Emaxx Transmission?

[Serum]

Yes, you could add the gmaxx singlespeed conversion, which takes away all the unneeded parts.

It's a bit pricey though, but a nice solution if you can swing it.

A more affordable option would be to use the drivedog/coupler from that gmaxx conversion. I don't know if Mike still has them, but he used to have them for about 15 bucks or so.

Another option would be to put two M3 screws through the drivedog and the gear itself. If you use self clamping locknuts it can be pretty strong too.
