You can't avoid or predict every bad spot in the road, especially if it's new territory. When that happens, hang on! You will come out of the seat. You just have to be willing to take the good with the bad and the only bad is the ass jarring you'll get from time to time. They may be few and far between, but like someone already mentioned, "FUCK, THAT HURT". I plan to have some seat improvements at some point and time but until then, I'm loving it!
