  • I just did a major re-configure of my geared 26 commuter.

    After swapping the studded winter tire for a summer one it rolled so much faster and the 137s felt a bit long. I decided to throw on 127/150s and at the same time swapped my conventional fusion freeride with a long handle for a Zero with no handle. The thought was to go with a minimalist setup primarily for MUni using the 150 holes but have the option of 127s for a road ride.

    I spent the night in the city Friday night and in the morning rode with a friend to her work. 12km and windy as, other than the wind it went really well.

    I was worried about riding without the handle but it turned out not to be a big deal, and I really liked using the 127s with the moderately fast rolling tire. The wind took a lot out of me and I had to ride a few sections in low gear but with the shorter cranks it didn't feel as silly as with the longer cranks. It was the first time I felt that both gears were really helpful on a commute rather than just high gear.

    The Zero saddle I am not quite sure about yet. It didn't feel too bad on the way out but the first 3-4 km on the way back I was a bit tender before numbing. I like the slimmer profile but the Zero might require padded bike shorts to be truly comfortable. I started with one spline visible at the back but tipped it up one more notch after a while. I also lowered the seat a bit more than I would have with a regular saddle.

    • OMG!!! How do you fly this thing???

      I just came back from my first ride practice with the 29 Guni (KH).
      It was both hellish and amazing all together.
      It took me about 10-15 minutes to get on this thing (freemount) and actually being able to ride. It felt as if I was in a parallel dimension in which I do not really know ride unicycle...
      After I managed to ride a bit and felt really confident in what I was doing it was pretty good but still kind of stressing.
      The weird thing (and I'm sure you all been through this) was that when I reverted the gear back to 1:1, it took me several minutes to be able to freemount - an action that I could do while I was even asleep in the middle of the night with my eyes closed... it really blew my mind.

      Can anyone please calm me down and tell me I'm going to be alright with this?

      Thanks

          • Back in 2008 when I got my G36, I was also shocked - I did not just "learn" it instantly like it seemed others did. Even though I had ridden way over 10k miles on ungeared 36, it was like being a beginner all over again. After 200 miles I wasn't struggling so much. After 500 (including the India Uni tour), I was more comfortable. 9000 miles later, I am still learning and improving.

            In the beginning I made one rule: never mount in high gear. Always practice shifting. Learning to ride slow seemed to help so sometimes I would stay in high gear while having to maneuver around people, cars, whatever. Then try that while shooting photos etc. Also early on I tried practicing just shifting: go at somewhat slow speed and shift up, down, up, down, ... as quick as possible. You can actually do it shifting every half turn.

            All the time you put in learning is worth it! If someone took my Gunis away I would ride a bike!

              Just wondering if there's much play as you turn the cranks? i.e. do they respond immediately or is there a delayed response from the hub?

              • Guys, thank you so much for your feedback - it really puts me into correct perspective now that you've shared it with me.
                It's not easy being pretty much the only one in Israel right now riding this thing with no close reference. But you are the "game changer" that allows me to go through all the obstacles

                Regarding the "play", it's good thing you've mentioned it because there is something like 1 or 2 mm of 'freedom' when moving the cranks back and forth before the actual wheel turn occurs.
                I thought at first my cranks weren't tightened enough, but they were fine of course.

                Is this 'freedom' of the back and forth movement by design?

                Thanks

                • The little play comes from the design, I noticed it at the beginning, but I nearly don't feel it anymore now.

                  The balance trick in 2n gear that makes you feel like you don't know how to ride a unicycle anymore will disappear with time and practice, especially if you use 150's, cause with shorter cranks it is worst (in my case at least when I started).
                  At first you are nervous, like a beginner on a unicycle, and it takes much efforts to pedal and you struggle to keep balance, but once you start to be relaxed it becomes easier, and as it becomes easier you get more relaxed and so on.

                  I have also experienced the "how to mount in 1st gear" after a little ride in 2nd gear.
                  This will also disappear with time.


                  This afternoon I tested the 2nd gear of my G26 with only 15 PSI in the 26x3 knard tire.
                  I was surprised how stable and fast it was, at the price of more efforts but not so much.

                  I played with a jogger, I tell more here:

                  • @one4all. Yes, I believe it is. I was wondering did the new schlumpf hub have this 'play' and it does. Is that looseness felt on each revolution or is it just on the first revolution as you begin riding?

                      Today I got my new KH29 and schlumpf. The Knard wheel is fatter than on my Nimbus Oracle 29", so it took a few times riding off in normal gear. There certainly is some play when taking off, but once you keep pedaling there is no more looseness.

                        I will keep all of your post as that is exactly how I experienced it today when I finally got the new KH29 and schlumpf. After a few tries, I felt ok again on the 1:1 gear, but I've never ridden geared before and I have no idea how to freemount in highgear. I also tried holding the wall, but the wheel rolls too quickly. I have no idea how to tackle this. I am sure that while shifting to another gear, if even I can hit it with my ankle or heel, that it will be an immediate UPD. It would be nice to just ride it in high gear for a few rounds to get the feel first. Please tell me how.

                              Gotta try everything once I guess. I've been riding many kilometers on the Nimbus 29" and it would be nice to go a bit faster with less effort. I guess if I start wearing knee pads now, I will dare a bit more

                              • 20" Schlumpf Update

                                I spoke on the phone today with a representative of Silva Cycles, the bike shop who installed a Schlumpf into a 19" wheel for me. After four days of riding, one of the cranks loosened, and the shift button got stuck. I was unable to remove the button to assess the damage, so I sent it back to Silva.

                                Now, I'm not very technically minded, and I'm hoping that someone else on the forum follows up on my post to clarify the situation...

                                The Silva rep. told my that he was only able to tighten the crank bolt to 18 nM before it bottomed out, and this was no where near the 40 nM specification quoted by Florian Schlumpf. The rep. told me that the situation could be remedied by refashioning whatever the part is that the crank comes flush with...when it's bolted on, but that it takes a machine shop to do the job. Silva noticed the same problem when they were testing out a G36 they were putting together.

                                It sounds like the problem can be fixed, but since, I understand, this problem is without precedent, we'll have to see how their solution plays out.

                                Needless to say, this is very concerning news. Of course, I hope the problem can be remedied. I am curious how many people have already put together Schlumpf unicycles, and what their experience is tightening the crank bolts, if they used a torque wrench, if they bottomed out, etc. My understanding is that this issue applies to EVERY 3rd generation Schlumpf.

                                I am very happy to work with Silva Cycles on this, because without their help I'd be SOL.
