dual speed?

[mandown]

has anyone here try running a spring-loadedtensioner on the back and two rings in the front? i am considering doing this. i have a vertical-dropout HT i want to convert. i think one of these two devices could do the trick.

Haven't tried it, but I'll admit it's crossed my mind. It's madness. Madness, I tell you.

yeah, they would need a new forum for dual speeders.

Those could work, but it would depend on the difference between the two rigns you run. Those don't look like they would take up a lot of chain slack.

Have you converted the bike to a single speed yet?

I've seen that work using an old derailer for a tensioner

Dual speed? Why not use a rod system:

You'd only go 60 years backwards...

haven't done this mod yet. still looking into it. i might check into the rod system too. that seems like a great idea.

i did this with a 34-36-38 and a singulator.

i justy shifted it by hand. don't know if a f der would work
