I tried this few years ago on another frame.
Coming from a second hand Cannondale, I was convinced it was the only good fork in the world.
The components to put a lefty on a non Cannondale frame were a bit ugly.
You can't maintain a Lefty yourself, unless you invest in very specific and expensive tools.
Make it maintained by a specialist you may find around you is also very expensive.
And you can't temporarily replace your front wheel easily if you break it on a trip or a race.
I then moved to a SID 100mm on that frame.
And now I'm very happy of the SID Ultimate 120mm on my FM936.
