Wheelbuilding tips with Lefty hub
I have to build a wheel for a customer with a Lefty hub.
Are there some way to build it in my ordinary truing stand or have I to build it in the single leg fork.
The second question I have is how to center the rim. Should I center it between the flanges or the axle.
Regards

If it's not a disc brake hub, I would assume it should be centered between the flanges. I have no experience with these, so that's just a guess. If it does have a disc brake hub, I would call Cannondale and ask.

Yes it's a disc brake hub.
I think the easiest way to center the rim is in the fork and center it against the fork head.

There is a specific tool that you can get so you'll be able to mount it in your truing stand. You'll just center the rim up between the flanges.

from cannondale you get a hub insert that sets into the lefty hub and makes it a regular qr for truing/dishing/building only, you can not ride on this adaptor. just call cannondale.

I have tried to get the tool for putting a lefty in a truing stand for nearly a year. Cannondale refuse to sell me one. Maybe if you have a freind in a Cdale shop you can get one. I ended up making a set of spacers to fit in the bearings with spacer between to prevent binding. looks very ghetto, holds the hub fine.

Thank you for the answers. It look like I have to build it in the fork anyway.
I'm thinking of setting an anchor nut in the bottom of the fork head tube (sorry for my english. I hope you understand me) and use a threaded axle to help me to center the rim.

P.S. Your English is better than many Americans.
P.P.S. I just realized that there's no such thing as a rim-brake Lefty fork. Dufus!

Right there is a Lefty truing adapter that any Cannondale dealer should be able to get you. I got one a couple of months ago for $17 through my LBS. Retail is like $20.
