-holding and fixes the freewheel, so that the sprocket can be easily disassembled.
