Great tip, thanks for sharing - I just set my new "seat height stopper" in 2 minutes with single wrap of Gorilla tape, and no patience or trial & error needed. Just measure the difference between your preferred seat height, and the seat tube at full extension, and rip the tape to this difference. Then place the tape right at the very bottom of the seat tube where it flares out (this is the OEM stopper). So if your first measurement is 1", for example, then a 1" piece of tape will act as the new stopper, just 1" earlier.
