I first posed this question in the Raleigh Tamland thread because there seemed to be a lot of discussion about the Weinmann U28 TL rims, but it was suggested that "Gravel Wheels" might get a better response (makes sense).  So here goes:

I'm considering buying a 2017 Tamland 2 (or one of the other Raleigh adventure bikes).  Although the intent is to use the bike primarily for gravel/mixed surface rides, there will be times when I will use the bike for 100% road rides.  My question is about the Weinmann U28 TL rims that are spec'd on all of the Raleigh adventure bikes.  Has anyone mounted 28mm road tires on these rims?  If so, tubed or tubeless?  Any issues running typical road tire pressure?  I can't find any information on the Weinmann website regarding minimum/maximum tire width and pressure for these rims.  I believe these are ~22mm ID.

Thanks.

You probably could do it. Keep in mind that most 28's would measure 30+mm on a 22mm ID rim. Thus, you're likely going to be in the 50-60 psi range max if you go tubeless. Any higher is likely going to be a rough ride and possibly stress the rim more than it was designed for.

I converted their slightly smaller sibling, the Impulse TL to tubeless and have 28mm Schwalbe One Tubeless tires on there. Those tires spent over a year on 22mm ID American Classics without a single issue, so I knew they would work well. One thing to note is the Weinmann rims came with one thin layer of tape, something similar to the Scotch 8898. I added 3 layers of 8896 on top to build up the rim a little better and also keep from blowing out the spoke holes at higher pressures. So far, so good. It wasn't a super tight tire fit, so building up the rim bed with a couple layers of tape is probably a good idea no matter what.

Whether you do tubed or tubeless, you will probably want to add some more rim tape if you plan on any pressure above 50 psi.

That's not a tubeless rim, and I'd recommend staying with tubes.  The bed of a rim is shaped in such a way that allows a tire to be mounted tubeless, and those are not.  Bad things can happen when your tires burp or blow off.  

Tubeless profile looks like this-

Your rim is 22mm internal.  A 28c tire is really pushing things on that, and again, I don't think it's the greatest idea.  I think you'd be fine with 32's, though.  The rim above works with 28's.

Raleigh and Weinmann said the "TL" designation means they are tubeless compatible. My "TL" Weinmann Impulse rims have a bead shelf type profile and work fine with road tires.

I looked up the rim and could not find the "TL" version, but if that exists, then I stand corrected.

My Raleigh 2016 Tamland 1 has a tubeless rim on it. It came with Clement mso 40 mm tires on it which weren't tubeless. I managed to get the front tubeless but not the back. I since have switched to the Kenda Flintridge Pro 40 mm tubeless.

I think the  mix up is these rims were made specific for Raleigh so there isn't much info out there on them.

I had the same issue with the front tire.  The rear sealed fine and has been running tubeless for 600+ miles.  I always had problems with the front and ended up replacing it with a Maxxis Rambler (free from the DK!).  No issues, other than a slight wobble at one place on the rim.  It hasn't affected my riding any.

We had opposite things happen. I was able to get my front sealed and not my back as it just  had lots of little leaks with the Clement MSO tires. I replaced both tires on my bike with Tubeless Kenda Flintridge Pro 40 mm because of locals recommendations for the Pony Express in Kansas. I did the 75 miler. They might be more bullet proof but for sure are slowing rolling than the MSO's Did everybody get a free tire from Maxis Rambler or did you win it in a drawing? What ride did you do at DK and how did your ride go?

Thanks

I ended up getting a puncture on the Rampart Rager here in CO on the front tire.  I realized that all of the sealant had dried up.  After I got home & cleaned everything up - the puncture still wouldn't seal - that's when I just changed the tire.

I did the DK half-pint 100 and had a great ride.  There's so much oxygen at that altitude!  On the other side of these hard-hitting valleys (not sure what you'd call them), there were at least 10 people changing tubes from pinch flats.  I was able to ride right past them.

The following day they had the awards ceremony & raffle.  It was basically - when we call your number come up & grab some merch.  I grabbed a nice Kask helmet for a friend.  When everything was said & done there was still a ton of Orange Seal kits and Maxxis tires.  So I grabbed a couple of each.

Now I'm thinking that I should change the rear tire as well.  I don't want to risk flatting & it not sealing.  That's time I'd rather spend riding.

Since you are from Colorado have you thought of doing the Crippler? That is on my to do list. I was at Leadville for 4 days the end of July to get elevation acclimated. I rode the bottom 1/2 of Pikes Peak(which is a story in itself) I heard lots of people had what they call tire burping at DK because of them trying to run too low of tire pressure. I will run some higher pressure and take some jarring as like you don't really care to be changing out flats when I rather be riding

Yep, it must have been people burping.  I probably run too high on pressure (40/45 or 38/43), but I don't really feel uncomfortable.  If the back end gets too squishy it really messes with my confidence.

The Crippler was certainly on my radar.  The high cost for late registration, combined with the fact that I couldn't find anyone to ride with contributed to my lack of attendance.  I'll try again next year I suppose.

Well the Crippler is on my list for next year. I just came across it as I am the newbie to gravel riding/racing.
