I’ve had a go on one too, it was a really nice bike to ride.
If your never going to use a sus fork. Plenty of options with the bike.
It would be worth factoring in a larger volume tyre and better seatpost for a little more comfort.
I only ride a rigid and it only limits me on fast decents, I can’t keep up with the boys with suspension. But it evens out over a ride. Once you’ve got used to riding rigid and start picking lines it will become more comfortable to ride.
