It’s my first 36" so I never done it before but it was suprisingly easy (or maybe I got lucky… )
I just inflated it lightly to get it into shape. Just as I would do with a regular tire/tube change.
Then I put the valve through the rim and then I slowly stretched the tube around the rim. Afterwards I carefully made sure that the tube was not twisted anywhere. While slowly rotating the wheel I lifted the tube a bit off the rim to make sure it was as evenly stretched as possible. Last step was obviously to mount the tire itself without pinching the tube.
The reason why I chose this tube is the post quoted below (SV19/AV19 is likely the same except for the valve). He also shares some interesting other points about mounting and using stretched tubes.
Only negative I have to say about my configuration is that a valve length of 40mm is a bit short for the Nextie rim. Look closely at the pictures and its quite obvious. If you are unlucky your pump might not be able to get a proper connection to the valve.
Dang that thing looks sexy! Can’t wait to have mine too!
Good info on the valve. I also worked out that my current spoke will be exactly right if I lace 4x. But it’s always nice to see that it actually worked beyond the theory.
When you replaced all the nipples, you went for 12mm everywhere?
Also did you use washers between the nipples and the rim?
Hard to get on, hopefully hard for it to come off.
Scrap all of your cheap tyre levers though - they’re not worth the stress and frustration. I chucked all of mine after I tried a few decent Schwalbe ones many years ago.
I used 14mm but I believe 12mm would be sufficient as the spokes seems like the perfect length so no need for any additional length nipples. 14mm was just what I could get for delivery early next morning.
The flat black is significantly less fancy looking, but it looks very sleek and I rather like it when performance parts don’t try and show off too much.
KH36 mainly because I got a “b-grade” frame for cheap (because it has black bearing clamps) and I already had the spirit cranks (110/127) as a leftover from my KH27.5 when I changed them recently.
It’s my first 36" so I cannot do any meaningful comparisons of how it rides but I really like it! Fast, very smooth and quite maneuverable.
I (obviously) started out using a wall to get the feel for it but after a few short rides + planned dismounts I tried (static) free-mounting and succeeded in the third attempt
I was expecting it to be something that would require a lot of work to learn but fortunately it seems quite natural and not that difficult. Of course my success rate is nowhere as good as on my 27.5 but it’s good enough that I can just ride off without the need to think about if i can re-mount after an UPD.
It’s not the final configuration as I (as expected) was missing a proper handle after a few mins. My 27.5 has a Handle Saddle that I really like. For the KH36 I will add reinforcement plate to the QX Eleven saddle + a M4O Ursli bar and see how it feels.
Wow, nice, but 13.9 pounds seems impossibly light for a 36er, even with a carbon rim. Is that a carbon saddle base? The weight of the Vee Track monster tire is 3.1 pounds according to their website. Btw, what psi are you running? This rim is hookless but I checked with Nextie and they said you can run up to 60psi. This is with a tube since no current 36er tire is TR.
I admin the claimed weight of 6,3kg is using some cheap scale found on aliexpress but it seems like a reasonable weight for this setup. Also note it’s without any handlebar.
Here I’ve assembled the list of components and their claimed weights by their manufacturers.
The nipples/spokes I’ve weighted myself (I’ve got four left after the build) and the shortened seat post is a guesstimate. Uncut 350mm it’s 220g.
Qu-Ax brake lever mount is also a guesstimate.
KH website states the Spirit Hub is below 580g. Unicycle.co.uk claims it’s only 495g.

I put ~50psi in the tire and left it overnight. Then I reduced it to ~35psi for my first test drive as I’m used to ~30psi on my 27.5 as I wanted to initially have a similar/comparable feel. I will obviously experiment a bit with pressure going forward.

It was actually Schwalbe tire levers that got the job done at the end when the others had failed.
