They did a Christmas sale, I ordered a set of 29i standard wheels with Bitex hubs for 640$ inkl shipping. Should come at about 1550g. So far haven't heard anything regarding shipping, but I expect it to take some more time if the sets are build to order.
 
Does BTLOS run sales? The wheelset with shipping is ~$1200, seems reasonable for 1400g. Building them myself is basically the same price unless I hunt for hubs on PB and/or sub $350 rims.
I've only been watching their website, off and on for the past six months or so........ the best sale I've seen was back in October/November when they offered free shipping. I bought my first wheelset from them for $800 ish after shipping with DT350 hubs. That was including the premium layup (better warranty) and Sophy also suggested the 160kg layup (not listed on the website) when I asked about commuting with them.

I had an issue with Rene Herse and Teravail tires not cooperating with the BTLOS hookless rim........I sent some pictures and asked some questions since all the specs were within the approved ranges for the wheel and tire manufacturers. Sophy offered 20% off which is about the same as free shipping and covering the credit card/PayPal fee. I gladly accepted and just ordered a second set with a hooked rim and will save the other wheelset for bikepacking on more gnarly terrain with heavier casing tires.

Were those gravel rims?

The second set was the WGX35A. I would have preferred a 25mm internal measurement, but 22 was the only width in a hooked rim. I asked about the possibility of a wider hooked rim or any upcoming sales or free shipping promotions…….no dice. So I went ahead and ordered the wheelset a week ago.

My first set was a 30mm all mountain/enduro setup since I thought that would allow me to run anything from a 29x2.2 up to 29x2.5. That didn’t go as planned, and I learned a little bit about supple casings on hookless rims.

Now I have the ability to run pretty much any tire I want between those two sets of wheels.

I guess I never heard about this issue wrt MTB tires and wheelsets. Some quick googling seems mostly talk related to CX or gravel/road.

Bonty has 120 tpi casings in their team issue line, pretty supple and on the very light end for MTB by many folks. Even Maxxis Aspen or Rekon Race…

After some research, it seems that the wider rim, hookless design, and 38 psi, it wasn’t going to work in tubeless format for me. The Teravail Sparwood was even easier to blow off the rim. I just wish tire manufacturers were more transparent about exactly what widths and rim types they recommend for each tire. Lesson learned on my part, I’ll just have different wheelsets for each.

I’m 280 currently……..so that definitely played into it also.
The biggest thing I found out during my research was that most of the 29x2.2 tires showed 30-55 psi on the sidewalls. I found quite a few people that run those tires quite bit lower than the recommended pressure. I had assumed that 30 was the minimum, so my big ass needed more pressure to compensate for the load.
I’m running 29x2.4 Schwalbe Hurricanes (tubed) right now and will run skinnier Marathons once my hooked wheels show up.
 
I finally received my WM-i27AL wheelset on 1/13/23! They were ordered on 11/30/22. That puts lead time around 6 weeks, which seems a little longer than other reports on this thread. I imagine BTLOS gets significantly busier during November and December. Based on the tracking number updates, the box stuck around in limbo for 1.5 weeks before being received in California. I assume this is customs-related and a busy holiday queue. Ultimately, not a big deal since it's off-season for me, but something to consider if you're ordering from them with the intent to use them for an upcoming event or trip.

Initial first impressions are very positive. The wheelset was packaged securely and included valves, tape, and spare spokes. I opted for the 3k matte finish and it's seriously beautiful. It's subtle at a distance and goes along with the partially-visible layup on my Epic Evo frame. I visually inspected all surfaces and holes for imperfections and I'm happy to report there's nothing to report. The parting line on the rim channel is flush and all drilled holes look clean. Total weight is 1,285 g (front: 689 g & rear: 596 g). I'm running with DT350s and I was surprised at how quiet they are even with a 54t ratchet. I pulled off the freehub body (so easy!) and it's well-packed with grease. I expect it to get a little louder as the grease fades. So yeah, I'm impressed with the quality and appearance of this wheelset.

My only minor complaint is the addition of a drain hole by the valve stem hole. I didn't know this was included. I don't believe it's mentioned anywhere on BTLOS' site. If I order another wheelset, I'll request that it is not included.

I timed my LBS suspension service to go along with a new wheelset install, so everything should be ready to go by the end of this week. And based on the non-winter weather we're having in Michigan, I should be able to get in a ride or two before the snow finally decides to stay. I'll report back with ride impressions when I can.

Well, for XC racing may be the 267mm rim, but for trail and all-around, probably the 30. Would not do 28 and straight pull, but would be ok if it was 28 and crossing, and not x-rays either.

Coming from XM1700s which according the DT are around 1890g. Want to light and reasonably strong wheelset to run 2.4 XC'ish/trail tires like Rekons or Bonty XR4/XR3 on my SB115. Northeast rider here, so plenty of rocks and roots, 190# kitted up.
This is the same rim choice conundrum I'm facing.

I'm going to lace them to Onyx hubs so am really tempted to go for the 27AL to claw back some grams. The Premium AM i30 has the same max weight limit as the 27AL.

I'm ~78kg (guess 85kg kitted up) and ride a mix of mostly XC with some grade 4 and 5 downs. I ride pretty cautiously on the super steep stuff, but I'd like to have wheels I have faith to ride everyday, or down anything I have the confidence to ride.

I'm thinking the 27AL because I tend to put on my spare wheels with DHR tyres when I know I'm spending the majority of my time riding the steep stuff.

My current DTs are 28h, 3 cross, straight pull… seems like if you go CL, then it’s straight pull only option with 350s from BTLOS. I know you can get j-bend models.

I assume the 27 vs 30 mm rationale is more than just the width… more to do with intended usage/weight of wheelset?

Why no rays?

Yeah, IDK why they only offer those in straight pull, seeing as I have CL DT hubs that are J.

J is just the standard that you can pick up at almost any shop anywhere. So that's why you build your wheelset with them. Straight are a lot harder to get ahold of so if you ever have an issue (stuff happens, like sticks, etc.) it becomes less worth it in the long run.

Yeah, 27 vs 30. 30i is pretty wide and good for enduro-sized tires around 2.4-2.5. But even when the casings are thinner, they are still slower tires than something a little skinnier. There's an incredible range of tires, so there are thinner casing ones that are fatter that roll better, and there are thicker casing skinnier tires that don't roll as well, but all things equal, I wouldn't want to race XC on it. 27 also isn't much smaller, not even 5mm, so you aren't losing out much at the 27mm internal size and you may have more versatility if your plan was for some racing and smaller tires. I wouldn't want to run 2.2-ish tires on the 30i.

On the x-rays, they are expensive for no good reason, similar to above, you'd have more trouble finding one at a shop if you had to, aero benefits don't apply to mtb, etc. Sapim is full of BS when it comes to the x-rays. They aren't horrible or anything. I use Sapims, but the x-rays are 100% about looks. The Sapim lasers are the exact same spoke, also cold forged...just in a round butted shape. The biggest reason would be, since these are going on a carbon fiber wheelset, I'd recommend butted spokes. You'll get a little better compliance that way. It's not huge, but again, upselling to x-rays is just spending more for no good reason, unless you are doing it for looks and then, well, sometimes we do want our rides to look a certain way. Nothing wrong with that.

When I was researching wheel build advice, I was recommended bladed spokes as they're easier to tension without winding up as they're a)easier to hold, and b)easier to see if they did begin to twist. What's the best way to get around those two things with straight gauge spokes?

I was stuck between these two choices too. I went with i27. Ultimately, I think they're both great choices. Your deciding factor should be your desired tire width.

In my opinion-
2.4" and below: i27
2.4" and above: i30

Using proper spoke prep compounds, this just isn't a "thing" to worry about.
