Lefty fork on a Cannondale Topstone?

[RoadToad84]

I fell in love with the Slate when it came out, but needed a bike with frame mounts at the time so settled for a Topstone (aluminium). I've since put 13,000 miles on it, and still love it, but can't get the oddball forks out of my head.

Bit of a numpty when it comes to owt mechanical, so what hurdles can I expect to face with fitting a lefty fork? Would the bars and wheel be compatible, or do I need to change the whole front end?

Thanks for that!

I'll just put a poster of a Slate on the shed wall or something instead!
