I’ve not ridden Fox forks but was looking for a bargain 140mm fork when building up my most recent hardtail. Ended up torn between a second hand 3017 Pike RC, new (but removed from a fully built bike) Fox 34 performance and a similar 36 in the basic spec. From what I’ve read all would be good forks and I went for the cheapest in the end – plus the steerer on the 36 was very tight on the cut length.
I’d go with whichever is the best deal – and if you work on forks yourself whichever you are most comfortable with.
I went with the Pike and the first thing I did was do a lowers service and stick in a 2019 debonair air shaft. So far I can’t fault the fork at all – feels nice and plush / sensitive, I’m using most of the travel and not bottoming out.
