I have had an XTP2 doble disc for 11 months and so far no cracks. I wasnt expecting the frame to last me so much, my last XTP (not dual disk) lasted me 8 months, however, it cracked at the downtube where it had a huge dent. I am pretty smooth, but I also do a lot of hooks and big moves that stress the bike. I have also ridden the bike a lot, remember, depending on the amount and quality of your everyday ridding is how much it will last. Geometry is another important issue. I have owned a Hydroxx before the XTP2. When i got the XTP I couldnt get a smile off my face...So easy to control, so precise on the backwheel, amazing. I even had the hydroxx at the same time, but it was so good to ride the XTP that I abandoned it...Hydroxx´s and other bikes like the ECHO have low(er) bb´s, which in my opinion, are not so good for natural. The bottom of your bike will be hitting and getting stuck in many natural ridding situation. That is the reason why Monty´s and the new SKy´s have such high BBs. They are ment for comp and natural terrain. Hope this helps....
