I remember it being the best climbing bike I had owned, better than a very traditional 4″ hardtail I’d owned previously and (perhaps not surprisingly) better than the 5.5″ travel ‘hardcore’ hardtail I owned after that.
Also great fun on descents, singletrack etc. Only got rid as I was moving somewhere with almost exclusively steep rocky rooty descents and fireroad climbs.
Can’t remember how stiff it felt, the previous bikes were both also relatively stiff. The big seatpost and ‘tight’ rear stays would maybe suggest it’s relatively stiff for a hardtail, I would have gone tubeless and stuck a Ti post on there eventually if I’d kept it.
