Can anyone tell me how they would rate the solo seat by low & mean on comfort.

I think I've used almost every seat on this bike, its like everything else your results will vary. Personally I think the lm seat pan covered in memory foam with the right contour is perfect. I always take breaks atleast every two hours because I enjoy the break.

all other seats are way too high up for my style and I just don't care for any bike where I feel I'm riding on top of the bike.
