oh my god! this is the BEST bike I have ever had! Even better than the proto. Its VERY stiff, the box section tubing and long weld between stays makes the back end very rigid, the front is also very stiff from the tubing profiles. Strength also seems very good. My proto was put through its paces, missed taps to downtube, missed sidehops to chainstays, hooks, harsh taps, big drops. Not a single dent or crack (but plenty of scratches). The geo is slightly different, mainly the longer chainstays. I have been wanting to try out a higher bb bike with longer stays for a while. You get the advantage of the clearance you get with a higher bb, but not the pogostick effect you get. I have found the longer stays helps loads with taps as it keeps my weight forward when landing and stops my back wheel looping out when my front hits the wall. I did a 57" (almost vert) tap that I have been trying for years on my first ride on this stinger! Sidehops also seem good, I am not sure the exact reason, but I managed to sidehop a rock at my local place that I have not been able to do since I broke my ankle. I am loving the vees also, best brakes ever, and yes, one of my levers is drilled out loads lol, it was on my racing bmx (7.8kg bmx!) Videos and pics to come soon hopefully (when the weather gets remotely good!)
