KH Saddle First Use

Towards the end of last year I ordered a KH Velo saddle for DW to give
me for Christmas. I fitted it to the Coker when we got home after
Christmas, then I didn't ride it. Then I didn't ride it a bit more.

The Coker usually only gets used for commuting once or twice a week, if
that. First a succession of colds meant I didn't feel like the extra
effort of yiking to work (added to which I have to get up 20 minutes
earlier to yike to work, which is really hard to do in the winter).
Later on, DW's advanced state of pregnancy meant that I might have to
get home quickly, so I wanted the extra speed afforded by a second wheel
and a decent range of gears.

But now the baby's out, I'm feeling good, it was a lovely morning, so I
did it.

The first thing to become very obvious was how much deeper the KH is
than my old Viscount. I had about 3/4" less seatpost showing than with
the Viscount and it was only just rideable. I stopped after 1/2 mile
and lowered it by about 3mm, then it was perfect. (I wasn't wearing the
same shoes that I used with the Viscount, but if anything I think the
soles on the new shoes may be slightly thicker).

The next thing I noticed was the flex in the handle. It's certainly
more comfortable to hang onto than the front of the Viscount, or the
grab rail of my DM contoured, but a little less flex would be nice.

When I dismounted, I discovered a problem that I may have to do
something about. The depth of the saddle makes it quite uncomfortable
to catch during a forward dismount. I think I'll have to fit a handle.
I stuck to rear dismounts after that, but it's important to be able to
grab the saddle during a dismount either way.

Comfort was very impressive. I usually ride a recumbent bike, but I
bent it last week so I've been riding a wedgie to work this week. My
sit-bones are sore from what I used to think of as quite a comfy saddle,
but I'm no longer used to. So I expected to feel sore sit-bones as soon
as I mounted the Coker. But instead, this was the first time that I've
yiked the 5.4 miles to work without feeling slightly sore by the end
(except perhaps for when I was using 5" cranks).

Unfortunately, the saddle also seemed to put pressure on the urethra
that I don't get with the Viscount. I had the nose angled up as far as
it would go, so I angled it down slightly from there for the ride home.
This relieved the pressure on my urethra. There seemed then to be
more pressure on my sit-bones and inner thighs, but that could well just
have been because it was the second ride of the day.

Finally, speed was better than I expected. I haven't ridden a unicycle
for 7 months (except for a bit of bouncing around on the patio to
entertain DD), so I expected a slow ride. And my cadence *did* feel
low. But I still managed a pretty average speed for my Coker commute.

All in all, I'm quite happy with this seat.

Shame that the KH Velo was unused for so long...

Mostly people report sitting more on their sitting bones if they tilt
the saddle /up/. It may sound counterintuitive. Maybe you need to make
a conscious effort to reposition yourself more to the rear? The
increased pressure on the urethra may also have to do with the general
softness and deepness of the padding. It distributes the weight but
that implies pressing everywhere.

Is it broken again? Oh well, thanks for letting me know I'm not
completely alone.

I know. I was quite surprised by the difference.

It probably is. The KH saddle could probably benefit from a cutout
section in the middle. I'm not ready to go hacking it about just yet
though ...

I would prefer that the KH saddle didn't have such a deep "U" shape.
The deep shape causes the front of the saddle to give the soft tissues
less room and is all too constricting.

On my air seats I trim the foam at the nose of the saddle to give the
saddle a shallower "U" shape. I find that shallower shape to be much
more comfortable. I have pictures of what I do in my 'Air Seat Gallery'
(http://gallery.unicyclist.com/Airseat/). Specifically 'this picture'
(http://tinyurl.com/2sjkx).

I would like it if the KH saddle had the same operation to trim down the
foam at the front of the saddle.

I agree to that the KD saddle is too ‘full’ at the front for men, it
doesn’t provide enough space to be comfortable. The softness I also find
is a problem with pressure causing lost circulation in that area
underneath. I’ve now got two KH saddles, your photos are great!

A couple of questions, did you make the pillow? From what material? Do
you find that you can ‘feel’ the inner tube in the pillow? Did you
make the pillow smaller or larger than the saddle base? How did you stop
it all from slipping around inside the Roach seat cover?

Thanks lots of questions, but you’ve got me spirited to alter my
saddle.

I made the air pillow myself. I don't know what kind of fabric it is.
I just looked for a heavy duty fabric that was on sale. Color didn't
matter because it's inside the seat.

I used the foam pad from a Miyata seat as the pattern for making the air
pillow. The carbon fiber seat base has the same shape and size as the
Miyata seat so the Miyata foam makes for the perfect pattern. To make
the pattern I traced around the Miyata foam and then added 1/2" for the
seam.

You want the air pillow to be slightly undersized for the seat base
because when you sit on it it's going to bulge out a bit. I made
several air pillows and because of my poor sewing some of them were
wider in the middle area than others. The wide ones that bulged out too
far beyond the sides of the seat base were not comfortable.

Because of the foam on top of the air pillow you do not feel the tube.
You know it's there because the seat is cushy and you can adjust the
cushyness by changing the amount of air in the tube. But you cannot
feel the folds in the tube.

The shape of the foam on top of the air pillow makes a big difference in
the comfort of the saddle. My Muni seats use the Miyata foam, but I
didn't find the Miyata foam to be comfortable on my Coker. The shape of
the Miyata foam was too blocky. For my Coker seat I'm using the foam
from an old Schwinn saddle. The old Schwinn foam is very contoured with
a shape very similar to the Viscount seat. That contoured shape was
much more comfortable for Coker style riding. I'm going to try the foam
from an old Viscount saddle to see how it compares.

Saddle comfort is more than just adding an innertube. The shape of the
saddle is also very important and the shape of the foam on top is very
important.

I do nothing to keep the air pillow and foam from sliding around.
Things do stay in place inside the Roach cover. I have no problems with
things moving around and getting out of place.
