As I’ve posted with me being in lockdown I can’t say I’ve tested in all scenarios or played with the pressure in the fork but set to my weight of the sticker it is solid with no real movement on the road unless you stand up but I generally lock it out on the road. You can feel the rear has some movement but it’s pretty good on the road and you don’t notice so much. On the rough stuff it just takes the edge off everything making it such a smooth ride. I have a CX bike and you feel every bump and have to manage your position or how you ride over rougher tracks but this you just sit and pedal almost. I’m certainly looking forward to being out of covid lockdown and hitting some downhill more rutted stuff.
This is the article that sold it for me as I wanted a bike I could just ride from home and go on adventures and it is living up to the second last paragraph so far.
