    Nextie 105mm single/double wall Rim

    Nextie 105mm rims now available! Not a plug from me, just thought i'd share as they look awesome!

    They weigh in at 580g each. The pic shows a spoke hole offset at +/- 2mm but production rims will be offset 5mm.

    Interesting shape. Kind of splits the difference between heavier doublewall and the HEDs.

    I see some very substantial benefits to these for winter riding:

    Compared to double wall rims:

    1. Much lighter
    2. No risk of water getting trapped between the walls
    3. Using neoprene washers can be setup tubeless without tape

    Compared to existing single wall rims:

    1. Smooth outer shape should minimize snow retention
    2. Much less expensive
    3. Wider than the HEDs and more available than the Kuroshiro rims

    I like the shape because the reinforcement against spoke pull-out is thick.

    Having carbon fibers joined around a small hole is never a fun time, so anything to help in those zones is good. Especially true if they are drilling to create the holes (vs in-molding).

    Given my size and bike weight (about 260 total), I'd be inclined to go with the washers even if I could get a good seal without them.

    Probably similar options as the 85mm Xiphias.

    Wish i had a spare $2k right now! I'd get a pair of both the Xiphias and the 105mm to complement my 65mm.

    Oh the agony! Which one?

    Lol!

    I'm a fan of 105mm rims for soft snow. I've been on Kuroshiro's for 2 seasons. I think more people could benefit from the width than are currently using it.

    That said, I'm gonna wait a year, at least, until I encourage people onto these. The cross section just doesn't give me confidence. Especially considering how far 'out' you can get on a bike shod with rims this wide, and how absolutely hosed you'll be if something fails and you have to walk back.

    ^^ I get it. Certainly don't want to be miles from shelter and have equipment fail in extreme conditions. Equipment that often is taken for granted when it's working but when fails the realization quickly comes that your life may be on the line. Been there, done that.

    The Kuroshiro 6105 are a single wall rim where as the Nexties have a liittle more mass and a double wall section. Of course the 6105's complex structure and (I assume due to nearly three times the cost) the quality of the layup may more than make up for any gains in strength from Nextie's bit more material and splitting that material into a single/double wall design. I don't know.

    What I do know is that I am not likely to buy a Kuroshiro rim at nearly $1k, although I would love too.

    It appears to me that Nextie is making fine rims these days. I really have been loving up my Nextie Black Eagles! I have little doubt the Xiphias or the new 105mm rim will hold up to my weight.

    I am running the Dengfu FM190 and FM191 and it will clear a Dillinger 5 and Jumbo Jim 4.8 mounted to 100mm rims. There is plenty of room for those tires. it would be able to clear a wider rim with these tires. It would not be able to clear the 5.05" Vee tire though.

    Are most rims drilled for spoke holes or are they molded? and the the wide rims ever fail in flat part of the rim? by this i mean not the lip part. i have seen people have a rim strike at low psi and smash the lip but has anyone ever had one break in the flat part.

    Asking because i had heard that the width makes them stronger and i wonder if the double wall is way over built and a single would be fine.

    thx

    I don't know either. That's why I'm going to wait and let other people be guinea pigs. I was an early adopter with Nextie and that didn't pay off. They've slowly figured their designs and processes out, but they've basically used the consumer as both their R&D facility and financier to get there.

    I'm not going to try to talk anyone into the Kuroshiro's -- because they're at that level of expensive. That said, a built set is more like double what these unproven Nextie's will come in at. Still a lotta coin, just not quite to the level of triple that you've suggested.

    ^^ I was looking at it from the perspective of rim cost but true the hubs and spokes are part of the neccessary kit.

    I don't know but these are drilled. I would think from a carbon layup process that it makes sense to drill. I would also think there is a good bit of leverage from the lip of rim to the spoke holes, however the arch or continuos arch (in awheel or rim) is perhaps the strongest forms around. Ha! Pun intended.

    Remember, when looking at the profile, the rim/wheel is not just a cross section but that 'profile' in a continuous arch around the wheel. I was thinking the same thing that it looks weak in middle but then realized the "arch". It is extra thick and time will tell as mikesee wisely says.

    Overbuilt is fine w me, especially if it is only an additional 55g per rim. Plus, as mentioned above, the shape may shod some snow that a single wall may not.

    Shipping rims from China is a not-insignificant part of the cost that must be factored in.

    Yes, also true.

    Last i knew, Carver at bikeman sells nextie carbons and will ship much cheaper. He still has his cost but i think it's still a savings.

    Might have, I'll have to check when I get back home from this trip. I know the bike is 22 or 23lbs depending on if I'm running the 65mm+D4s or 90mm+D5s. Held up to racing last season great. Haven't used the rear dropout position yet, but I might go for some 2xl tires to try it.

    Good question. Seeing that they specifically list 5'', I assume they refer to the 2XL, even though Chao Yang has a 5.5''.

    At ''industry test standard'' 20psi, the 2XL measures right on 5.0'' on a 80mm rim, 5.2'' on a typical 100mm and I actually measured to 5.3'' for a brand new, unstretched 2XL tire on the Fatlab 100mm (unfortunately, this one had an OD that was too big, so the bead of the tire snapped'')

    Big question is chainstay and seatstay clearance with 100mm rims.

    I'm running 2XLs on 100mm rims on a Blackborrow. The clearance is very tight at the edge of the tread but plenty of clearance at the bead. I'm wondering if I will have problems with 105mm rims.

    I may be wrong but I don't think any frame with 100mm bb will fit 2xl on hundies. Carved omega beast and blackborrow have 120mm bb.

    I would also like to know how this fits on a Blackborow? Running mine DS. Was looking at the Nextie Kylin, it is also a 100 mm rim. Anyone know about the Kylin?

    Erd

    The ERD listed spec is the same for both the Xiphias 85mm and the 105mm rims at 542mm

    Clownshoes listed ERD spec is 543.5mm.

    This might be close enough depending on how they were measured to use the same spokes and hubs of a CS wheelset, provided the spokes don't stick up through the nipples or they have enough thread engagement. Especially on a single wall rim.

    Anyone have an accurate measurement of a CS ERD?

    @joeduda: When the 105mm rim comes in perhaps you could publish the measured ERD here.

    Adding 3 mm, for neoprene washers, to the 542 claimed ERD here is what I get for spokes. I'll probably just use 265mm spokes on both sides.

    3mm?! Seems quite excessive given how thin they are, and how much they smunch under tension.

    The ones I plan on using are neoprene bonded to stainless steel. What would you recommend? 2mm, 1mm?

    Hard to say--its cone shaped so a bit tough to measure--maybe 1.5- 2.0 mm. Here is where I got the idea to use 3mm:

    So i picked up my built wheels from the shop last night. I got these to build up a max flotation fat bike, my old Borealis Yampa that ive had for a few years. Ran a strip of packing tape over the nipples and mounted Bud and Lou Tubeless. The wheels look ludicrous on the bike, they are friggen huge, kinda of gives it the look of a "donk" automobile. Hopefully i wont need to ride the lou on the rear at "flat" pressures cause it is gonna rub. Seems fine at around 3-4 lbs though. Now all i need is some deep snow.

    ^^ Cool!

    How about some pics? Let's see 'em!

    Same wheel tire combo I'm considering w the exception of Bud in F/R. It is my understanding that Bud and Lou fit very loose on many rims.

    How tight or loose did they fit on the 105's?

    I will try to take some photos this weekend of it out in the wild. It has been my experience also that Bud and Lou are loose fitting on all the rims i have tried them on. Not the case on these rims. They are not overly difficult to mount on the rim but when i tried to remove the front tire last night it was damn near impossible to get it to break the bead by hand. i had to lay them it the floor with a towel beneath and step on the tire to get them loose. Definitely don't have to worry about them coming off the bead from low pressure.

    Sweet!

    Can you measure the casing width at 20psi (or 10psi if you don't want to take them to 20)
    Please
    (nice to get an idea about the diference vs. 100s. I have the data on 103s, but they were non-tubeless type rims)

    I don't really have calipers to measure them with, but i will see if i can come up with something. I did air them up to close to 20 to make sure they seated completely and at that pressure they rubbed. These tires have about 3 seasons on them so they are probably stretched as much as they will ever be. Give me to the weekend and i will measure them up.

    It turns out that the spoke channel has a bit of a concave shape that prevents the washers from sitting completely flat. They still seal, but they add quite a bit of length. I should have added a full 5mm to the ERD and gone with 267mm spokes. The 265mm spokes leave about 2mm of exposed threads when used with the washers.

    I'm semi-considering upgrading my Sarma rims to these (I'd save nearly 400g rotational weight) but won't on principle. I want 111mm rims.

    Guys, open your eyes...

    You DO NOT NEED any stupid washers or whatever to have these new nextie rims (85 and 105 mm premium ones) well-sealed...

    Just go for the correct nipples (e.g. Sapim Polyax) - and the wheels would be perfectly sealed just with the sealant (by the same principle, as it comes on the Kuroshiro wheelsets).

    I had finished already about 15-20 wheelsets, built like that (Nextie Xiphias rims + Sapim Laser spokes + Sapim Polyax nipples) with the great success... not any problems - nor during assembly, nor while riding then on the trails!

    Good luck!!!

    Good to know. I was curious how well they would seal with just polyax nipples. I should have my rims in a week or so, and bought some tape just in case, but am happy to know I'll probably not need it.

    Thanks!

    A question one I have for thee:
    How's the effective casing with on these vs the same tires on a 100mm?
    At, sayeth, 15 or 20 psi.

    Yes they have that on my Black Eagle 65mm rims.

    Can you please confirm the ERD of the rim is 542mm w/out the washers? What is the ERD with washers?
    Btw: I doubt you really need the washers although not a bad idea.

    That is the 3K weave.

    I'd use a 547 ERD with the concave 18-8 Stainless Steel / Noeprene Bonded Sealing Washers from McMaster-Carr. Without the Washers, I'd use 542. Given my weight (over 210 lbs fully kitted plus a 50 lbs bike including gear) I think the washers are a pretty good idea even if you might not need them in the shop.

    I ordered a set from BTLOS. One weighed in at 560g and the other 590g. Excellent quality. They built up really nice laced up to a I9 Torch 197mm rear and a DT Swiss Big Ride 150mm front with Sapim Laser spokes and polyax nipples. I tried to run them tubeless without tape but one of nipples kept blowing air so I taped them with 2 wraps of Maxi 49 Polyester/Silicone Single Coated Splicing Tape 1.5" wide. Feel better about having the tape anyway incase of the rare chance of breaking a spoke. Sealed up great and aired the tires up with a floor pump.

    Espen, what do you mean by that?

    My 2XL had come about 132 mm in the width by the knobs, and even bigger in the middle of tire wall (the casing)...

    P.S. Yeah - there is a difference between the 100 mm and 105 mm rims... on the second ones the casing goes noticable wider (and even wider than the knobs, for the most of the tires).

    I ordered 2 singlewall wheelsets from Nextie: 65mm and 105mm, both laced to DT Swiss hubs.

    The 65mm wheelset arrived around 3 weeks after placing the order; the other around 4 weeks.

    Both wheelsets included 2 spare spokes, valves, and tape. That was a nice surprise.

    The tape appears similar to Stans tape. It's about 25ish mm wide, and like the Stans tape, doesn't have much give. With the singlewall design, the spoke nipples protrude into the rim. I did not expect that the tape would work well if I tried to pull it over the protruding nipples, so I proceeded to set up the wheels for tubeless without tape.

    I mounted Maxxis Mammoth 4 inch tires on the 65mm wheelset. I had a hell of a time getting the tire bead to seat, even with an air compressor. I went back to square one, thoroughly cleaned the tires, and applied lots of soapy water and this time got them to seat. There was a bit of Stans sealant leakage around the nipples and at the tire bead, but after shaking them around, they both sealed well after a day.

    I mounted Surly Bud and Lou 4.8 inch tires on the 105mm rims. I also had to struggle with these, but the bead seated a little bit easier. I used Revo sealant this time, and it did not go well. Lots of weeping and bubbling at the tire bead. Both tires were losing air too quickly for practical use.

    I unmounted the tires, thoroughly cleaned both, and remounted using lots of soapy water. Instead of the Revo Sealant, I used a DIY recipe found here, based on recipes discussed on MTBR. I used more sealant this time; at least 3 syringes' worth per tire. The tires continued to bubble and bleed a lot right at the bead, but sealed well after about a day.

    I ride a DenguFU FM191 frame. Previously, with the Bud and Lou on 100mm rims, the tires had between 5 and 10mm clearance at the chainstays. Now with the 105mm rims, the clearance is maybe 5. It's pretty tight. When I look down when riding, the clearance looks ok, but I don't know if it's the same story when cornering. I will need to check for frame rub. I really like the traction the Lou gives me. It would be a shame to have to go down a tire size due to lack of clearance. Clearance in the front is a non-issue. Plenty of room in the front.

    I will post some pictures this week.

    The first 4 are of the 105mm rims before mounting tires on them. The last 2 show the 4 inch Maxxis tire on the 65mm rim compared to the 4.8 Surly Bud on the 105mm rim.

    Looks like a match made in frosty haven!
    If you don't want them, I'll take em!

    It appears you placed o-rings between nipple and rim, yes? I wonder if that would be too squishy or flexy??

    I would put a piece of tape over those holes before getting any tubeless fluid in there.

    I built 4 of these a few weeks ago. I put a blob of glue (shoe goo, actually) over each of those 4 holes (per rim) and let it cure before inflating them tubeless.

    Wish they did the single wall in 27.5x80-90mm

    Under 600g would be slick

    I taped over the 4 small holes. I failed to notice holes in the 65mm rims before I set them up tubeless.

    I bought the wheels pre-built from Nextie. I don't believe they used o-rings between the nipples and rim, but I don't know for sure. A bit of sealant leaked out at the nipples at first, but they sealed up eventually.

    About 4.8 to 4.9 inches. I have a digital caliper measurement tool, but the jaws aren't long enough to reach the widest part of the tire.
