calling all gents -- add'l note

I just wanted to add to harper’s comments and my response that I use an
air seat (modified Miyata) on my Coker, and that makes a huge difference.
There ARE problems with modified Miyata air seats, tho, and soon I’ll be
switching to what my brother uses on HIS Coker, a modified Semcycle seat
– even better for really long rides (and he’d know, having gone on that
European ride).

Could you give some details?

Thanks,

My Coker is outfitted with the modified Miyata seat. Formerly I had a
Roach cover (it tore); now I have a new vinyl seat (all purchased from
unicycle.com). The new seat is one I put on myself, and the inner tube is
a little off, so it’s not as comfy as it could be. But even when the
Roach seat (put together by John Drummond) was perfectly set up, it
didn’t match the comfort of my brother’s modified Semcycle air seat. When
I rode 80 miles in one day, I borrowed John’s Coker, and the difference
was small but important for such a long ride. My brother actually hates
the Miyata air seat, no matter what air pressure I set it to (and they
don’t need much!).

His Sem air seat feels wider and tends not to scrunch down in the center.
He said that my Miyata air seat made it feel like his nuts were in a vice.
That is not how I felt, but I can vouch for the improved feeling of his
seat. Basically I guess it’s like the difference in two identical water
beds where one has a loose sheet and the other has a tighter sheet; the
tighter seat doesn’t squish as much where the pressure is applied. Keep in
mind that the Sem seat is covered with a fairly thick piece of material,
while a Roach voer (or the vinyl replacement) is fairly thin and pliable.

Along these lines, I think the Sem seat is a little wider in the center.
On the Miyata, the tube may be dripping over the sides a bit, or the
narrowness may just be concentrating too much weight there.

This goes along with individual anatomical differences from person to
person, which makes some seats comfortable to one group, while another
group may find the same seats to be torture devices.
