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!

Good point, it's 212 mm. (kinda helpful information) =

Bystickel does HeadshockLefty frames

and Steve's work is as nice as they come.

Here is link to my bike when he first built it:

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.
