So I"m kicking around a custom frameset.

If I could get one built with a 1.5 headtube, and the right HT length will the lefty work with any 1.5 headset OR, is this a case where it's not only the 1.5 headtube, but having cannondale proprietary headset/bearings/cups?

I know there are some adapters out there for running a lefty on a 1 1/8 headtube, but I'm looking into seeing if there is a way to get a custom build done to just run one without an adapter.

thanks - GG

You also need to make sure your head tube length is the same as a Cannondale (Very important, as the steerer tube can not be cut!!!). I just can't think of the length off the top of my head right now. You'll also need Headshok cups and bearings/bearing seal as well as a Headshok stem because although a lefty will fit into a 1.5 head tube the actual O.D. of the lefty steerer is 1.55.

Enjoy riding one of the stiffest, lightest forks on the market!

Green Giant, I'm in the midst of doing something similar to you, building my own frame.

The Lefty/headshock will work on a 1.5" standard sized headtube, as long as it is 4.75" (121mm) long. You also need to use the Headshock/Lefty headset, as a 1.5" steerer is a slightly different size than the Cann steerer.

Good luck with your project, post her up when you're done.
