I'm just a seriously hungover dude who in a moment of procrastination tried to add a little friendly helpful advice from my own experience. I stand by that advice 100%I am however a better, faster, more confident rider now so I think there is something in what @Gary says.
Folk are free to use or ignore any advice I give. Whether they also choose to BUY NEW STUFF or not isn't even relevant.
I probably shoulda known better, most folk just want to
BUY NEW STUFF !!
especially in a thread about BUYING NEW STUFF
I haven't ever owned vibrocores* and refuse to ever run carbon bars but I ride a super stiff short travel (normal) hardtails with high tyre pressures quite a lot and just don't really suffer from arm pump, P&N or numbness no matter what I ride on them. (Incl DH/derp)
*have only ridden other folks Vibrocores up and down the street or around a carpark
