Cannondale Carbon Lefty Fork

The OPI steerer fits Headshok 1.56" bearings.

There is no 1.5" steerer :) There is only a 1.56" steerer that tapers down to 1.5" beyond the bearing surfaces and accepts 1.5" stems. It's called the SuperMax 2.0 steerer. It was used across the range when they realised the OPI steerer was jokes.

Oliver seems to use the Lefty 50 hub, which is the plain old Lefty hub that all forks used back in the day, non?

Yes - this is explained above, the hubs can be found.

so it is the easiest version to find..

If you want very old 26" MTB wheels or 650b Road (Oliver) wheels, yes, but if say you wanted to fit a modern 27.5" MTB wheel like Mavic XA, you simply couldn't.

Of course - if you can get the hub you can build your own wheels. Might be a bit of a short lived and or pointless exercise for most because you are sinking money in to a dead standard and if the fork croaks the wheel is pretty much useless unless re-laced to a new hub.

Is the hub available too? @William. suggests his dad didnt like the front wheel faff - where is that wheel/hub at?

I'm still keen by the way - throwing money into dead standards and hoping for the best is a hobby.

I would just build my own frame around the fork :)

Inb4 'its not a fork' (please do this though that would be 10/10)

I'd pay money for a Slate-a-like that actually handles well. With mudguard mounts.

Mudguards on a lefty? Might struggle. Maybe if there was something to fix the right-hand stay to...

It wouldn't be that hard. I'd prefer a second stay on the front/left, but you could do this:

Heh...that’s the weird solo headshok thing, it’s a Lefty but it’s not like most other Lefties...

Cannondales development team must be smoking something proper strong

I was looking at that and thinking - what the hell is going on in that photo...

Yeah it's basically a Fatty but with one leg.

Utterly pointless - unless you really value teh aeros
