All I can say is soapy water and over-inflation might do the trick. For particularly stubborn tyres - I unfortunately was forced to take them into my bike store. There they used soapy water and overinflated with a compressor. Perhaps this is something I could have done at home, but I must admit I was too scared to overinflate too much, while they are experts and know what the tyre / tube can handle. These were 2.25" MTB tyres that just wouldn't seat evenly despite dozens of attempts.

Thank you - I need to wear this watch a lot more!

LOL!

Yes, these are PRIZM Road. I saw a few posts later about a warranty replacement being offered for this problem, but I never got it myself.

Is this on a road bike? What pressure do you normally run and how wide are your tyres?

@@TheIndianCyclist yeah road. I use 30c with 65-70 psi pressure.

From reports on the FB Trek Domane group, there are some distributors who are still unbelievably unaware of this problem!

@@TheIndianCyclist I am personally fuming over it and if they are a Trek approved dealer, they 'should' make themselves aware of such issues and Trek should ensure they are. These are not cheap bikes... some take the position that Trek bikes are very good, but they are overpriced. I don't expect this kind of piss-poor problem when you spend this kind of money. I have contacted Trek and we will see what happens.

@@johnchilton3975 I agree with all your points - not what should happen especially around the very tech that is a "feature" of the bike. I made a video all my Trek woes here: ua-cam.com/video/WjbYrNT2h2I/v-deo.htmlsi=lmyAEGm-WAWTYWSA (though I will add that _now_, after fixing stuff, I am very happy with the bike)

@@TheIndianCyclist Forgive my ignorance here - what is the significance of Rev1 to Rev 5??

It's the revision number of the wedge that is part of the problem - you should be able to see it in my video. My bike came with Rev 1 and when replaced with Rev 2, the problem was solved for me. However, Rev 2 did not fix the problem for many others, most of them reported that Rev 4 fixed it for them, but there were a couple of posts that even mentioned a Rev 5 being available.

Had a relative bring them in from Germany.

The whole point of the video is to say you should do exactly that :)

👍how did you attach the chain to the bar?

@@TheIndianCyclist i attach it to the bar with chains own pins , or you can use nut and screws

Am so gald it helped. Seating from the side opposite the valve is generally recommended while seating tyres too, though some people prefer doing the exact opposite!

Thank you so much! This is actually the first 'super thanks' I've received ... I appreciate it and will never forget it!

Interesting! Must say I have not heard of this being a problem. I can see how high temperatures could cause more evaporation losses and drying out of the sealant though. 32c under 50 psi does seem rather low though, especially with tubes - surprised you're not getting snakebites all the time! How/why so low?

It's been awhile since I've used this computer, but I believe you're correct, that would be "ascent" for the ride.

Very interesting that in your case the removable valve core is clearly a disadvantage, and I can see how a loose core would be problematic, especially with a pump that you have to screw on. For home use at least, can't you get a pump that you don't have to screw on? As for the valve core tool - I managed to get my hands on one and it is so much better than using pliers! Do try to find it online, it's relatively cheap and worth it if you have to deal with this problem often. Here's the one I use and it works well. www.bike-components.de/en/Schwalbe/Valve-Tool-Schrader-Sclaverand-Presta-p82265/ All the best!

LOL. I would love to agree with you completely about people sticking to tubeless, but I do believe there are some road bikers who genuinely benefit from it. I would wager they're in the minority though!

Wahoo Fitness app - I added a link in the description, but here it is: play.google.com/store/apps/details?id=com.wahoofitness.fitness it would definitely work with an S21.

Thanks Ketan! Sealant is messy and that's why I always leave it to the mechs if I have a chance. Did you try tubeless too?

@@TheIndianCyclist no, I have never tried tubeless yet. It’s like the electric cars feeling - I never feel comfortable without a spare tube at hand! 😅

Fingers crossed! I know many are fine with Rev 1 too, but if you are fine with Rev 1 for awhile, say a year, I wonder if it will be fine forever!

@@TheIndianCyclist I got my bike last night and I think it’s rev 1 actually. It’s not creaking now. But I’ll see what happens. I am 91kg so I guess it might be some problems

About the same weight here. Keep a close eye on the seat height with the height markings at the back, even if not creaking. Gradual slips over time and/or slips of 5 mm are easy to miss.

@@TheIndianCyclist had another issue. Both front and back wheel is loosing air. So going back to store. I mean it’s probably just something easy. But with new bike I rather have them fix it

Were they set up tubeless? If they used bontrager sealant, take that junk out right away and start with Silca to give tubeless a fair shot. Just made a video on tubeless too: ua-cam.com/video/Mhwz0UsXZ3c/v-deo.html

Thank you so much for the kind words - all the best for your cycling journey!

I also forgot to mention that I weigh 220lbs and wear the tires out haven’t had to replace a set due to too many punctures.

28c Cinturato Velo is actually what I was using at the front after I had to abandon my 32c stock Bontrager R3s (the one with too large a hole caused by my botched plug attempt). This I did add Silca to, but the tyre never got a single puncture for me to test out the sealant! (the rear R3 did puncture and Silca didn't help - possibly because it hadn't been topped up and dried out). I'm now on 35mm Cinturatos - decided to just run tubes because I'm so happy with their puncture protection. Good to know how 28c worked and 25c was poor - does seem from comments that 28c is the minimum size that would be viable for tubeless.

When I first went to tubeless I used Bontrager r3s the tires were leaking air through the sidewalls

R3s are really such nonsense tyres - loads of complaints about them across different functional areas, from poor durability to delamination. They came stock with my Domane, but must say I did not have that problem with them - no problems with the initial tubeless setup (which was done by the store prior to bike delivery).

All the great routes are outside the city, but I really shouldn't complain, Pune is far more blessed in this department than most cities in India. Am slowly increasing the amount I ride on weekdays, rides are now typically between 18 & 25 miles, but not waking up early enough limits your options as you have to deal with way too much traffic if you start a ride anytime after 8 or perhaps even 7 AM. With my new tyres (35 mm Cinturato Velo) which I just switched to, I'm feeling a lot better on the bike and hopefully set for longer weekend rides that should be around 50 miles. I agree, all things considered I need to ride this bike a lot more and take it on longer rides.

Am glad people recongize this as fair coverage of both sides of tubeless!

I was concerned with the video turning out so long, but am now glad I didn't edit it down - thank you for your kind words, much appreciated!

Glad you think so, thank you :)

Too negative? The man did clearly say some people have good experiences with tubeless and explained its advantages over tubes.

@bluegem72 I believe he is referring to my personal experience with tubeless, not my review. I agree that it really has been very negative! @user-so8qg8ys5b it sounds like the opposite in your case, an experience that is way too positive! Especially being able to set up easily with a basic pump with non tlr, vintage rims. Interesting theory about basic, heavy tyres making things easier and more robust. What sealant did you use - how many punctures do you think it fixed on your setup?

Thanks for providing a good experience anecdote here. I won't say you've been lucky, more like you are nailing [sic] the tubeless use case :D how many punctures do you reckon the system has fixed for you? Have you been using the Silca replenisher on schedule - no issues with it drying out?

@@TheIndianCyclist yeah my sealant has yet to dry out, I just top up on the sealant every 2-3 months depending on how many punctures I've had, but topping up is usually not that much sealant. When I was getting punctures, my tires were reaching the end of its life (I had been using the same tires for about 8 months of consistent use at that point). I reckon it sealed close to 3-4 punctures, mostly small, but it was able to close one quite sizeable one as well. Silca tends to work best for most people, so I'd recommend going with that if other sealant brands have been failing you. Hope this helps!

I quickly moved to silica after I found the initial sealant failing, but it didn't work for the couple of punctures I had after the switch. At least the first one it should have sealed, the second could have been because there wasn't enough fresh sealant. If & when I try again, I'll be sure to start with Silca!

I really think great tyres could solve 90% of the issues!

Can't disagree. On the Domane SL5, bad tyres and bad sealant give you a terrible first experience with tubeless. ua-cam.com/video/WjbYrNT2h2I/v-deo.html

Skill and know how will make a difference for sure, but the tech issues like sealants' inability to seal at high pressure and sealant drying out and clumping are bigger challenges IMHO.

Agreed! I think quite a few riders don't realize how easy it can be to fix a flat with tubes as well.

Yes, ultimately the higher pressure can make a significant difference to the efficacy of the system.
