versatility cable system

Versatility. From a clean singlespeed into a geared bike. I came up with this,but would be interested (and not too surprised) to know if it has been done before. | Flickr - Photo Sharing!
I don't know if this has been done before, I was pretty proud when I came up with it.
thoughts?

Not exactly sure how the cable stop or lever boss will be attached to the frame. But if they only bolt down against the frame with a simple water bottle like boss (and not a classic lever boss with a square base) I would worry about the stops or lever starting to rotate on the frame from the forces. Do you have an installed photo so I can have a better understanding? Andy.

I'm not sure I understand the question. Are you taking a single speed bike and putting a crank set on it? I'm with Andy on what he was wondering abut also. If "yes" to the first question its been done before.

Been there, done that, and seen many variations of the theme.

I like simply using removable modular housing guides on bottle bosses.

it uses a slightly deeper bottle boss.It doesn't rotate due to the curvature of the adapter. the shimano downtube attachment is available curved or flat.so that's not going anywhere.
It's for frames I already have in stock, so a shop can limit their stock and offer several options. & hopefully I can move some of them.
plus I never liked singlespeed convertions on old frames with the lever bosses sticking out.

Curt Goodrich built a Rivendell frame that had a removable left-side shifter boss because the customer was mostly going to run the bike with one chainring. I can't find any pictures of it, unfortunately.

thanks I was sure it wasn't new. I probably saw something similar somewhere, forgot about it then imagined I't come up with it when I remembered.
