I’ve owned several over the years..
Lefty DLR, carbon ELO, Max 140, another DLR, and probably a couple more.
I am a bit of a cannondaleophile though.
(oh and I also had a USE SUB for a short time….)
They look great, have limited hub choice, need an adapter to true and build the wheels, cant use roofbars easily, or get them in the back of small hatchbacks..need specialist tools to get into, and are a pain to service the bearings…
servicing the damper though is easy as it comes (once you have the right tools to get it out) and they ride really nicely. different, but nice.
They’re odd feeling if you’re used to normal forks. kinda like changing from rockshox to fox. Feel similar, but do the same job slightly differently.
Leftys are stiffer than most and you notice. I suppose now there are an increasing number of 34mm+ stanctioned forks out there it’ll be less noticable, but for the weight, they are great forks.
