    WTB Frequency i23 AM wheelset: alternative to Flow rims

    I just completed a 26er AM wheelset with the new WTB Frequency i23 rims (UST/TLR profile), Wheelsmith DB 14 spokes, and CK ISO hubs for a customer in Toronto. Total wheelset rotating weight: 1,850g. I am completely impressed by the quality of these new rims: 469g, 120kgf max. spoke tension, very nice design details. As I finished the build process, the wheels had the feel of having developed high strength, and built up very true.

    Next i23 wheelset presently underway is a 29er set for a customer in Eugene.

    I'd say they are definitely an alternative to the Flow. Given they have a true UST rim profile and they are eyeleted some would say they may even be an improvement (though my Charger Expert wheels with BST rims work just fine with UST spec beads).

    I'll be interested to see how the new Pancenti TL28's compare as well.

    With the Frequency rims, WTB eliminated eyelets for directionally drilled and radiused spoke nipple holes. They are getting even better durability in this manner.

    Does the "23" refer to the internal width of these rims, or outer width? (WTB's website is lacking in critical information)

    25 mm wide tape such as Stans is recommended for the i23.

    just picked up a set of CK hubs laced to 29er wtb frequency i19's pretty darn light. however i didn't get to weigh in grams but under 4lbs for the set w/o cassette.

    29er AM Single Speed WTB i23 Wheelset!

    I just completed a 29er AM Single Speed wheelset with the new WTB Frequency i23 rims (UST/TLR profile), Wheelsmith DB 14 spokes, DT Swiss 350 front hub and CK ISO SS rear hub for a customer in Eugene. Total wheelset rotating weight: 1,990g. I am completely impressed by the quality of these new rims: 503g, 120kgf max. spoke tension, very nice design details. As I finished the build process, the wheels had the feel of having developed high strength, and built up very true.

    2,000 grams ain't light! WTB seems to have done a nice job with their recent rim upgrades, took them a while. But please, NEVER stop making the DD!

    WTB TCS Details

    Here's a link to a WTB web page showing rim cross section UST details: TCS. The bead hook & lock design provides a more secure hold on the tire bead. The center well "on-ramp" has room for the tire beads when mounting a tire on the rim, and geometry to help the bead to move from the well to the bead lock. Just makes mounting a little easier, depending on the actual shape of the tire bead.

    I designed this single speed AM wheelset for a customer with a riding weight of 225-230 pounds, it needs adequate strength to meet his requirements.

    It's pretty light for a 29er AM wheelset with CK hubs. An identical wheelset with Flows would have weighed approx. 100g more.

    Where did you purchase new rims WTB (FREQUENCY i23 26)?
    I could not find them on sale in any online store.
    What is the technology of "4D Drilling"? About her writing WTB in the specification to the rim.

    Any WTB dealer can sell WTB rims, and I am one of probably many dealers. I may have been lucky enough to build the first ones commercially. The Dealer Locator portion of WTB's website has a message saying it is temporarily unavailable. The International Distributors webpage directory is working. The WTB online store web pages don't appear to have been updated yet with the new rims. The rims should be showing up on the online stores soon, as they have carried all of the WTB products in the past.

    The 4D drilling is angled drilling with each hole pointed directly towards the hub flange hole where the spoke is intended to go. This minimizes the bending stress on the spoke and nipple at the rim from otherwise less accurate alignment.

    How do these compare to the Lazer TCS All Mountain Race rims?
    What about max spoke tension?

    Good question.

    In online stores you can buy both Frequency and last season WTB Laser TCS.
    The 19mminner width are both mentioned at 385g.

    Seems the new design dropped eyelets for the 4d drilling.

    Did you have the change to build with both? what is your opinion.

    Just bought a set of Laser TCS XC 32h, and are getting ready to be built with DT Revolutions 2.0-1.5-2.0 and WTB Laserdisc hubs (reusing the hubs from an old wheelset)

    WTB said that they got better rim durability results using the 4D spoke hole drilling technology as compared with their previous eyeletted rims, think of this as a further refinement in their rim design. The rims have the same maximum spoke tension as the previous Laser TCS models: 120 kgf. I do like building with the Frequency rims better than the Laser TCS rims and have gotten even better results.

    I'm planning on building at wheelset with these rims in 29 inch with either Hope Pro 2 or XTR M988 hubs. Does anyone know the spoke length for these setups? All parts are yet to be ordered, so I can't measure anything myself. No info on ERD or anything on the WTB site.

    I measured the ERD for the two 29er i23 rims I ordered at 599 mm each. It is always best to actually measure your rims before calculating spoke length, especially until the consistency of the ERD is established for new rim models. Hub measurements are more standardized, and manufacturer's measurements can usually be trusted.

    What is ERD (to calculate the length of the spokes) you used to WTB Frequency I-23 a diameter of 26 "? On the manufacturer's website could not find the data.

    I looked up somewhere it was 535 for the 26".
    I think i saw it in a catalog.
    But its better to measure it for real.

    Width...

    As above, I assume the inner rim width is 23mm.

    What about the outer width?

    So the question will be, how are these rims going to compare to the Flows - being just as wide and about 70g lighter per rim.

    Time will hopefully tell.

    My biggest question will be the this rims ability to hook up with non-UST tires. For example, I really like Kenda non-UST tires and they mount up perfectly with Stans.

    Can anyone comment on the bead-tire interface differs between the WTB and Stan's?

    Frequency i23 26er ERD

    I measured the ERD for the two 26er i23 rims I ordered at 537 mm each. It is always best to actually measure your rims before calculating spoke length, especially until the consistency of the ERD is established for new rim models. Hub measurements are more standardized, and manufacturer's measurements can usually be trusted.

    Read through the whole thread for more info on these rims.

    I replaced a worn out non-UST 2.35 Kenda Nevegal on my rear wheel(Stan's Flow rim) with a WTB 2.3 TCS Weirwolf. I mounted it with a floor pump and it sealed up much quicker than the Kenda. I think the WTB Weirwolf stopped leaking air after one day. Seems to have comparable traction in dry, rocky conditions as the Kenda. I haven't rolled it yet, so the bead hookup seems to be fine. The sidewall does say something like, "Warning: read the owners manual at wtb.com before mounting", but I couldn't find any info about the Weirwolf at the WTB website. I'm currently running it at 35 lbs, and I weigh about 235 lbs with gear.

    The WTB does however look much narrower than the 2.35 Kenda Nevagal, and I think it is much heavier to boot.

    Would you ever build wheels with straight gauge spokes for heavier riders? Why or why not?

    Oh frekken finally starts making some UST beaded rims at 21 or 23 mm inner width.............Oh, and that aren't boat anchors (that's directed at you Mavic).

    Although, I really have to question the 385 gr weight listed. My experience with WTB and list weights is add 20% to get the real number. Anyone put just the rim on a scale? (26 inch)

    I really don't mind the tape as long as the rim profile and bead hook are UST type. I like my UST and TR tires, but not the std tires ran tubeless.

    If all this turns out to be a decent rim for $75, I will finally be having my 2nd Lefty wheel built up.

    Well, one thing about mavic rims is they're pretty bomb proof. Never the lightest however. Surprised they haven't jumped in on the tubeless ready band wagon yet like WTB and DT

    IIRC, Mavic did the whole UST thing and has tried to license that tech so companies can put UST on the label. So, I'm not sure if Mavic would do a tubeless ready setup or not.

    It seems as if Mavic stopped doing anything after the put out the 819 and 823 rims. Those rims don't appear to have changed in the 4 yrs I have been riding mtb. They appear to have worked a lot in their wheelsets.

    I would have been ok with an 821 rim.

    Mavics weights always seem to be without the eyelet insert thing you have to use with their 8 series rims. So, add 50 to listed weight.

    The wheels pictured in the first post by 4slomo, are my wheels built by 4slomo. I met him through a mutual other hobby of hi-fi audio. A friend of mine who is a biking nut had Steve build him a set of wheels and liked the experience so I followed suit. The whole affair was top notch. He is a pleasure to deal with. Ok..enough with the sales... (I am not affiliated, just happy customer)

    The wheels have yet to be mounted. This is my first set of "hi-end" wheels. Meant for my Giant Trance X2 (with mucho upgrades). I like to push my limits. I am no pro rider, hardly, but I did ride BMX as a kid and like to be aggressive and take drops from time to time, so I wanted an AM set of wheels.

    The website lists weight for the i23 TCS rim at 475g. Above guys keep saying 455g... so uh what is it?

    Obviously there will be variation on rim to rim but is it 20g?

    Are the rims priced better than Stans?

    There is some confusion, in part because the 2012 Catalog lists the i23 rim weights as 455g/26" and 470g/29", and the website lists the i23 rim weights as 475g/26" and 530g/29". I back calculated a weight of 503g/29" as noted in Post #12.

    The i23 26er 475g rim weight listed on the WTB website may be a typo.

    I can back calculate the rim weight from the total wheelset weight. I weighed the 26er wheelset I built at 1,850g. The calculated weight is 1,862g. The difference in the two weights is 12g, which can be allocated equally to the two rims, so the average weight per rim is 475 - 12/2 = 469g.

    If I back calculate the rim weight for the front wheel separately, on my scale the front wheel weighed 840g and the calculated wheel weight is 846g, The difference for the front is 6g. 475 - 6/2 = 472g for the front rim.

    The rear wheel weighed 1,000g and the calculated weight is 1,016g. The difference for the rear is 16g. 475 - 16/2 = 467g for the rear rim.

    Averaging the two calculated weights: Half of (472 + 467) is an average weight of 469.5g for a 26er i23 rim.

    WTB Frequency i23 rim website retail prices: $75/26" and $80/29".
    Stans Flow rim website retail prices: $90/26" and $93/29".
    Lower prices for the the rims can be found at other online stores.

    Obviously there will be variation on rim to rim but is it 20g?

    Are the rims priced better than Stans?

    Thanks for the info 4slomo. I've been a big fan of the LaserDisc Trail rims. They've taken a beating on my bike here on the Shore.

    I was going to build up some Flow's but now I am pretty sure I'll go for the i23.

    Do they come fairly straight and build up easy? I've only built 8 wheels so I am still a beginner in the fine art of wheel building.

    Has anyone had any real problems with the Flows? I've just had some laced up and have never ridden tubeless before.

    I have 4 sets of flow rims one for each of my bikes. Never had any issue with them. The key is to find tires that work best.

    Maybe I'm misinformed, but that's the reason I never went with the Flow set up, tires. I just want to grab my TR or UST tire, put in on and go. I don't want to have to worry about getting it to seal, burping etc.

    I'm hoping with these new i23 rims supposedly with a UST bead, that I can just put a little tape on, sealant and go.

    LOL, yeah, I think they do, but they dont want to pay Mavic so they call them Tubeless, or Grid (Spec) or some other catching marketing name.

    When I want tough over weight, I go full UST( or equiv)

    Are the Flows fragile in a ghetto tubeless set-up? Does the lack of tube take away an important buffer between the rim and destruction?

    I have had a lot of different tires on the flows and never had a problem getting any of them to seat or seal at the bead interface. UST, TLR, regular tires, they all locked in with no problems. As for durability, I would say that because of the really low profile of the rim you get fewer rim strikes when tubeless and fewer pinch flats when running tubes. So yes they are durable.

    Why fewer rim strikes with a low profile? I'm worried that running at a lower pressure (one of the things tubeless allows you to do) will mean that the rims are "hitting" rocks more often and harder.

    Hey guys,

    This thread is to discuss the i23 rims. Please try to help me keep it on topic and more helpful to those interested in the i23 rims, by discussing the Flow rims in a different thread. Thanks!

    Woops, apologies. Although this is also information that may sway someone towards or away from the i23 (also, the Flow is mentioned in the subject).

    Not much to talk about regarding the WTB i23 since it's not even out yet. Oops I just noticed Universal Cycles has them in stock now.

    I'd like to hear feedback on these rims from anyone using them on a 29er.

    Flows - 29"

    29" rims - that is what I was comparing.

    Flows with most any tire thus far (TLR or non-TLR) have been quite easy to set up.

    I 29" Flows as I recall look like they come in at about 525g and I've yet to kill one within a reasonable amount of riding time. So, if I can get another rim, that is cheap, lighter, just as wide, and just as easy to mount tires to, I'd consider a change.

    Now, if we are only talking a few grams, like 20g or so, I'll stick with the Flows. In terms of both east of setup and performance, they really have been great.

    Hi.
    Wanted to ask.
    Is it possible to UST, TLR tire put on the rim WTB Frequency with a hand pump rather than floor pump, no compressor?I ask because on my Mavic UST rim, UST tire is worn easily with a hand pump, without the use of magic.
    Many manufacturers talk about the compatibility of its UST rims, but reading the forum it appears that users are experiencing difficulties with the production of tires, they are often in general not possible without a strong push to put the air compressor that provides a powerful floor pump.
    I offer my apologies for the error in the text. I'm from Russia, to communicate with you using google translate.
    I hope you understand me.

    mounting tires

    Hi zg2tn9,

    I just received a response from WTB today. WTB has a video showing Jason Moeschler and Mark Weir, two racers, mounting WTB Bronson 2.3 AM TCS tires on Laser TCS All Mountain Race rims, which have the identical dimensions as the Frequency i23 rims, using a Topeak Mountain Morph hand pump.

    video mounting tire: WTB on Vimeo

    I've been wanting to upgrade my wheelset and this seems to be a good option. I'm new to this UST thing and wanted to ask if I can still use tube on a UST compliant rim?

    Also, crc has them but are listed as 2011.

    Yes, you can use a tube on a UST rim.

    I've built up quite a few wheels now with both the i19 and the i23 in 26 and 29. Much easier to build than Stan's, primarily due to the fact that there's no real binding to speak of between the nipple and the rim. Quality on the rim is excellent. I've got a pair on the way that I'll be building for a personal set. I am eager to get these going to see what long term durability is going to be.

    Good post 4slomo. We've had the same discussion here in the bike shop that the i23 is a potential Flow killer.

    I just built up a i23 29er wheelset. Will test it out once my Charbon Frame comes in this week and I finish building it up. I've ridden a set of i19 which were great.

    They have only made one iteration of the i23 to my knowledge. It just started shipping in November or so. Unless you're not in the US, why not pick one up from a local dealer? $71 is pretty easy for most local shops to price match.

    Not from US and will be buying a custom built wheelset with hope pro 2 and crc is a bargain for the set.

    joints

    Here you go. Same rim, different angles. This particular rim went together very well. No hopping or funkiness at the joint. Good stuff.

    This is probably a dumb question but do I need a tape on these rims to run tubed/tubeless? If not needed, will adding a tape has its advantages/disadvantages?

    Check out the second picture in post #1. See the spoke holes drilled in the rim? Those need to be sealed up by tape to keep the air in the tire/rim from leaking out through the spoke holes. An additional advantage of tubeless rim tape is if your tire fits too loosely on the rim, you can add an additional layer of tape to help the tire bead seal against the rim.

    To run tubed, you can use either a rim strip, or use rim tape.

    Here's some more inside/outside pictures, however, my macro lens function isn't as good, the joint is between the two central spoke holes, and have minimal gap, well finished:

    Like this thread and love the 4D drilling.

    Wonder if they will make one of these with a little more burl? Like an I25 or so.

    4slomo: How strong do you think this rim is compared to a 721? Besides being like 100 grams lighter.

    When built up, the i23 rims feel stronger than flow rims. I'm not as sure of a comparison with a DT-S EX500 rim, as to which might be a stronger build. I'm sure the ENVE AM rim is stronger than an i23 rim.

    I don't recall seeing WTB recently building rims wider than a 23mm internal width, so it could be surprising if they came out with one.

    Here's an anecdotal testament to the WTB rim design: I built a custom wheelset last year using WTB Laserdisc XC rims (immediate predecessor model to the i19 rim, with eyelets and no beadlock) for a customer. He already had a burlier wheelset for AM, and wanted something lighter for more everyday riding. He liked how the XC wheelset performed so much, that he rode it continually for his favorite ride, which he ends with him taking a 6 foot jump to flat. When he popped an alloy nipple head off of a spoke, he emailed me and we concluded that he might be overriding his wheelset. I told him that his wheelset wasn't designed for such large jumps, and it would be best for the wheelset if he didn't take that jump on his ride. I also told him that if he wanted, we could rebuild it with stronger rims to meet those requirements for his favorite ride, or he could just keep riding his XC wheelset until he trashed the rims, and then rebuild it. So far, he's decided to keep riding and taking the jump.

    Well the build for my 721's came out very strong. Too bad I like to run with low pressure then don't notice when I've lost some air. I'll be replacing the 721 in the rear. I do much admire the angled spoke drilling seen on I23 and 800 series Mavic.

    Considering the price point of the 721 and that likely I'll be replacing rims every few years I've got some thinking to do.

    Cheers!

    4slomo, is there any possibility to safely remove stickers completeley or partially ? I like the rims, but I started to really hate that black-white-red color scheme. Because it, almost literally, everywhere.

    Hi nameresu,

    I had a customer take off WTB Frequency i23 stickers from both sides of his rims on a custom i23 AM wheel build I did for him because he decided he wanted a more utilitarian look. He said he just peeled them off.

    I got these comments back from a customer riding his custom i23 29er wheels: "Am really liking the 29er wheelset you built for me! Did a rooty/rocky outback trail today on the Inbred SS. What a great ride!
    The bike is light and responsive. Very fun and easy despite the fact it was on a SS with a rigid carbon fork."

    4Slomo, Thanks for all posts. I'm In! Ordered Today

    Just ordered WTB 29er i23 set for Chris King Hubs (s.s. rear). 1st set of Kings for me. Love WTB products and been a few yrs since I needed something from them. I've been riding XT 26er set, and XT 29er set (SUPER noodley 9mm on FOX 120, but I love them). I can't wait to compare WTB Frequency i23 29er with my beloved Shimano 29er proprietary 19mm.

    XT 19mm 24 spoke
    WTB 23mm 32 spoke

    Should be interesting wheelsets to play around with. I can't wait.

    At least a few months. I know that these things just came out not that long ago, so obviously nobody has "years" on them.

    WTB changed the spec on the 29er rim on their site. It used to say 470g and now says 530g. Mine came in at 522g and 520g.

    If they are updating their website with real world weights, then perhaps I will start moving towards trusting WTB again.

    (Their tire weights were listed 100-200g off their rim weights were listed lighter too - it's the web, it's easy to update when you know the info is off and the production is higher, it's disingenuous )

    I got a hold of 2 26er rims the other week and on my "super-precise" harbor freight Scale-o-meter each rim came in at 471 grams.

    I have a honest question. My current Rim is a DT Swiss 5.1, and I think that the join is welded. Is there a difference in strength or durability or flexibility when it's joined like this or welded?

    As far as the joint is concerned, as long as the weld was prepared and laid correctly it should do a better job at keeping the rim round in that location. Lots of jumps and drops where there are high impact forces on wheels have a tendency to split or out of round the connection on pinned rims. This effect is more pronounced when the spokes are not up to proper tension allowing the rim to further deviate. When I rode BMX (street) before MTB the seams had to be welded otherwise I would need to build wheels all the time.

    In case anyone is interested I snagged a pair of i23's. As far as inflating is concerned I paired them to wtb weirwolf Tcs and could inflate them with my Blackburn mammoth pump.

    I'll let y'all now first impressions in a couple weeks. Having a set built up with some CK's and DT comps. We'll see how they hold up . . . my gut tells me this is going to be a solid wheel set.

    I've been trying to find out how these 26" I 23 frequency compare in strength to other well known rims with no luck. Looking at other options I came across something interesting.

    The one year only 2011 Laser Freeride TCS Rim: Products - WTB

    TCS, 23mm internal width and 540 grams.

    Compared to the I23 Frequency: Products - WTB

    TCS, 23mm internal width and 470 grams

    Is it possible they used the same extrusion and wall thickness for both rims and skipped the eyeletts in favor of 4D drilling? Could you shed that much weight by dropping the eyelets?
    I'm still left wondering.......I found a pair of Freeride TCS but if it is the same extrusion I would have better wheels with the Frequency I 23.

    If you think about it each eyelet probably weighs around 1-2 grams and the extra drilling maybe removes 1/2 a gram from each spoke hole. That works out to around 64-70 grams a wheel.
