Can’t knock King although I wouldn’t buy one now, way too expensive.
I bought my rear for £240 new on offer about four years ago, from Stiff.
I also got the expensive tool eventually.
When I wanted to bolt my axel up, King did the parts (fun bolts), easy change
When I almost bought a frame that was 142mm x12mm thru axel, King did the parts, ok they were £80 but at least I could have still used my hub! I like the way it can grow with bike design changes, so far anyway.
I’ve “serviced” it once. It didn’t need it, once the inside was open, it was mint, after 3 years and 2 Alp trips.
The engagement is nice and swift, the noise is nice, although louder would be better.
I posted on here that I liked the hub but the RRP (then about £340) it wasn’t worth it. I still feel that way. If you find a reduced one, maybe it’s worth it.
As far as the engineering goes, I can’t fault it.
