    You are so right! I'm wondering if Mavic made money all this time with a patent that should never deserved to be granted.

    I'm *just* beginning to seriously investigate carbon wheels and thinking of relacing my hubs to new hoops.
    I found these on eBay, and seem to tick all the boxes: 30mm inner, asym, decent weight, good price.
    Does anyone have experience/feedback regarding the vendor "HulkSports" and these rims:

    They have a less than 97% score on 27 sales, I'd run away from them based on that alone.

    True, but I make a habit of actually reading the negative reviews to learn *why*. Some people are just mouth-breathers.

    Of 27, there's one negative review, and the reviewer checked "negative" but his comments don't match. I suspect he's one of the mouth-breathing idiots that drag down internet sales ratings.

    I'm not defending the seller, I agree 27 feedbacks is a short list, but the other 26 seem to actually address rim quality and are legit reviews.

    That seems to be about 100g too light for a 29' 30mm inner rim. As a comparison, here's another 30mm inner which they quote at 450g ...

    One feature that I wish my carbon rims had (3years old from LB and still going strong) - angled spoke holes. I don't think that these hulk rims have these.

    I'm conservative and I'd only buy carbon rims from an ebay seller that had sold 1000's of rims over a period of years and had a feedback rating of 99.5+%.

    Light Bicycle Promo Video...you gotta see this!

    I was blown away when I saw this video posted in the LB 38mm rim thread in the W&T forum, and I felt that many of the old school Cheap Chinese Carbon Rims followers would enjoy it. Many of you will remember the debate about 100pgs ago over if LB was a manufacturer, or just a reseller, and this included MTBR members going to the actual physical location of LB in China to try to confirm. I had thought the consensus was that they drill onsite, but are buying rims from some other company, perhaps Nobl.

    Well...LB seems to have commissioned some Brooklyn hipsters to make them a promo video to put those doubts to rest. It's far out. It feels like watching a fair trade artisanal coffee roaster promo:

    I returned some LB rims a while back, and the address was not the same as the standard shipping address.

    Haha...

    Whatever rim you buy from China...it'll pretty much be coming from one city. Sooner or later people will start figuring out what factories the rims are coming from.

    The companies that make carbon rims don't make just carbon rims. If you look at some of the facilities...they are bloody huge. They make all kinds of carbon goods. Rims are just one of them. They also make other carbon goods from hockey sticks, bats, car parts, etc.

    I bought a rim from XMapex at Interbike. Now the rim came with a tag. On this tag and on the rim is a part number. Its the same part number thats on Nextie's "Premium" rim.

    Take a look at the part number. On the tag and on the rim. The pic of the rim is a bit blurry, but you can still make out the part number.

    (Cheap) Chinese Carbon Rims?-img_20160930_162323.jpg

    Now look at the part number on Nextie's site.

    "[NXT27XM36] PREMIUM 36mm Width Carbon Fiber 27.5" / 650B Mountain Bike Clincher Rim [Tubeless Compatible]"

    [NXT27XM36] PREMIUM 36mm Width Carbon Fiber 27.5" / 650B Mountain Bike Clincher Rim [Tubeless Compatible]

    I'll let you guys draw your own conclusions.

    I agree that all the rims come from one or so manufacturer and that some are standard off the shelf pieces sold by multiple sites. But sellers do also have rims they own the molds for made to their own design. The asym rims from Carbonbicycle are an example. They designed those from input from here. I saw profiles before they started having them built. I'm sure LB and Nextie have some designs of their own also.

    Eyeing up a set of rims for a 27.5+ the 36mm ID rims from carbonbicycle.cc are about the width I'm after. I've had light bicycle sets before everyone been happy with carbonbicycle.cc ?

    I'd be truly surprised if carbonbicycle rims didn't come from the exact same facility as virtually every chinese-made carbon rim. My guess is that the same guy who did the layups to make a Nextie rim on Monday swapped out molds and did CarbonBicycle rims on Tuesday.

    Probably. I care about price and quality and both companies have produced. It takes a month for them to get to your door but if you plan ahead its not bad.

    I honestly don't even think there are any special molds for any one company (although I'm not dismissing the possibility). If you look at the rims...there is nothing really separating them from one another. Pretty much all the producers of the carbon rims are in Xiamen. The trading companies set up an office there also. All they need to do is go from manufacturer to manufacturer to source their rims.

    If they can meet a minimum, there is a good chance the manufacturer will make a mold for you. Now if the manufacturer still owns that mold...then they will produce for whoever asks. These molds are pretty expensive to make...so it's very unlikely that a two or three man operation will be able to afford to buy their own molds.

    It's possible for companies like LB and Nextie grew enough to afford their owns molds...at the same time there is nothing really proprietary about their rims either. So I really don't see why they would want to spend money on their own molds. Lol...even if they did have their own molds and shapes...there is a good chance whatever shape they come up with will be copied in no time flat.

    The only other thing I can really see possibly differentiating the rim from one another is the layup and resin used...but how the heck are you going to prove that your did indeed use a different layup and resins. I mean...we don't have real proof that the big brand guys do it...besides them telling us that they do.

    The asymmetrical carbon rim seems to be the next up and comer...and if they are you'll see them all over Alibaba in the net few months.

    These are nothing more than my thoughts...so it should not be taken any other way.

    ^^^I completely agree with you.
    And I will give an example, I got my rims from Peter, at the time only him had the rims in the configuration that I wanted, asymmetric, 26mm ID, and 3.5mm walls. Couple of months later Nextie or LB, don't recall witch one or if both, had the exact same rim, with the exact same spec's and weight. Coincidence? Not in my opinion...

    These are nothing more than my thoughts...so it should not be taken any other way.
    I'm not dismissing any of what you say, but I seem to remember reading somewhere that at least LB (maybe others like Nox?) does in fact pay to develop and protect their own molds that aren't generic. Some supposition about the slow adoption of asym rims by others. I have no idea whether they can/do enforce it. I agree there isn't much difference in brands or specs.
    I agree that layup configuration is hard to prove. Though naive, I want to believe that companies who are trying to build a real brand beyond an eBay store are legit in their claims. Nextie is pretty vocal about offering a choice of layup angles: 30 and 60, or 45. I'm not sure how you could/would prove that, but it seems like a lot of effort to fake and the cost to reputation is a big gamble if you're caught.
    When I see an Easton ec90 bar on eBay, shipped from china for $30 with poor english in the posting and no effort toward legitimacy, I expect that to be a lie. I have more faith in the truth from a company with employees and a "brand".

    Shrug. my opinion is just some dude talking. I want to feel good about my rims so I'm guilty of confirmation bias. For all I know my rims were bought in a lot of 500 from a truckbed in a dark corner of a chinese alley and are no better than the shadiest ad on Alibaba.com and made by some 12 year old high on drugs.

    Pretty much all of what goes on here is pretty much all speculation.

    I'm not dismissing businesses have their own molds at all. I mean that is probably the best way of protecting their own designs. I just don't think it makes that much financial sense in putting in tens of thousands on molds for designs that can be potentially copied real fast.

    No name carbon bars are something I will never use. Rims, frames, saddles...I'll run...but no way I'll take a chance on a handlebar.

    I broke the only carbon bar I've ever owned. a real, honest, authentic Easton ec90sl riser bar, purchased from Competitive Cyclist. I don't know what caused the failure, but it crumpled and bent where the 'riser' levels off to the 'grip part' when I was bunny-hopping in my driveway setting up a fork. could have been something I did, but it failed, nonetheless.
    I replaced it with a RaceFace Turbine alloy bar.
    I'm not really that jazzed about *ANY* carbon handlebar. It's definitely not logical, but carbon frames are triangles that reinforce themselves, carbon wheels are circles with spoke tension for reinforcement.
    Somehow, a very long lever clamped in a narrow vice with reasonably sharp edges and forces applied to the outermost ends just seems.....nope.

    shrug. I'm crazy. I'd probably not have carbon wheels if I could get alloy to perform as well, but it only took one ride to realized that metal can't come close. I figure they're all made in the same building, and there's enough of them out there that my chances of defective failure is low, and a broken rim is probably not catastrophic and crash-inducing. I got lucky with the handlebar.

    Your logic is irrefutable. That's why I'd have zero problems with the failure cause the repeat probability is de minimis.. Call Easton and get another. It'll be like my Easton carbon bars and most of the others-repeatedly beat on and no problems.ie. the SC frame video.

    I like the fact that each of these small marketers isn't building their own rims. One manufacturer means better quality for all is more likely.

    Good find but those two rims are way different.
    The match is with CB rims. Like this one. EXCEPT the weight is 20g lighter. And that means less carbon layers. So consider that and your use.

    You're not going to find much variation between the rims. Maybe some minor differnces in shape and depth. All these guys are in one town. So if they are a trading comapny...there is a good chance that they are sourcing rims from the same factories...and there should be multiple factries to choose from.

    As for layup...if you contact the seller...they should offer you a choce of a "AM" or "Enduro" layup. With the Enduro being the heavier version.

    When I ordered my rims...they asked what layup, type of drilling, and even Presta or Schrader.

    I ordered the AM layup, UD matte finish, with standard drilling (since I wasn't sure what hubs I was going with), and Presta valve holes on all rims.

    ~$160 seems to be the standard pricing for rims coming straight out of China.

    Right. I posted the pics just to make the "clone" point...sites nearly identical...didn't mean the rims were. Sorry for confusion.

    That EIE 39mm id asym rim is 460g +/- 15g for 165 + 50 shipping for 2.
    So 445g(requested) rims for 380 shipped.

    No one thinks you're hyping anything. We just want to see an i39 rim option in 27.5. You say you ordered some, so what's the harm in sharing the source so we can see our options?

    Good find, nice to have more potential sources, but those are 29er i39. RSVR6 is saying he found a source for i39 27.5 rims.
    I'm looking for: 27.5 rims with 39 or 40mm internal width, asym, with "slanted" 6 degree drilling or shaped/reinforced spoke holes.

    Yeh I was trying to stay true to this thread being in the 29er Components but I did find this 27.5 w i39 in the Premium section of Nextie...maybe ask them about hole angles. http://www.nextie.net/premium-mountain-plus-NXT27XA45

    you guys are daring trying some of the no name rims. if those crack on a fast downhill it could seriously hurt. light bicycle at least tests and improves their products and at $400-500 a pair is still cheap for carbon. the $100 ebay rims just seem risky

    If you're looking for a group willing to take on risk...well mtbikers are towards the top of the list, obviously.
    Of course you should spec all your equipment for the type of terrain and speed you'll be riding.

    Anyone care to offer some insight on the advantages of the eyelet style rims vs a rounder profile for plus size tires, 2.8-3.0"? I am looking at these two from XMcarbon as I have had good dealings in the past with Peter.

    HR742C 2015 NEW design 27.5er mtb carbon hookless rim 42mm wide - Xiamen Carbon Speed Sport Goods Co.,Ltd

    HR740C 650B carbon mtb rim hookless mtb 27.5er rim 40mm wide - Xiamen Carbon Speed Sport Goods Co.,Ltd

    Obviously there is a difference of 2mm in width, 60g in weight, and 5mm in depth but why the eyelet design? I am building up a set of 27.5 plus wheels for my GF. She is 115lbs. I know this is the 29er forum, but this thread is the best resource for chinese rims.

    Ask him to clarify the use of 'eyelet'. I don't think those rims have metal eyelets. That seems to refer to the bump and offset spoke hole asym design. Wider is better so I'd go with it and request rims at the minus end of the weight allowance for your gf.

    Just a quick update on my carbonbicycle 35/30 standard shape rims. Road the entire season on them, loving them every ride. My first carbon rims and custom built wheels (using DT350 hubs and DT comp spokes). Held true extremely well. Had a few rock hits, and other than surface scuffs, no damage or problems. So far so good! Would buy again.

    Hi Matt,

    There are a lot of trading companies in China which often try to copy the more popular brands. This is another example of a company trying to clone our site which we spent many years building from scratch so it's unfortunate. It's easy to make a profile that looks similar, but this has very little to do with the performance of the product in comparison to having sound manufacturing processes. I see their logo is eerily similar to a certain high end brand as well...

    China produces tens of thousands of carbon rims each month, trust me the same guy isn't making all of the rims or layup schedules It's true that many of the companies are trading companies which definitely adds to the confusion and misinformation. There are also a lot of different manufacturers which may or may not sell to the public. For Light Bicycle, we don't sell our rims through trading companies, but I'm sure you will find a lot of rims that will look similar at a glance.

    Hi Inertia Man, We're building am asymmetrical 27.5 rim with a 40mm internal width right now, it's in the final testing phase and will be released at some point in late November. We can do custom drilling, but our standard is 6 degrees. For the spoke hole test, these are testing out to 400 kg/f before it can pull through (highest spoke tension used on wheels is about 130kg/f) so this is not going to be a concern for these.

    Has anyone purchased/used the Nextie NXT29WC38 rim? (32mm ID, asym)

    I would like to know if the spoke holes are drilled "straight" (perpendicular to the rim surface) or drilled +/- 6 degree to position the nipple in line with the spoke direction to hub flange?

    Sent the question direct to Nextie but have not been getting a response.

    If LB had a 29er version of their EN733 it would be a good fit for one of my new wheelsets, but no sign that LB is doing this anytime soon.

    Six degrees seems to be a pretty standard drilling. That's what I got when I asked them (Apex) for whatever is their normal drilling since I wasn't sure about the hubs I was going to use. Since alot of the companies don't produce the rim till you order...if you ask...they can usually do a custom drilling for you.

    I'm not particularly concerned about the actual angle ( 6deg, 5 deg, whatever . . . so long as its not zero). All the early LB rims were straight drilled. I used many of those rims, and I found the non-angled holes to be undesirable. Unlike thin alloy rims which allow the nipple to pivot and align with the spoke (especially if eyelet'ed), the carbon rims are substantially thicker and effectively hold the nipple on-axis w/ the hole, with little/no ability to pivot. So I am unwilling to use straight-drilled holes anymore if I have other alternatives. Just wish there was some clarity in the spec from Nextie (or response to my inquiry).

    I would interpret this "no response" as straight drilling, unless someone here actually got a rim from them drilled in an angle.

    I don't think it's something you can ask them to do. It's done by a machine, so if they had it, the rims would probably come like that already. Unless you want them to do it with a hand drill

    You also have to wonder if they just drill a hole in an angle, or also rim the surface of the nipple seat in an angle (inside the rim).

    I asked Nextie before I bought my first set and they said they drill the spoke holes on a 6 degree angle.

    FWIW: I got a set of rims from CB that were specified to be drilled at 6 deg. On other rims I've gotten angled drilling was fairly obvious due to the staggered big holes in the rim bed. On the CB rims I could not see any evidence of angled drilling in the stagger of either the holes in the rim beds or the nipple holes themselves. I had to put close fitting rod through the nipple hole to see that they were indeed drilled at an angle, and identify which holes to use for each side of the hub.
    Do the math.

    I received a response last night to my second inquiry, and they confirmed that the NXT27XA45 is drilled at +/-6 degrees.

    As you're noting, when drilled at an angle, it leaves a non-perpendicular seating surface for the nipple inside. With most nipples, this is not a concern, since they have a curved/spherical lip which can seat off-axis. Some Sapim nipples specifically promote this shape. Useful as that is, though, it isn't helpful if the rim thickness effectively prevents the nipple from "tilting". Hence my focus on angled drilling.

    I've also used rims w/ angled drilling but w/o staggered holes. I found that dropping a spoke & nipple into a hole and seating it will usually show a subtle but noticeable "slant" to one side or the other. No doubt that wheels have been built by inattentive builders who don't bother to determine that orientation . . . and one thing worse than straight holes is -6 degree hole with a +6 degree spoke in it!

    Looking for 30mm external width, asymmetrical xc rim. I would like as light as possible. I have had great luck with Light Bicycle, but there wasn't as much choice 4 years ago as now. Other choices seem to be: Xia Men Yuan, CarbonFan, ebay (hulk), Nextie, Yishun, EIE and ACE. I'm sure some of these are made in the same factory and re-branded. Any other been there, done that experiences? TIA

    That's going to give you a 24mm iw, which will match with heavy casing tires aimed more at dh speeds where lightest means cracked.
    Otherwise you should consider 30mm inner width a minimum. Like the CB asyms of 29, 34 or 39.
    When it says in the specs + or - 15g you can use the note to request rims at the minus end.
    [NEW] Asymmetric Mountain bike 27.5er&29er AM hookless rim 40mm wide - Asymmetric Rim - Carbonfan|Carbon Rim|Carbon Wheel|Carbon Bicycle|Carbon Frame|Carbon Bike Part|Mountain bike

    You can match that with tires with a rounded profile like Bontrager XR Teams.

    ^^^ I'm running CB's 29mm inner width asymmetric rims with XR3 and 4. The rims weighed 418gm against their 400 +/-15gm spec, close enough within the uncertainty of the scales. Wheelset is 1630gm, but of course that will depend on hubs and spokes. Running tubeless with Kapton tape rim strip.
    Do the math.

    If you've been happy with your LB rims, it's not a bad idea to stick with them since you know what you'll be getting. As a return customer, they will offer you a discount too. Ive been very happy with the 3 sets I've owned.

    I have been very happy with my LB 30mm external width rims (~385g), running IKON 2.2 and 2.35 for years and happy with the handling. Minor crack on one after many years and tons of miles. I am looking to build a similar or lighter wheel using an asymmetric rim. LB's lightest offering is either 28mm or 34mm ext. width, and $249/$269 plus shipping. The other companies mentioned are lighter and cheaper. I am still asking if anyone has good experience with any of these companies, especially if you bought a similar rim.

    I see. Food for thought thought though. It probably doesn't matter for your situation considering what you're after, but those lighter rims probably have a lower weight capacity too. That, and you can request the rims be in the - xx weight range when you order. You may have to wait longer, but they will usually do it IME. The price is probably higher since the name is more well known, but it's worth seeing what your return customer discount will get you. I guess I should be more open minded, but I tend to stick with the more well known names if I'm going Chinese carbon, i.e. Nextie, LB. I think they have more to lose on the "word of mouth" gauge if things go wrong.

    I've been running 460 gram 29" 30 mm internal width rims with 3.5mm thick sidewalls, 32 spokes. I have been racing enduro on this wheelset on a 4" travel bike. Now I know that is far from ideal, but is what I currently own (a new bike is in the works). I weigh 175 ret to ride.
    My concern is that I've cracked 2 of these rear hoops in almost 2 years. I'm wondering if it is because the rear suspension packs in after multiple hits and feels like a hard tail. The bike runs out of suspension and the rim gives in? Although when it happens there are often multiple destroyed rims at the event, carbon and aluminum, and on longer travel bikes. I'm beginning to wonder if I'd be better off with aluminum on the rear wheel of the new bike build, or if 140mm will be more forgiving and less prone to destroying rear rims.
    Any thoughts on this?

    I am far from an expert but after seeing things like Santa Cruz testing their aluminum vs carbon frames I would continue to stick with Carbon all day over aluminum for strength. Carbon is a damn amazingly strong material and not that much more expensive for these wider rims than their aluminum counterparts.

    Anyone have first-hand experience w/ spoke calculations for the Nextie 32mm internal asym 29er rim NXT29WC38? They spec the ERD at 579mm, but I'm measuring at 584mm.

    Nextie has an FAQ/definition for ERD which indicates the measurement is taken not at the internal rim surface, but at the nipple base: What is ERD (Effective Rim Diameter)?

    My measurement method used two exactly 250mm cutoff spokes threaded/glued to have threaded tip flush to slot (ie, includes nipple base thickness) so in theory should match Nextie's number.

    If Nextie is saying one thing (includes nipple base) but doing another (measuring to internal rim wall) then the 584m versus 579mm would be reasonably well explained by the nipple base thickness.

    Anyway, it would be very useful if anyone had similar experiences with this specific rim and can provide insight on how their length choices turned out after the build was done. Without additional data, I'll probably use 582 or 581 for calculations. Just want to avoid the case of almost-too-long-spokes (which happened with one of my LB builds years ago).

    Nextie has an FAQ/definition for ERD which indicates the measurement is taken not at the internal rim surface, but at the nipple base: What is ERD (Effective Rim Diameter)?

    My measurement method used two exactly 250mm cutoff spokes threaded/glued to have threaded tip flush to slot (ie, includes nipple base thickness) so in theory should match Nextie's number.

    If Nextie is saying one thing (includes nipple base) but doing another (measuring to internal rim wall) then the 584m versus 579mm would be reasonably well explained by the nipple base thickness.

    Anyway, it would be very useful if anyone had similar experiences with this specific rim and can provide insight on how their length choices turned out after the build was done. Without additional data, I'll probably use 582 or 581 for calculations. Just want to avoid the case of almost-too-long-spokes (which happened with one of my LB builds years ago).
    If you measure right, and it sounds like you did, then it doesn't matter what people who don't know what they are doing or talking about say, even in the unfortunate case that those people happen to have made your rim.

    Oh, but they didn't make my rim, they just sold it, right?

    In general I agree with you, I have direct measurement so I should proceed with confidence, and not sweat the Nextie specs. But if someone chimed in w/ similar experience and a post-build photo of spoke position in nipple base, I can proceed with even more confidence. I'm also used to working w/ higher precision materials so ignoring OEM specs isn't exactly in my DNA.

    Also, take several measures on both rims, you should get small variations but nothing that will interfere on your calculations.
    Also, as meltingfeather mentioned, it doesn't matter what other people measured, as long as you took precaution measuring your rims, you should go by your measures.

    I did 4 measurements on each rim at 45 degree intervals, all were within the +/- 0.5mm error that I'd guess is inherent in my informal "tooling".

    Nothing to do with your rims, but the ERD listed for my chinese carbon rims was 579mm, then when they arrived I took a couple of measurements and the mean value I arrived was slightly over 583mm.
    So, don't give it too much importance to the discrepancy.

    FWIW, now that I've received the rims, I can confirm that they are indeed angle drilled. I have no means to distinguish 6 degrees versus 5 or 7 degrees, but its pretty obvious when one places a spoke & nipple in alternating holes that there is significant orientation bias toward one side or the other.

    Maybe I am getting this wrong, but on this page the text and diagram contradict each other.

    The diagram shows ERD at the rim surface, the text says to add the nipple heads (4mm).

    I am looking to build up a new 29" set of XC race wheels. Certainly interested in keeping the wheels light as possible, but willing to add some weight to get a rim with a little more internal width, thinking an internal width of 24-28.

    Anyone have any specific rims that they think are a good compromise between weight and internal width for XC racing?

    i have 30mm external Nexties on my XC race rig, I wouldn't go any fatter. That's just me, but wider starts to get significantly heavier.

    Part of the choice involves the tires you'll run. Bontrager XR1 Team 2.2s have a very rounded profile that works great with 30mm inner width rims. I use that combo and won't use anything skinnier with that tire or the 2.35 XR2-4.

    Hi,
    Have you ordered from EIE ? I'm looking for some feedback.

For the spoke hole test, these are testing out to 400 kg/f before it can pull through (highest spoke tension used on wheels is about 130kg/f) so this is not going to be a concern for these.
    Will these be available in 29?

    I haven't ordered from them.
    29er 45mm wide rim all mountain Enduro strong bicycle carbon rim, tubeless ready, “mid fat bike” rim
    That rim is a copy of a CB rim. I've ordered from them with good response and the quality has been problem free.
    [NEW] Asymmetric Mountain bike 29er AM&DH hookless rim 45mm wide - Asymmetric Rim - Carbonfan|Carbon Rim|Carbon Wheel|Carbon Bicycle|Carbon Frame|Carbon Bike Part|Mountain bike
    The difference appears to be a weight of 460 + or - 15 for the EIE vs 480 + or - for the CB.
    Both are 39mm inner.
    And the listed price is $30 more for the CB. I think they may price match if you email them with the listing.
    You can request a rim at the lower end of the range.

    I eventually decided to try out EIE carbon so I ordered a pair of 650b 29mm inner width assymetric rims. I just received them today and so far they look good with the custom color code I asked for the decals (which are not stickers but under the clearcoat I think).(Cheap) Chinese Carbon Rims?-eie.jpg

    I just bought a C'd Scalpel that came with ENVE Twenty9 XC rims. They've got an IW of 17.9 and are currently shod in 2.1" Racing Ralphs.

    To make this bike a little more trail-oriented, I'd like to move to 2.4" tires. Does this rim support 2.4" tires? If not, what's a good lightweight alternative? I was looking at XM's AS935C, but it seems a little heavy at 440g per.

    Really interested in the quality and durability of the EIE rims. Their prices and weights for an asymmetrical rim are impressive. Let's see how they hold up. Did you get the AM or the HD? Any weights? Thanks.

    I've run 30mm inners for my Trek carbon Superfly. You need to match that with a rounded profile tire. And then get the right pressure. Bontrager XR1 Team 2.2 or XR2 Team 2.35 have the rounded profile.

    This asym rim is 34mm inner for the 2.35 XR2 at 415g low range if you request it in the notes. 28 hole is fine.

    That seems very wide to me. I'm honestly not sure if the Scalpel dropouts will accommodate a 2.4 tire when it's allowed to stretch that far. How about this one from the same company?

    I got a mix, AM rim for the front at 360g and HD for the rear at 410g (I asked for the lowest weight range). They are being laced to Hope pro 4 hubs.

    How many mm. do you have between your chainstays where the side knobs line up?
    I'd push it with a Bontrager 2.35 XR2 Team if you have more than 76 mm.

    Interesting news- wonder if this will pressure NOX to lower prices.

    LB has teamed up with Nobl and is opening a US based facility. Prices are pretty good.

    I built a wheelset with 29mm inner Asy rims, I9 CL hubs with CX-Ray spokes- $1395

    I'm hoping that encourages *everyone* to step up their game. USA is a big market. It's a wise move, as long as it doesn't mean their $170 rims are now $250.

    No rim only right now. This is pre-ordering wheelsets. I would assume once it's actually open, the rim options will be there.
