Since I put OZ Racing wheels on, either I am giving unintended input to the bars when riding aggressively through turns or the bike is picking up pavement imperfections which is unsettling the bike slightly. Yes, I'm using proper riding technique. It is not a serious amount, the bike just doesn't feel quite as planted as I'd like. I'd like to stop it and I think a damper would help.
As the only thing you've changed is the wheels, have you readjusted the suspension to accommodate the lighter moving mass?
I'm no suspension expert, but wouldn't it now be a little over-damped (and stiffer), causing a rougher, less-planted ride?
