    Ever

    I'll write a review tomorrow once I've put a few more kms into it.

    what do you do for foam? and how much?

      ooooooh interesting, it is about time we got a choice in curvature without having to over pad the center of the saddle and cause more problems.

      I would like something a little narrower as well

        Nice!

        70g for that carbon you say (on FB)? Is that right? That's much less than the normal CF bases which are something like 260g.

        You could also trim the plastic rear bumper down to save a good 20g (dead easy with a hacksaw). I've had a bumper like this for years now and it does as good a job keeping scrapes off the carbon base.

        There is a reason why uni saddles are heavier than bike ones (though they could still be closer) - they require a lot more structural strength for pulling on the handle on the front.

          I used an old KH freeride foam (cut in half previously). The hardware (plates) was from a broken KH seat. I need to trim off some foam from the front. The seat base is almost completely flat, but the metal plate at the front and a little too much foam makes it stick up a bit.

          Not absolutely sure. I used kitchen scales which aren't the most accurate. But it is at least half the weight of the gemcrest bases. The gemcrest ones are made for trials and street, which makes them virtually indestructable, but you don't need that for road.

          Put it this way, the combined weight of my mountainbike handlebar (118g), stem (140g), seat (250g) is two thirds the weight of the KH Slim saddle. The handlebars are Titecs, WTB stem and an old Ti/kevlar seat.

          The combined weight of my road bike handlebar (230g), stem 105g), seat (195g). I use Deda Newtons, Alpha Q prolite stem, and a San Marco seat. Add in bar tape and it is still comfortably lighter than a unicycle seat.

            Since the carbin seat bases are made by hand, what would it take to have a couple different curvatures, say one that's flat like your, one that is semi flat, and one that has the KH curvature.

            I don't know that I'd want a totally flat seat for muni, but I'd certainly like to tr on that has half as much curvature as the Gemcrest or KH.

            Did you lay up the seat your self?

              It's easier to add curvature by carving the foam, than getting rid of curvature by filling in the curve with foam (as done with KH bases).

              The bases were made by a friend, I contributed to some of the materials. The mold I think was the most time-consuming task.

                Indeed - not at all straightforward to make different moulds.

                Like Feisty I'm hoping it's narrower than a standard base (and that us normal mortals might be able to get hold of one).

                  It is narrower than an unmodified KH seat, because normally the foam has a lip around it that sits over the base. With this seat, I used foam from an old shaved seat, but the top bit, without the lip, so it's narrower. I taped some inner tube rubber on the sharp carbon edge so it doesn't cut into the seat cover.

                  We're calling it the "Flatfish NNC". I'll write a proper review on Adventure Unicyclist once I put a couple of hundred kms on it.

                  First proper ride on the seat today, it was amazing. I was expecting to fall off the front as there is no curve to wedge against your crotch, but that was not the case. All I felt was greater freedom of movement, better control, and no wedgie sensation. It supports the ischial tuberosities, which is exactly what you want.

                  I did my 32km training route today, with just regular shorts (I wanted to try it with no padding), and a standard 24"/125mm unicycle (high revs, low resistance), and I have no crotch soreness whatsoever.

                  I'm so happy

                        Hmmm, I'm usually good with words, but ichthyal tuberosities would be fish and potatoes, right?

                              I'm not sure I can convince my friend Pete to make huge amounts- they take a lot of time and effort. All I did was contribute some of the materials.

                              The idea of this seat is basically to test my theory that flat seats are better. Now I'm convinced.

                              The fact it is made of Carbon Fibre is a bonus, but I wasn't after a carbon seat (I already have three), I was after a flat seat. If I hadn't come across this, I was going to cut one out of metal. The seat pattern is more or less a KH Seat that has been flattened, so all you need is a flat one dimensional KH seat pattern that you can machine out from a flat sheet of, say aluminium.

                              The lip around the edges is probably not necessary (you can always use more foam if you want a thicker seat), but adds stiffness. Either weld it on, and/or use a reinforcement plate for stiffness. The most important bit to reinforce is the front end with the handle. You could even cut it out of plastic or wood, as long as you strengthen the front end.

                              The KH reinforcement plate (even though it's curved) might work by drilling extra holes and cutting off the bent bit (because by flattening the seat, the distance between the seat plate and handle is less). I'm thinking of installing it when I use a KH T-bar, just for added strength.

                              It's the bony bits of the pelvis that you sit on. But given the fact that I paid $60,000 to go through medical school, I refuse to call it the 'sit bones' like everyone else seems to.
