Is this saddle adjustment safe? (photo)
I'm using a stock Thomson Elite seatpost until I get a seatpost with setback, per my professional fitter. In the meantime he setup my saddle like this. You can actually see in the photo that the rails go past the "STOP" line. I asked if this was safe to do, and he says yes.
I weigh 160#. I don't want to damage my custom frame if by having the saddle this far backwards will somehow put too much pressure on my seattube, possibly cracking it or something.
What do you guys think?
