Looking for opinions from those that have put a suspension seat post on a ride1up 700 series bike? What suspension seat p[ost did you go with, and why? What size was the suspension seat post? And did you notice any improvement in the ride using the existing seat that comes with the ride1up 700? I'm looking to improve the comfort on my ride1up, but wanted to take this one step at a time. Any thoughts and opinions would be appreciated.
