How much does it cost to manufacture an adaptor here in the US ?
I used the lefty once and really liked it and am now thinking about one for my motolite.

I see one on ebay :

If you are thinking of making your own/getting your own adaptor manufactured then it would probably not be that cheap as it would be a one off item = more expensive.

As you have found on e-bay Cannondale makes one, I would suggest contacting a Cannondale dealer and find out what the MSRP is.
The ebay item is a one off too, just wondering how much it would cost to duplicate it here in the US.
There's a guy in this thread:
http://forums.mtbr.com/showthread.php?t=104828&highlight=lefty+turner

that machines steerer tubes and clamps for 1 1/8" lefty set ups. Hope it helps.
Cannondale says..

just got an email that states they don't make an adaptor or new steerer for 1 1/8 head tubes.

Guess the ebay guys getting my buisness.

Did you make that? That's sweet! When I put my Lefty up for sale, I'm gonna include a link to this page, if you don't mind.
Thomson, the stem and seatpost folks, either just started making one, or willl be shortly.
Yes I do make those.
I don't mind a link to this page at all. Thanks for asking!

Also, I talked to the Thompson people at innerbike.
What they showed me was an adaptor that allows the use of a 1.125 stem on
a lefty fork on a cannondale frame. NOT an adapter to allow use of a lefty
on a 1.125 head tube frame. Now that is not to say they havn't decided to
make something like my clamps since innerbike. But there seemed to be
some confusion over what they had at innerbike. So I checked it out and it
wasn't what most people thaught it was. If they did decide to make one I am sure it would
be quality. They're parts are as nice as anything I have seen, and they seem like
nice people whenever I have delt with them.

Why sell?

Why would you sell your lefty? Are you going to replace it with a newer model?
Have you felt the new spv as pictured? It's awsome! And it acutally feels better
with a short stem and some real handlebars, unlike you see on most cannondales
with lefty's on them.
Jake,

Do you still have two more clamp sets left?

You're right, I got confused as to what I was looking at. Thomson doesn't make anything that will allow a LEfty on a 1 1/8 head tube.

I'm not real happy with my Lefty. I don't think it was designed, with a 210 lb rider, in mind. The adjustability isn't there, and can't find a happy medium to ride with. I put in heavier springs, and now it's to stiff, and has no low speed compliance. When I go back to the lighter spring, it's real nice at low speeds, but suck's when I start going a little faster, or God forbid, leave the ground.

Damn, that's sad to hear. I run between 205 and 240 and I love mine.
Which lefty are you riding?? You can also add some preload to a lighter
spring. I hate preload but it may work for you.

I think I have exactly 2 left. I am planning on making more
but it will be a few weeks/month since we are still in the process
of moving. The two I have left are annodized a dark grey.

Lefty 1.125" adaptor

I made some shims to fit into the existing Lefty fork triple clamps.
I first removed the Lefty steerer tube, then I turned a shim that I pressed and bonded into the lower clamp with the 1.125" steerer, then I made a shim which a slit cut into it so that when I tighten the upper clamp it would clamp onto the new steerer. I've been using this set up on my Bianchi DISS single speed for 1 1/2 years trouble free.

Keep in mind that you have very little to no adjustment for the length of the existing headtube and headset stack height
Carbon Lefty model

Have you thought about making one for a Carbon Lefty? Carbon leftys have the crowns bonded to the fork leg, you cant remove them or slide them up or down. The 1 1/8" adapter would have to have the right diameter for the steerer clamps, then step down to 1 1/8 everywhere else. Hope that makes sense. You would be quite limited as to what stack heights you could use, but holding a lefty up to my frame, I can tell it would work?

Yes, a 1.125 carbon lefty adaptor is in the works. The project is very simple until
you want to put them onto a bike with a 4.5" or taller head tube. Then (no matter
what headset you use) there is just not enough room (unless you have an internal
head tube). We have come up with a way to use them on headtubes up to 5.0" tall.
I cant talk to much about it now but it should be available in late Feb early March.
You can check our website (project321.com) for updates on that project. Or you can
e-mail me. Also, we have compiled a small list of people that want the first ones of the
machine. I can put you on that list if you like.
