Hi I just recived my 415 chain from bgf and it looks way to big for my rear derailer and seven sprocket cartridge? Will a 415 chain fit standard rear derailers / derailer sprockets?
Howdy 5446. The 415 is to big. It's for the engine drive sprockets. For bicycle chain, cheaper to go to local vendor or buy a junker for parts is a great way to go.
As Dan said the 415 chain is intended for the engine drive sprocket side; much like on a motorcycle. Standard bicycle chain that fits your derailer will suffice.
The only way to use your bike as you describe is to use a Shifter Kit., Other wise you will mount a sprocket on the opposite side of the wheel to use the drive on the motor and the 415 chain.
