Having started to do a bit of duel racing, and then discovered there's a pump track near me, I thought I'd go and have a crack to try and improve my tight/fast cornering. (i'm racing with some proper fast boys and they leave me for dead in the berms)
The place I went to had a 180° berm, maybe 8' radius to the outside of it
The thing I keep running up against is my vision:-
If I look where I natually want to look, then I end up not being able to process the information fast enough and end up backing off - especially exiting the berm.
If I look far enough ahead to process what my eyes are seeing, then I'm effectively looking over my shoulder at the berm exit as I'm entering it. Once bars and front wheel are completely out of my field of vision I get completely disorientated, as I've no feel for where the bike is in the turn and I end up backing off. I also feel like I'm constantly about to tuck the front wheel.
I know it's possible to sling the bike in and pop out at full speed (if not faster), but I'm very obviously missing something about how to, and I'm pretty convinced it's about where I'm looking.
