Yea, when I saw that shot, and how much my rear tire is compressing, I wondered how I managed to make it through the ride without a pinch flat, as there are a lot of these log/water bars on that trail.
And the strange thing is, this bike which is much lighter than my AM ride and has much more "XC-ish" rims has been fine all these years, while my AM ride with Easton Havoc rims, I managed to ding a rim already.
Granted I ride the AM bike as if it were a mini-DH bike at times and tend to ride a bit more "spirited" on my AM ride bouncing off of things rather than going for smoother lines.
