Great !
Guess who just pulled the trigger 
Canāt wait to give it a spin 
Let us know how it rides with the new tyreā¦ I might get one in the near futureā¦
Sure.
My first tire was a TA , about what? 2300 gm? smooth but heavy! max recommended PSI : 32PSI
then I put a light Nightrider (1700-1800gm lighter than the first NR batches).
Max recommended PSI: 65PSI
Then I built a G36 with the new Qu-Ax King George tire (1700-1800gm) which
feels like a mixture between the NR and the TA.
Max recommended PSI: 50PSI (just between the TA and the NR)
I still use the NR tire on my ungeared 36x145.
Where I ride, there is a lot flat paths but also a lot of climbs and slopes.
I can not miss a tire that is 400 gm lighter : especially for the climbs.
It will go on my G36x150.
Yeah!
Xmas is early!
Eager to read your feedback!
btw: you still have your 29" Hookworm? -Thinking about selling mine very cheap, a pair could go easier maybe.
Feedback is not for right now, Iām having a break, didnāt ride a single time those last 3 weeks, those short, cold, windy and rainy days are killing my motivation, but Iād like to ride my G36 (KG tire) at least once before putting this new lightweight tire, to better feel the difference.
And I still have a BUNCH of tires in which, yes, there still is my 29" Hookworm.
what about 3 ?
Iām afraid I did not get it: Will there be a 32er Version or not?
First test ride of the 36" Nightrider Lite : review
For those who missed it on the Unicycle Chat FB page or for those who will read this thread in the future, here is a copy past of my review.
Test ride of the new 1400 gm 36er tire :Nightrider Lite.
Context: My last G36 ride was 6 weeks ago.
After that I only rode my not-geared 36er once one week later and thatās all.
So my stamina is down to zero.
My experience with 36er tires is:
TA tire (2100-2300 gm) on my Qu-ax ungeared 36er
Nightrider (1750-1800gm) on the same Qu-ax 36er
King George (1750-1800 gm) on the G36
And now the Nightrider Lite 1400gm on the G36
The tube I used with this tire is the same as with the KG :a Michelin Airstop butyl A3 700x35-47 with schraded valve, 170 gm.
The tire was inflated at 52 PSI/3.5 Bars.
This test was during a 1h45-2h ride on a 22 km loop that has mixed parts, some complicated, some way easier and clear (bike path), a bit of uphill, a bit of downhill.
Some front and side wind, cold but sunny, and with some pauses to take pictures.
This was also the opportunity to test my latest DIY on the X-Chromosome Handlebar and my new audio Mp3 stuff, but I will focus on the tire.
Now this new tire: just wow !
I immediately felt the 400gm of rotational weight saved in comparison with the KG.
First the freemount. My freemounting technique is special: I freemount the uni and immediately do few hops in order to move my second foot until it is exactly where I want it to be, then only I start to pedal.
Each time I did it It was noticeably easier than how it used to be.
Second, accelerations : the wheel is more reactive when I want to accelerate or when I want to slow down.
The resistant torque at the pedals feels lower.
Itās still a 36er tire with some inertia, but itās clearly a step toward smaller unis in term of feeling.
In low gear, with my 150 spirit cranks I could easily ride at 12-13-14 mph (19-22 km/h).
In high gear I found the guni stable, Sometimes the resistant torque at the pedals was in high gear nearly like what it used to feel in low gear with the previous tire.
I didnāt dare to go faster than 26.8km/h (16.75 mph) in high gear because I didnāt want to take any risk with this random wind, but I was quite comfortable at 15-16 mph and I didnāt feel the need to go faster.
The transitions from low to high gear (or from high to low) were smooth, so I shifted way more often than I used to.
The inertia being lower, keeping a constant cruising speed in low gear may demand a bit more energy, at least theoretically , but in another hand, like I said, itās easier to accelerate and to slowdown.
Which leads to the third point: maneuverability.
I found it clearly easier to handle, to make sharp turns, to control exactly where I want to go on complicated situations.
There again it feels a bit more like a smaller uni.
also uphills were easier.
4th point: Sensitivity to Road camber :
Where the hell is it gone? On this loop I use to struggle with camber sensitivity on several parts, but with this tire: it never happened. I mean ā¦ it NEVER HAPPENED !
5th the buzz sound : well I canāt tell, I was riding with Joe Satriani playing his electric guitar just behind me 
But the few times I turned it off I donāt remember hearing anything.
As a conclusion about this new tire: Itās the lightest one on the market right now and I pretty much felt it : easier to accelerate and to slowdown.
Itās not only lighter, I found that it performs better than my previous tire in term of maneuverability.
Very low sensitivity to road camber, which is a big plus to me.
It was nearly like If I never stopped to ride, (except that I was suffering from low carb at the end).
I was supposed to be an extremely short test ride, but I enjoyed it so much that I just continued to ride.
I want to thank Unicycle UK-Staff for this great job on the new 32 and 36 tire. it seems that it was complicated to make it possible, but you did it! well done.
Now about the X-chromosome long and short position, with the strengthening DIY and the bar-tape, itās just perfect.
The audio system works like a charm and made the ride even funner.
I hope you guys enjoyed this review of the new 36er tire.
Pascal.
thanks for nice review
Tyre Blown off Rim
Morning Folks,
Some info with respect to the new Nimbus Tyre.
I bought Mike Fuleās old Nimbus 36er with the Aero style rim. It came with a TA tyre and a Foss tube. A week back I bought the new Nightrider Lite tyre. I replaced the tube with a Michelin 29er tube as I donāt have patches for the Foss tube. Iāve used 29er tubes for years on my 36er mountain bike.
The tyre is great to ride and the reduction in rotating mass made a noticeable difference.
The tyre has been on for a few days at 45 psi. Last night I inflated it to 55psi and parked it. The bead seat was nice and even. A couple of hours later, as my good lady was walking past the uni, the tyre blew off the rim. After the screaming had finished, I realized what had happened.
So after a chat with Roger this morning, his conclusion is that the tyre is not suitable for the older style aero profile rim, due to the narrow profile and possible slight reduction in bead seat diameter over the Nimbus rim. Roger also thought that the 29er tube might not have helped the matter.
So there you have it. Donāt buy this tyre unless you are fitting it to the latest Nimbus rim. Itās back to the TA tyre for me and I suppose I need to keep the Nightrider tyre until I build a new 36er wheel.
Partex
D;
Sorry to hear about the tyre snags.
I was about to pull the trigger on a (completely unnecessary) Lite upgrade for mine to coincide with swapping to a 29er tube for weight loss.
Iāve got a full-fat Nightrider on a Stealth rim. If you are interested in a part-exchange swap let me know! It would help me justify my purchase if I can move my old one on to someone who would use it. Itās a few years old but plenty of life left in it. I wouldnāt be asking a lot for it and Iāll give you what you paid.
No pressure (well, maybe a few bar! :D).
Can anyone confirm if the original Nightrider would be more compatible with the aero rim than the Lite? And if the Lite would do OK on my Stealth (not Stealth 2) rim? Cheers!
Or sell it to me !
youāre welcome.
Sorry for the all packed text, I didnāt notice that the paragraphs disappeared when I copy/past my review.
Good to know !
unfortunately, that means that my ungeared 36er (very old Qu-ax chromed model) will never have this tire.
Thanks for your review.
I have an additional comment and a question to ask to UDC people (or any other guy who can answer).
First: the additional comment:
By looking closely at this new tire, I have this strong feeling that the section shape is rounder than the previous version.
this could be explained by the thinner sidewalls and the softer material, my tire inflated at 52 PSI looks more āballoonā shaped than my previous tires.
In consequence, when looking at the tire from behind, the threaded surface looks like a portion of a circle that would have a smaller radius, in comparison with the older tires.
I donāt know if this is a positive side effect of the softer material, like I suggested, or if this new tire has purposely been designed to have its threaded surface a bit less squared/flat, but I think that could explain why the sensitivity to road crown/camber is lower (At least according to my feelings and in comparison with the KG tire).
Anyway itās a really good thing!
You people can juge, I took a picture of it.
On the picture it looks a bit less round than what my eyes can see by looking at the real tire, but still, you can see some roundness of the shape.
I post the original picture, and the modified picture where I removed the rubber pins (Paint, not Photoshop), so that you can better see the circle portion.
Now here comes the question.
There is something I noticed by looking at this picture : (from kris holm website)
or even this picture of 36er riders (hello Nathan and Kevin )
I see a gap between the top of the tire and the frame that seems somewhere between 1/2 inch and 2/3 inchesā¦
But when I look at my G36 :
The gap is only about 3 mm.
The rubber pins are even rubbing against the bottom of the frame.
I have the latest kh frame.
What does it mean?
Is the new tire bigger in diameter? does it come from the rounder shape?
Or for a reason my frame is shorter than the others?
I measured the diameter of my tire at 920-923 mm = 36.22 - 36.33 inches.
I guess I have to change the setting of my cycle computer, it has been programmed for a 914.4 mm - 36.00 inches diameter.
With respect to the shape of the new tyre, I noticed that the profile had changed. The tyres that I had on my 36er mountain bike were flatter.
On the subject of the overall diameter, I also noticed that the new tyre is bigger. There is less clearance to my old Nimbus Nightrider frame than the TA tyre. I have the measurements from my previous Nimber tyres on the frame drawings I did for my 36er MTB. I will dig them out and check the measurement.
Itās pity and slightly annoying that the tyre isnāt suitable for the older rims. Heyho.
Sorry, but I did not get it. Will there be a 32" Version in the future or not?
THX!
I donĀ“t think so. You have a Maggi mount on your frame. 2017 KH frames do not have them anymore. Only disc mount tab and cable holders.
Then the crown to bearing holder distance might have changed as well ā¦? KH also changed the clearance (width) on the 27,5 and 29 frames in 2017.
You are right, I wasnāt aware there was a 2017 frame, and didnāt notice that magura mounts have disappeared, which in my opinion is a pitty.
But what? The distance from bearing to crawn was higher (nathanās yellow 36er for example) then shorter (mine ? ) then higher again?
And Fat D noticed an increased overal wheel diameter with this new tire too, so maybe itās a combination of both explanations ?
Found the reply from Kris in the ā2017 KH lineupā thread and just copied it:
Here are the vertical clearances for KH frames, measured from axle to underside of crown:
KH20: 268.5 mm
KH24: 338.5 mm
KH27.5: 383.5 mm
KH29: 401.5 mm
KH36: 463.5 mm
Then you can measure if your frame is the same or not. Hope that helps to clarify.
Thanks.
I measured it approximately, and it seems to match.
furthermore, 463.5 of radius x 2 = 927 mm diameter.
so the 2017 frame can take up to a 927mm wheel (with no clearance).
Letās take my smaller measure of the wheel with the new tire : 920mm diameter.
927-920 = 7mm
I see a clearance of 3-3.5 mm between the top of my wheel and the fork, but itās a radius, so if I multiply by two it gives 7mm as well.
It sounds like the 2015 kh36 frame has the same āaxle to underside of crownā distance as the 2017.
And it also sounds like the wheel is definitely bigger.
waiting for confirmations from Kris and from UDC
