New poster here. My wife and I have a Santana Ariva. We have over 7000 miles on it in about 4 seasons of cycling now. We love our tandem, but have had 3 of the tamer trans x stoker seatposts Snap off in mid ride !!

thank god we were not going too fast.. The last time was this Saturday during the hotter than hell 100 in wichita falls texas at mile 45. We are a heafty team 400+ lbs. We are thinking of abandoning the suspension style stoker seatpost and going to a regular one. Any suggestions **********?
....by the way. We were able to; by way of a masters degree in southern construction, bind the seat to the remaining stub of a seatpost by way of 4 of my spare tubes, leaving NO spares, and were able to finish the 100 mile ride !! death before sag !!!!!!
thanks for any suggestions !!
