I was wondering if you can put a saddle that didnt come with your unicycle on yours? Like, a different brand saddle than the unicycle? Are all saddles able to be put on different kinds of unicycles? Its so hard to word this so that it makes sense, but if anyone can make sense of my badly worded question please let me know. Thanks

Makes perfect sense to me. From my limited knowledge Miyata style saddles (Miyata, Torker) fit onto an odd seatpost while Kris Holm fit onto the standard 4-bolt rectangular standard. Look at most of seats should say what kind of post they fit onto. Once you find the saddle you want you can email or call their staff with specific questions.
