Talk you out of it? Sorry, can’t do that. Built a Singular Swift up last year: rigid, ss, 29er. I’m irrationally attached to it. It’s what I want to ride every time I go into the garage.
Trails round here sound similar to you: lots of hills. Techie downhills in the trail centres (inners/gt) or more flowy on the natural stuff.
There are limits though. Took it down Caddon Bank at inners the other week – can’t say I enjoyed it. Rigid forks do improve your technique but there’s a point where I just want more damping than my arms & knees can give.
I’ve just bought some forks (Reba 100mm) to try out on the gnarlier stuff. Keen to see how much extra I gain downhill vs. what I sacrifice on the ups (weight/bob).
But: I still plan to run rigid on the smoother stuff. Don’t know if its the simplicity, or direct connection to trails, or mid-life crisis – but there’s something about rigid ss that just makes me smile.
