Add a suspension seat post to the saddle, makes all the difference,
My seat post is an odd size at 34 mm, so I have to let the tires take up the bumps.
Just an FYI,.. There are seatpost adapters available that allow you to fit any seatpost into any frame,..
The Suntour NCX seatpost has a newer model with a larger diameter seatpost, at 30.9 mm. (And a larger diameter spring inside also.)
I just bought a softer spring for my NCX seatpost.
The original spring was too stiff and I wasn't getting much movement in my seatpost, even with the spring tension reduced all the way.
I'm not 100% sure that the 30.9 mm seatpost has a larger diameter spring?
I saw one advertisement where a replacement spring came with second plastic/rubber sleeve to fit over the first sleeve/spacer on the spring to take up the slack.
They may have been adding a thicker sleeve to the original spring from the 27.2 mm version to make it fit?
The 30.9 mm version may or may not have a larger diameter spring?
EDIT: I just checked
@Nvreloader 's Suntour link and it shows these options,..
@indianajo ,.. any of those seatposts will work for you with the appropriate adapter.
Finding the right adapter might be tricky with all the different stock seatpost diameters.
