I'm slow to respond here. So, I'm someone who cut their hand on snapping QRs (twice, nasty gashes) but this was before I worked out that a little oil on the QR fixes the problem. No issues for a year now! I tend to agree that the front end is a bit twitchy. I've had one bad spill on a rough surface - front wheel disappeared under
me and I was off. Is it a problem? Well, all bikes have compromises and any smart rider finds out what they are and works with them. Regarding the harsh ride: I disagree, but that probably has more to do with set up and the amount of weight was pushed onto the bars. I have a Thudbuster with is magnificent and doesn't take power away like most suspension.

I ride mine every day in London (regretably no longer Chicago) and love the speed and ride.
