And yes this should be in RSU but ill do mybest to help anyways. I assume your riding the stock sun saddle, correct? If thst true then a KH seat is clearly in order. For long distances and comforability i would say the KH gell Saddle or a custom made air saddle would be your best bet. For a gel saddle check out UDC. This is probably the best way to get unicycles and components in the US. For instructions on how to make a custone air saddle do a search on the forums for “Air Saddle” and that should turn out some good results for you.
Its great that you have a club at your school, and are getting more people into unicycling, i have local city club, we are all going to ride downtown in about 3 more days, then the day after that we are giving uni lessons to a newcomer =p
For a better seat, the sun saddle sucks! i used it for about 2 years for just basic commuting, somehow i got used to it and don’t get sore onto it, but now switching to a KH style saddle, it feels like riding on heaven. Just look for air saddles, gel saddles, maybe cut some foam down and making a channel in the seat, also tilt your seat back a little so your sitting on the hard parts of your behind where you should be sitting at, and not the soft stuff.
Search around a lot, you’ll find great guides how to modify your seat.
