Melvin tensioned with fixed cog?
 

Can you use this with a fixed cog? That'd be great, say yes.

Nope, sorry.

Is there no way to convert a bike with vertical drop outs to fixed?

Never mind, should have checked with sheldon first.

I'd love to see someone try the floating gear. I think you should give it a whirl and tell us what you think.

use the magic gear calculator.

I used to ride an eccentric ENO hub on a vertical drop frame before I bought a track frame. It was very solid and you can really stump on that stuff. ... But ENO hub cost a lot and I had it built at LBS which cost me a great deal more. You might as well go buy a new frame. (or blaze on a pair of track drop-outs? Never done that.)

... I am real stupid. I got rid of that wheel set! Someone's really having a lot of fun with it now. I ought to have kept it!

not a good idea.

why not exactly? It's not that I don't believe you, after all there must be a reason I've never seen it done, but what exactly is the problem with it?

What is the floating gear?

Try it and run 2 brakes. What's the worst that could happen?

Oh crap, I forgot what I am supposed to answer. Floating gear is this right? Sorry about that.

So wait, why is the floaty gear a bad idea then?

by floaty gear do you mean ghost cog?

I found it. Here.

There is a post there to the article which tells you the problems. But I think I will do that to my next bike if it is a single speeder. I love looking geeky.
