I’ve had one since the pre-order.
It’s not light, but it’s nice and stiff to pedal (which makes it feel light), but doesn’t beat you up either. It’s a lot nicer than some ‘nice’ steel bikes I’ve ridden and the same weight or lighter (depending on how underbuilt they were or how much Reynolds pixie dust was used).
The 35 is fine, it gets out of it’s depth on REALLY rocky prolonged rough sections. But it’s a hardtail so so does the rear end.
Not sure what the comment about the air spring relates to, mine looks like a bog standard piston in the stanchion arrangement. With the advantage that it can be adjusted without needing to buy a whole new assembly (just cut down the rubber stopper with a Stanley knife). Does seem unreasonably progressive at shorter travels though (It’s a 160mm fork), so worth taking ~10mm of the stopper off, making it 140mm, and getting a more realistic ~125mm travel.
AFAIK you can’t upgrade the damper. The Fast -UP kit never seemed to exist beyond a webpage.
Bushings were super tight to begin with but have bedded in and haven’t given me any issues.
Would I buy one aftermarket, no I’d buy a Z2. But it’s not worth the £££ to upgrade on a hardtail.
