    I've got a 3 speed (external cogs, not IGH) waiting for a proper derailleur right now.

    Its cool but you really don't get anything out of it...not even much weight savings.

    That looks like a half-rear end build to me... He probably could not pull the large chain ring off the crankset, so he decided to run it this way (and leave the dead shifter on the frame as well).

    If I was going to disable one derailleur, I would rather disable the front. The RD gives you a lot more flexibility on gearing/hills/etc.

    I don't get it. Seems like a exercise in futility.

    Yeah I would defiantly agree with the just using a RD. My 69 suburban was like that...

    I guess someone had to try it. Just think how much we all learned, thanks to his, or her, expression of creativity.

    I can see it working with a compact double maybe. Ten tooth difference isn't enough--ie. it is a change in gearing meant to me used in conjunction with your rear gear range as well.

    Seems like a waste of time. Again, if I was going with this, I'd probably do it the other way around (you know, like every company that made a five speed bicycle did back in the day). Another thing you could do is find a kick back hub and eliminate derailers completely. You'd have two gears, and built into a set of light alloy rims, you could probably make some serious tracks with it. Not sure about cog interchangeability though.

    Before I acquired my Sirrus, the guy that I got it from ran it as a two speed. He had a Paul's chain tensioner in lieu of a rear derailleur. I thought it was a pretty slick set up, myself... I wouldn't mind putting together a commuter with a similar setup.

    If I wanted a 2 speed, I would do a retro-direct drive... It's a lot more work, but that's part of the fun, right?

    If I were going two speed it would have to be a kickback hub...

    OK, how about an original Two Speed that I found a few weeks ago...

    Victoria made in Victoriaville, with a two speed Strumey Archer shifter and rear hub. The bike is a hoot to ride even though I do prefer vintage road bicycles.

    He's obviously using the rear derailer as a chain tensioner. He can shift to the small ring for hills. It makes the bike more versatile than a single speed.

    bt off topic but I saw a two speed bike for sale, where the rider had to get off the bike and twist a big plastic thing on the hub to change gears. Twist left for low gear and right for the high gear.

    I have yet to see another bike like it. I'm geussing the bike was built in the 1970's, and was a compact bike to fit on the back of a boat.

    I stumbled across this set up looking for stuff for my Dawes build, it's pretty cool but a bit pricey IMO. You could make a four or six speed out of it easy enough
