  1. Hey everybody!! I finished putting together my 36 with the Kris
    Holm/Schlumpf hub a couple days ago, and have gone on a couple rides
    with it already, and I have to say it is AMAZING. Some observations:

    High gear is quite crazy... I can cruise maybe 3-4 mph faster than on
    my ungeared coker with 102s, but it's decently scary, and any
    irregularities in the road really hurts my speed, because I end up
    choosing to slow down rather than attempt to accelerate over them. I'm
    100% certain that with some time and with some riding, my speed will
    increase just due to the fact that I'll have geared coker riding in my
    muscle memory. Gotta go out and ride! On flat ground, I've pedaled it
    up to 21-22 (ish), but on downhills, I've probably only ever hit 20.
    18mph feels quite natural and sustainable. I think I need shorter
    cranks...

    With 165 cranks, I bounce too much. Florian sent me the 165 Moments
    instead of both pairs of dual-drilled cranks (125-150 // 137-165) like
    I ordered, but at least he charged me for what he shipped me; all I
    gotta do is get me some shorter cranks now. And seriously, it's not
    even a big deal, because riding this thing is so amazing that I just
    don't care at all right now! 😄

    The slop is really good: though it's very noticeable when riding
    slowly, it blends in entirely while you're actually riding somewhere.

    The hub is beautiful! It really looks so cool... Kris and Florian did
    an amazing job making this thing, and if you have the money and end up
    buying one, I guarantee you won't regret it. It's a work of art!

    Descending in high gear without a brake for a long period of time will
    destroy your quads! :o ... I rode up and down Mt. Diablo (10 miles and
    3,200ish feet) two days ago and still feel like jello when I walk. (I
    hadn't gone on a bike or uni ride for about 3 weeks prior to that, but
    still, usually nothing taxes my muscles like that, even after being
    that long out of it).

    XC MUni on a 36 inch wheel with a splined hub and long cranks is just
    godly! You can roll over just about anything, yet the long cranks give
    you all the torque you need to power up some pretty steep hills in low
    gear.

    Shifting on the fly seemed impossible initially, and then I figured it
    out... you hit the button with the butt of your heel as the pedal goes
    down in front of the hub. After maybe 30 attempts to shift since 2 days
    ago, I can shift about 80% of the times I attempt it, with one
    "attempt" being defined as "take as many pedal revolutions as is
    required in order to get the button to pop in." Usually, to shift, I'll
    twist my heel in and end up hitting the button three or four times
    before I actually get it to pop in and shift the hub.

    Shifting at speed seems better than shifting going very slowly, due to
    the small period of freewheeling when the hub is "between gears". When
    you're moving with a little bit of speed, the cranks lock in much more
    quickly, sometimes so quickly that you don't even realize that they
    were just freewheeling on you for a fraction of a second. I've only
    ever fallen due to a shift when I've been going really slowly (though I
    haven't ridden much yet, of course!)

    The frame is beautiful, and LIGHT! It's stiff as hell, and when I ride
    muni with it, it feels like I'm on a real muni and not on a 36er.
    Except for the speed, of course! I can't believe how much lighter the
    KH36 frame is than my old Nimbus. Guess that's the difference between
    aluminum and steel! The seat tube is a bit long, but that's because
    it's a prototype. Kris warned me about this, and luckly, I'm tall
    enough so that I can have the seat at the proper height and not be
    stuck with it too high, so, for me, it makes no difference. It just
    means that not too many shorter people will be able to ride it.

    and.... PICTURES!! 😄

  8. What a beauty!

    Could you drill a 36er rim like a 19" rim for weight loss? I think this
    would be a good way to lose weight.

  9. @Danni: I'm sure you could drill the rim out and have it survive, but
    given the way I break just about everything I touch, I'm definitely not
    going to do it to my rim. You can definitely drill an Airfoil rim...
    ask Ken Looi (GizmoDuck) about that, I think he drilled his. UDC's
    stealth rim, which is what I'm running, is a bit lighter and I don't
    think I'd want to drill it. I'll leave it to Ken to try! 🙂

    hey, the Terry: The hub and cranks ended up being $1476 total straight
    from Florian, which seems a bit high ($1268 hub, $75 cranks, then
    shipping?... maybe he charged me more due to the weak dollar? I was too
    excited to look at the receipt and think too hard about it, and I still
    haven't now that I'm sane again). The rim and tire together are just
    over $160, the frame (shipping in late June, far as I know) will be
    $200? I paid Kris $140 for this prototype (140 including the shipping).
    The seat is $54 on UDC I think, the seatpost is $20, the spokes are $2
    each ($72 total), and I paid $50 for the pedals on eBay. Added up...
    hmmers... that makes $1,952 plus the tube. Just under $2000 is my
    answer.

    As for where I got the frame... I originally emailed Florian with some
    questions about the hub, and after Florian got back to me, Kris replied
    with some more information. This resulted in a little conversation,
    where it came up that I wouldn't be able to run the hub in my Nimbus 36
    without welding on new bearing holders, and (not knowing he was working
    on a KH36 frame) I said "guess I'll have to wait for your KH36 to come
    out, eh? 😉." When he messaged me back, he told me he had a prototype
    sitting in his office that was perfectly good except for too high of a
    crown, and that if I was tall, it'd work out... and he sold it to me
    for $140!

    I am supremely crazy lucky to have been able to get this frame, and
    Kris, if you are reading this, THANK YOU! Your unicycle hardware is
    just beautiful. Like my Macintosh and Cannondale. The effort you put
    into making a superior product really shows, and I know I'm riding
    something that's really loved by the person who created it. BTW, Up
    here in Northern California, I've had hard core, elitist,
    gotta-shave-the-two-grams road cyclists look at my cranks and say "are
    those made especially for unicycles?? They're beautiful!"

    I can't wait until I'm a good enough rider to fully even take advantage
    of this beast. It's going to be super fun getting there!

    I think I read something about it being available sometime in the

    No it wasn't me...I think Pete Peron is the man with a drilled airfoil
    rim.

    That's a beautiful Uni Chuck. I had the opportunity to ride a KH
    Schlumpf hub and it's a much nicer hub than the 2nd Gen Schlumpf hub.

    I'm getting a Triton frame and the Nightrider/Stealth wheelset.
    Hopefully in time for RTL, if not then Unicon.

    Descending in high gear without a brake for a long period of time will
    destroy your quads!

    Chuck-
    Thanks for the great write-up. I should be getting my KH/Schlumpf hub
    in the mail tomorrow! (Frame sometime in '08🙁 ) I'm curious about
    your impressions descending in high gear. Do you think it was
    especially tiring because you're not able to spin as naturally as you
    do in 1:1 mode? Are you going to try and get a drag brake set up on
    it? Did you ever feel the wheel wanting to slip out of control from
    speed?
    Thanks again. Congrats on your awesome new Guni.

    Hey Ken,

    what's nicer about the new hub? Is the ride better? Obviously the
    attachment method is more convenient, and it's got a wider bearing
    spacing and is stronger, but it'd be interesting to know if there's a
    difference in ride?

  20. My 1,000,000 questions:

    Did you tighten the crank arm bolts with the 6mm hex tool that Florian
    provided? I posted about how it had a little bit of play in the nut
    while trying to tighten it(for me at least).

    Also, have you had any trouble with a crank arm coming loose a lot?

    I know what you mean about your quads killing you after riding in high
    gear for a while. Unicycling on a ungeared 36er with small cranks does
    not wear out my legs anywhere near as much as a geared 29er in high
    gear.

    Have you weighed your entire unicycle yet? My geared 29er was about 17
    pounds with everything on it (which is kinda heavy, but that is due to
    the hub, the moment cranks, the snafu pedals, gb4 bars, and rail
    adapter).

    Have you had any shifts where it didnt shift as you expected? I find
    that sometimes if I am not applying a lot of pressure to the pedals
    (like when I am going down hill) if I try switching to high gear from
    low I am able to pedal a few times before the shift occurs. This also
    might be because I am not hitting the button as hard as I should.

    Aaaand one last question: who built your wheel and what size spokes
    did you end up using?
