Rode down to Swanson for TNR, didn't even finish first lap when sitting through a g-out, this happened. With the fix, I sit more, especially when the cadence is high. With all the punishment this took in the rocks out in CO/UT, I can understand the accumulated stress causing this. Will probably go with a Thompson setback - less leverage/stress on their design. Was able to readjust the seat and ride home.
