    At the moment, my preference is to have a single frame and adjust the foam shape (e.g. Slim, Street, Freeride) to consider a spectrum of rider preferences, plus offer the T-bar to re-distribute weight further back. Not everyone wants a narrower waisted saddle, either, so I have to come up with something that hits the "sweet spot" in terms of what works for most people most of the time.

    Injection molds are expensive considering the number of saddles that can be sold in a year - more than US$40,000 all told (mold tooling + design drafting, but not my time) went into development of the Fusion saddle frame and bumpers. Of course, having multiple molds would be great but all told I've been pretty happy with how it turned out - certainly an improvement over the previous saddle frame.

      Interesting. I've got 125 QuAx cranks on my road 29er (Ventures on the muni and 19er). I have to admit I've not noticed the difference in terms of knee comfort or anything else like that - in fact I'd not have realised at all if you hadn't mentioned it. Shall have to get a ruler out and measure what the difference is. Though now I think about it, I do actually have less issues with saddle comfort on the 29er, which given one of the reasons for discomfort on the muni is the saddle feeling too wide and putting pressure on the inside of my thighs, I have to wonder if a wider stance might help with that. Then again the difference is at least as likely to be due to the shorter cranks.

      I think I had been veering towards putting on a disk brake using Spirit cranks anyway - Kris's comments above pretty much confirms to me that there's unlikely to be any significant downsides (I'm used to wrenching disk brakes on a bike, so not expecting to have the spacing issues some are having). That does also give me the option of only having to buy a D-Brake and the cranks to make the upgrade on my current muni, as I even have a spare brake I could use for now.

      Given I also often catch my right ankle on my 19er (I have a very enlarged ankle bone due to a chronic ankle injury) maybe I should also bit the bullet and get some different cranks for that...

        So after riding some muni on someone's KH29 the other day, I decided to get the KH29. I don't want to wait until November, and I am a bit hesitant to get the first iteration of a uni design.

        I am going to get the crank-mounted discs.

        The KH29 I rode on was a bit high for me. My seat post was a bit long and I couldn't get it low enough for me. Probably only 1/2 inch too high, but enough to be noticeable. I was on trails that were mostly rolling, but with some rooted and rocky steep uphills. Nothing super technical. I did pretty well. Though I had trouble on the steep sections keeping my wheel moving. Mind you, I have never ridden anything bigger than a 26 before.

        I was on 150mm cranks. I am 5'7" and am now trying to decide between the dual-hole 165s vs the standard dual hole 150s. the guys I rode with said they sometimes have trouble with the 165s being that it hinders their rolling up the hills, but Josh from UDC recommends 165s. I know it comes to preference, but I have not ridden with both, so I don't know which to get, and the Spirit cranks are expensive. Advice please...

          If you're planning to ride mostly road, with some xc/light muni, go with the shorter cranks. If you'll ride mostly trails and want to push into harder trails, go with the longer ones.

          Personally I now only use my 29er on trails, and use 165's. But 125 was good for riding the 29er on road and paved bike paths.

          Edit: I note I'm 6'4" so maybe that affects my preference, but the leverage factor is the same regardless of the length of your legs. 165 is still shorter than most bike cranks.

            Mostly commuting on the street, with muni on some challenging trails a couple times a month.

            So really both types of riding. I can't afford two sets of cranks, and prefer the dual hole.

            The choices are:
            127/150
            or
            137/165

            If I get the 150s, I would ride most of the time on the 127s and use 150 for muni. I've heard that if you are shorter (I am 5'7"), the shorter cranks may actually be better.

              With the commuting, the shorter cranks are probably better for you. If you'll be switching holes that often, you might also consider a quick release seat clamp.

              150's on trails are fine, and preferred by many over longer cranks.

              Ultimately you'll end up with a 36er for your commute.

                Oh god more choices. If you had to choose 3 unis what size would you get for trials muni and commuting? 19, 26 36? Would a 29 be in the mix?

                  Trials is easy, 19. That's the point it stops being easy - I currently have a 26er for muni, but very tempted to try a 29er (I have a 29er for use on road, so it's only a case of swapping the tyre, swapping the cranks and lowering the seat - don't know why I haven't done so already ) Of course some people will suggest you actually want a 24er for muni - and doubtless that would be the preferable size on some trails. Then again some people ride muni on a 36er...

                  As for commuting, well most seem to prefer a 36er when they get good enough, but it does depend on your route - my standard transportation route from the village I live in into the local town is twisty and tight enough that I'm not sure I'd ever be happy riding a 36er on it. What I really want for that is a 29er guni!

                    Yes this is the point where a gunk looks good. I don't want 4 unis. Then again the appeal of a uni is simplicity and a custom made geared hub is probably complex. What if it breaks etc.

                      The ones you end up riding are the ones you should keep.

                      I sold my Trials, it was never ridden all that much.

                      I sold my 24's when I spent all my time on a 26".

                      I sold my 26" when I spent all my time on a 29".

                      I now split my time between 36, 29, 32, with an occassional foray on the Oregon 26 (soon to 29 x 3).

                      Some people keep all the unis they buy, other folks have a limited budget and have to buy one to sell one.

                      When I was still riding 26", I didn't foresee myself going to a 29" because it was too big for muni, but now I ride a 29" a lot and I consider it small in contrast to my 36er.

                      A guni, well, that's a totally different beast all together. Not for me, at least not right now, though the force is strong in this one. Gunis just don't work in the same conceptual framework as a bicycle, so just becsuse we are all familiar with bike gearing, we assume we know unicycle gearing, but they are no more the same than veggie burgers and beef burgers. Gunis work, but not like you think. Try one before buying so you know what you are getting.

                      If I could only have three unis and I rode trials, I'd have a 19, 29, 36. If I rode trail trial and muni I'd have a 24, 29, 36. If I only rode street I'd have a 29 guni and a 36, maybe a 36 guni.

                        good choice. I love mine! Lighter than my 26" Oracle and rides like my 36er except manageable off road.

                        get the 165/137 cranks. I love mine! 137 is plenty short for the road and you will appreciate the leverage of 165 off road. Then, when you get a 36er (the only real road uni), you can go super short on cranks.
                        My greatest fear is that, when I die, my wife will sell all my unicycles for what I told her they cost.

                          For such a simple sport, the buying choices for uni are awfully complicated!

                            Yep I was amazed how light it is for such a beast. I was
                            Able to hop steps with out too much of a problem. I am used to my trials so I could feel the rim flex which is weird. Forgot to mention that is enjoy idling and hopping at lights so probably the 29 is the way to go for my commute.

                            Why are 150s standard on the kh29 as opposed to the 165s?

                              Because Kris is a far more talented rider than you and I. He does make a good point that shorter cranks minimizes the dead spot when rolling rocks and roots riding MUni but I would listen to Josh's advice. He specs unicycles for the common man. Kris specs them for his own preferences. Not that there is anything wrong with that. If you've got mad skills, shorter cranks are the way to go. Ben King can climb bumpy hills on his KH29 (150mm Moments) that I could not get half way up on my 26" Oracle with 165 Spirits. Like you, I saw that KHU specs the KH29 with 150mm cranks so that is what I got. It was not long (I gave them a fair shake on 3 different trail rides) before I put them up for sale on the trading post and ordered myself a set of 165's. It was a costly mistake that I'd just as soon see you not repeat. Of course it all comes down to personal preference but if you are just getting into MUni, I'd start with the longest cranks I could get my hands on.

                                Thanks for the kind remarks. Of course, it does ultimately come down to personal preference. However, I'd caution riders against thinking that 150 mm is "short". In the worldwide unicycling community scheme of things, anything longer than 140 mm is generally considered long, on average, by riders of the full spectrum of abilities. Based on my crank sales, I'd say that cranks longer than 150 mm are mostly a North American preference.

                                For Muni, in the late 90's I rode 175 mm cranks, then 170 mm cranks (which were spec'd on KH munis for a few of the early years), then 165. Now I currently ride 150's on my KH26 geared uni, and 137's on both my single speed and geared KH24's. On a single speed KH26 or KH29 I'd ride 137's for XC muni (125 if the trails were relatively easy) or longer (150's) for technical muni. The progression to shorter cranks over the years was partly due to improving as a rider and partly due to just wrapping my head around the idea that shorter cranks could give me sufficient control on technical downhill.

                                150's are spec'd on KH unis because it's the most popular preference, not because it's my preference. Good example is the KH36. Other than offroad, 150's are super long for most of the experienced road riders but this group is not the norm, so 150's as standard is a better choice off the shelf.

                                A major influence is a brake. If you're waffling between two length choices, I'd suggest going with the longer one if you don't use a brake, and consider using the shorter option if you do. I definitely would not use 137's on my KH24 for technical downhill if I didn't have a brake. With proper use, a brake will take care of most of the control issues on descents that longer cranks would have, while allowing smoother pedalling.

                                Kris
