So I have a moby 40t frame that I plan to use, but I really cant think of a good seat option for the rigid frame. I want to move the seat back at least 6'' preferably. I've seen people just welded the seat post to the front of the seat pan or something like that, but is that strong enough?
On a rigid frame that I hope can be ridden on shitty city streets, will a seat without a spring be strong enough to not break while I'm riding it? The guy that does my welding is a pro, so I'm sure he'll make a strong weld, but I'm just concerned about its integrity after prolonged use and the possibility of falling on my back tire while going 50+.
