IMO if you're expecting to break #25 chain you are doing something wrong

Aside from the fact that even with 3 chains at least one wheel will always be powered if one chain breaks (I can attest to this having happened ).

Most of the off-the-shelf gearboxes (with the exception of the AM SS) require a second reduction after the gearbox, especially with 6" wheels. A second reduction will also allow you to "tune" your speed.

Just my 100 sense.
