WTB Frequency TCS i23 26" Rim: XC/Trail tubeless ready rim. Features WTB's Unbendium Bulge, a band of material on the sidewall that counters torsional, radial and lateral flex. I-Beam vertical wall support counters spoke loads and further...
Weaknesses: The paint, if you care about nicks and dings.
I've owned these rims for a over a year now and I don't any complaints with them. I ride a 6" AM bike and it is my only bike, so I use it for everything from XC style trails to DH shuttle runs. I run tubeless and use a trail tire or a DH tire depending on what kind of trail I am riding, I have never had issues mounting the tires, they mount up easily with a normal floor pump (as long as you are using a tubeless tire and enough sealant). The 23mm ID is great for squaring out the tire's profile and delivering better performance from any tire regardless of brand or intended use. I have had to true the rear wheel once and it does have one small ding on the side wall of the rim, but it doesn't effect the performance of the rim. Bottom line if you are looking for a reasonably priced, strong, light rim then you might want to give these a try.

Strengths: Light, well build and strong.
This was bought to replace a 6 month old ztr flow laced with sapim laser spokes..
i weight 240 lbs and have never been happier.
these are lighter than the flow. the bead sits in deeper and more secure than the flow. havent had a pinch flat once for over 40 hours of riding and pair with 4 different tires.
stiff enough for me to take it across large rocks and roots at 35km/h clocked with my gps with lots of small drops and high speed braking corners for 3 continuous rides and nothing bad came out of it. paired with a hope pro 2 evo 142 x 12 and a hope 20mm front and sapim laser spokes, brass nipples, total pair weight was 1.75kg with rim tape. these rims rock and like the previous reviewer, its a great product and hopefully only greater products can succeed it. technology sure makes such good rims viable and cost effective these days. they are awesome stuff and i do highly recommend it against the flows. its cheaper, lighter and i reckon stronger and can be pulled to higher tensions. the graphics are simple and nice but wish they had white rims. WTB, where did u out this rim from. its amazing!
I purchased these rims as part of a custom built wheelset from Universal cycles (pretty legit service, actually). The front is laced to a Hope hub (to cut costs a bit) and the rear is laced to a Chris King HD. After 7 years of being broke, cheap, or a sad combination of both, I figured it was high time I spend the money on something that (hopefully) works like a champ and may last the better part of a decade.
There aren't too many options for a 23mm inner width tubeless ready rim and I really, really wanted a 23mm rim. I read a number of individuals complaining about how soft Stan's hoops were and Mavic's offering, while bombproof, weighed only slightly less than a two-handed broadsword. There were extremely few reviews of the i23 so I figured I would be doing the MTB community a service by trying a new-to-the-market product. Plus, I had a lot of faith in WTB. Worse comes to worse, I can trash the rims and build the hubs up with something with a better history.
I've had total of 4 rides on them so far. Three of those rides were in Fruita and the last ride was at Buffalo Creek in Colorado.
-The first thing I thought when I hit the trail was how stiff these rims are. I feel almost no flex and it inspires me to push a little harder in the corners. I felt very connected to the trail.
-I'm pretty rough on my stuff. It was pretty important the rims stay true throughout a ride. After a lot of rock gardens, a couple drops, and countless poorly picked lines, they still hold straight and true (a bit redundant?). It's important to note that one drop sent me over bars and somersaulted the bike with me. Were I too rate the durability only on these rims they would definitely receive 5 Chilis. Look forward to putting these rims through more geological warfare.
-Weight is simply a numbers game. Universal Cycles lists these rims as ~200 gr lighter per rim than Mavic EX823s. That is quite a bit of gramage to shave off of rolling stock. It also ever so slightly helps lofting the front over those larger trail obstacles.
-Unfortunately, due to a number of variables out of my control, I had a shop put on both tires while they checked initial spoke tension. This means I can't personally comment on how well the tires go on. The tech said the tires went on easy and sealed up immediately using a compressor. I can, however, say that the rim/tire interface has provided an awesome seal. I have not experienced a single burp since riding these rims. Tire choice does play a role in this aspect, so, to be fair, I may just be exceedingly lucky by having the two perfect tires for these rims.
Overall, I'm extremely satisfied with my purchase. I feel confident that they'll last and remain stiff for the next couple years. Putting them through the paces of Fruita and coming out unscathed definitely boosts my opinion of them. If you want your stuff to be tough and durable then have a look. They cost about 40 dollars less than Mavic's renowned EX823s and, at this point, perform on par, if not better than the Mavics.
Similar Products Used: First tubeless ready wheelset I've owned. Brief experience (read: riding my friends bikes around the block) with other UST/tubeless rims. Owned and ridden countless mediocre, tube-specific rims and a few good tube-specific rims.
Bike Setup: Specialized Pitch. My do-all bike built for me to have fun anywhere on the mountain. Tires are 2.35 Nevegal Stik-E tubed version up front and Geax AKA 2.2 (non TNT) in the back, all with Stan's Sealant and tape.
Anybody have luck mounting Continental Race King 29ers to the WTB Frequency i23? I'm not sure if the tires I have are UST or not and I'm having a heck of a time trying to mount them with a floor pump and a Co2 pump.
I'm also new to tubeless, would it help if I used a soapy solution.

Apologies if this has already been asked but.....
What's the deal with the WTB I23 rim? Would these be an upgrade, downgrade, or even swap from my current P35's? Anybody with any real world ride time on these?
Thanks!Read More »
Built up a pair for myself over the weekend.
Picked up the i23's from Arts Cyclery (excellent service) and had my LBS cut and roll me some Sapim Force spokes. I used a set of Laserdisc Lite hubs that I already had.
Wheels built up super easy and smooth.

Can you help me hunt up a solid source for this wheelset? My requirements: either the i19 or i23 rim, and a great rear hub (doesn't have to be Hadley or King, but need plenty of engagement, so no X9 or XT); I don't care so much about the front hub (and I have a King hub I can replace it wi ...
