2017. U28 refers to the rim shape. U-shaped and 28mm external width. Internally it sure looks a lot different than a standard rim. I have no problem saying it is designed specifically to be tubeless.

Editing here:  Looking at the 2016 and 2017 Tamland specs.  The 2016 state:  Weinmann Impulse TL Double Wall.  The 2017 specs add: U28.  Still, I want to see a claim from Weinmann as to what beyond the tape makes whatever rim in question a better rim for running tubeless above a regular rim.  There still seems to be nothing about the rim that makes it tubeless beyond the tape, and sticker:  http://www.weinmanntek.com/Products/DISC/U28.htm


Well yes my bike is a 2016. Yes they are tubeless rims and marked as such. Mine per say doesn't have tape on them but instead has a plastic sealed sleeve is what I would call it around the rim. I know I have the front rim tubeless with tires that aren't to be tubeless the Clement xplor mso 40mm. I did the Stans shake that I read about here. The rear just had too many small leaks for it to work though.

The makers of the U28 rim seem to make no claim about it being tubeless in anyway:  http://www.weinmanntek.com/Products/DISC/U28.htm  

It was probably Raleigh who wanted it marketed as tubeless.  Look, they say, it's taped, you can convert it to tubeless if you want.  Again, there seems to be no bead barb like on AC or WTB rims.  The hook looks like any other.  I am not trying to be dificult here.  Maybe the rim you have in hand (and the one on the 2016 Tamland) is different than pictured on the Weinmann site.  It would be great if further evidence could be produced to settle this.  I have nothing more to offer.

For sure my rim is different that Shoota's as mine just has tubeless ready sticker around the valve stem and no U28 sticker.

I'll see if I can get a good picture of the inside of the rim. It'll probably be tough because of the angle but I'll try.

Ok I just pulled the tire off and trust me this is not just a normal road rim taped up. There are channels for the bead to sit in and the rim is hooked more to hold the bead in place. These wheels are definitely designed to be tubeless.

Crud.  I did not want you to pull a tire off for the sake of this discussion.  But thanks.  

This is the kind of stuff I have been going on:  Here is a good image of a tubeless specific yet non-UST rim design.  It is an AC rim.  Working your way up from the center I think that it is easy to see the bead barb.  That first little lip.  Go out further and you get to the very defined hook that captures the tire bead.

The Weinmann images don't reveal (to me at least) any such barb and it is hard to tell but the hook seems a bit more open.  http://www.weinmanntek.com/Products/DISC/XM280.htm


WTB rims that have their TubelessCS design show a barb like AC:

Stuff I have already said.  I guess that I am just trying to be clear.

Yep. My rims look basically the exact same as the AC and WTB you just posted. The Weinmann you linked is certainly not the Impulse, trust me. In fact, I don't even see the Impulse on their page. It's not uncommon for an oem to make a product that is not available to the general public.

One of the links I posted earlier was for the U28, and it was hard for me to see anything tubeless about it.  

http://www.weinmanntek.com/Products/DISC/U28.htm  

Here is the Impulse which I thought you were at first talking about:  http://www.weinmanntek.com/Products/RACE/Impulse.htm

The Weinmann site can be frustrating for sure.  

Nonetheless, sounds like the rims you have in hand are designed to be tubeless, not just due to tape, with barb and hook.  Now that we are done here....ride in confidence.

Oh good find! I don't know why I couldn't find that, maybe cuz I'm on mobile? Anyway, that U28 looks TR to me. The beads sure do snap into place like a tubeless setup should. Ride on [smile]

I have the 2016 Weinman Impulse TL and they came taped from the factory and have tubeless ready painted on the rim. When I first got them  in 2016 Weinman had this model on their site now they don't. One of the differences between the new web model and older 2016 model is the inner width which is right at 21mm on 2016 rims. The current ones are 18mm. 

With that said I have had 100% success mounting 6 different tubeless ready tires without issues on these rims.
The Schwalbe G-1's were difficult but mounted anyway. I tried mounting non-tubeless tires on these and they both failed. Clement USh35 and Clement mso 40 Air retention issues, unreliable.

Raleigh started using these in 2016 prior ones were not TL. IN 2017 they went to the U28
I also think there is more to it than just tape and labeling. 
Mine developed a hop in the rear wheel after ~3000 miles and even the LBS coudn't get it out and by the way they Fu*%ed up my wheel dish truing it. Won't be going back there again.

Anyway I have since ordered a set of AC TCX wheels and they are coming in soon. I will try and post a side by side and maybe even do some measurements. I hope I like the AC's as much or more than the Impulses.

Why wouldn't Raleigh warranty that hop in your wheel? Thanks for that clarification as I was starting to get paranoid that my wheels weren't tubeless ready and yes I have the same tl wheels.

I didn't consider calling them. After a year and a half and over 3000 miles and being trued up multiple times I think it's on me not them. They started life perfectly round. No biggie I got my moneys worth out of them.

So, shoota, as it turns out, we were both pretty much correct about the rims we each had in mind.  I took another look at the U28 link and thought once again that there was nothing about the rim picture or cut away that showed anything tubeless in design.  Yet the rims before you looked like the AC and WTB.  So, not expecting anything to happen, I emailed Weinmann. But what do you know....  I think this is a pretty clear clarification that the U28 I was talking about (and probably the Impulse that I found the link to) is in fact not tubeless in design, while the rims that you shoota have before you, are in fact tubeless in design.  

My email to Weinmann is at the bottom and their reply at top:

Hi Chris,
 
That's not true because the U28 is for normal use, however, we have another model name "U28 TL" it for tubeless use. The U28 TL is not on the website, now we are building a new website and will be online before end of this year.

People are telling me that this rim, the U28, is specifically made to run tubeless.  
 
 
Please inform me as to what makes this a tubeless rim.
 
Thanks,

Wow excellent sleuthing Chris! I guess we were both right haha. I kinda had a sneaking suspicion that it may have been one of those situations where it was an OEM only product to begin with. Makes sense now.

So you guys have completely lost me now. So if I am reading this right they make a U28 for normal use and a tubeless U28 TL that Raleigh has the sticker on it or is Raleigh just putting the tubeless sticker on the regular model. Does this hold true for the RL model that my 2016 Tamland is that has the tubeless ready sticker on it. Lost @ Newburg PA.

It sounds like there is a U28, on the Weinmann site, that is not tubeless.  It also sounds like there is a U28 TL, not yet on the site but will be by the end of year, that is tubeless by design (it has more than just tape and a sticker, probably at least a barb to help slip the tire in place, hold it there, and help prevent burbing).  

But heck no, I am not making any further statements above that, especially about a different rim I don't have in front of me, made by a company with an out of date website.

Do you think I should email Jason to get an answer on my rim?

I am just going to make a guess here:  My guess is that your case is just like shoota's:  There is a non-tubeless rim.  This rim now has a tubeless version the TL.  This TL version is not yet on the webesite.

I got tired of reading all the replies so sorry if you already figured this out. [smile] The U28 (and 32 for mtb) were designed by Raleigh with Weinmann for a one year exclusive. After that, Weinmann was free to sell them to their customers. That's most likely why they are not on the website. Asian supplier websites are not updated that often and it sounds like Jason mentioned that in his reply. Very nice kid by the way and I was happy to see he responded. The U28TL seals up really well but its also a very tight fit. It takes some work with some tire brands (Schwalbe of course is one of them) but they hold really well once set up. Best of luck! Oh and you cant go wrong with American Classic either, personally my favorite wheels.

That is what I kind of figured out as my 2016 Tamland has TL on the wheel and then Shoota's wheel is the U 28 that is completely different than mine but also tubeless.

Yup, Impulse TL was the first and also designed for the cross category. Then, because wider is better, the U28 was developed. A little too wide for cross if you are trying to keep your tires around 33-ish but perfect for gravel. [thumb]

Ok after my first ever gravel race the Pony Express 120(opted  for the 75 miler) I can really say my Tamland 1 performed much better than I expected. After lots of questions and help from everybody here on the forum I opted for the Kenda Flintridge Pro 40 mm tubeless. @ 200 lbs I ran 40 lbs rear and 35 lbs. front. I really didn't know what to expect at this ride/race. No I wasn't racing it as I had some major medical issues before the ride with massive collarbone pain starting back in May and then 3-4 weeks before the ride they gave me a steroid shot in my neck where they messed up and hit a nerve in my arm which was too sore to ride. Training then was a measly 28 mile training ride the Monday before the ride. Back to the Tamland at the beginning of the ride I was picking my lines but as the race progress I was less worried on the line I was looking for. The only sketchy part was at 62 miles which they brought up at the riders meeting but I din't catch that. Most walked their bikes down there but I locked up both brakes and slid down probably 50-75 feet. It might have been less than that but it sure seemed farther. I don't know about your guys but I name my bikes. I call her Tammy Lane as kind of a take off of the bike's name. She came through with flying colors. I might get another set of lighter wheels but am satisfied completely with my Raleigh. All yeah I feel in love with gravel racing during this ride/race. Let the fun begin.

Thanks again for everybody's help/suggestions/encouragement on this forum.

Zman
