[@leightonbohl1920]

Tip from an eighty year old cyclist. At the final stage of mounting the tyre, don’t use your fingers - ROLL the remaining edge of the tyre over the rim with the ball of your hand(s). Much more effective and less chance of pinching the inner tube. Cheers!

[@klein-concept]

Thanks so much. Will try it out next time 🤜🤛

[@ddahstan6876]

Just a Tip for novice riders-- When finished mounting your tube, please look in while pushing your tyre away from the rim to check for pinches, especially with wheels/tyres that are hard to remount (Ksyrium Elites and Continental Prix 5000 rings a bell?) Do it for both sides. Had I not checked my tyres for proper mounting, I would have to deal with pinch flats so regularly. This was a definitely great lesson for me after wondering why I got one flat after another after patching. If you see a pinch, pushing your tyre more inward most likely won't do anything... just carefully use your tyre lever, lift up that affected area slightly and push the inner tube towards the middle.

[@klein-concept]

Great tip. Thanks a lot for sharing it here 🤜🤛

I tend to ride faster on the road so the performance benefit and feel on-road makes more sense to me. Also, I tend to get more punctures with gravel so less expensive fixing butyl tubes than just going through TPU tubes which can't really be patched (in my experience).

[@jrl53]

I've always used butyl. The heavy, slow, thick, cheap stuff. Recently bought three RideNow 36g inner tubes to use as spares for a 375km race in Denmark (where you get punctures every 60km). I started the race with the butyls on. 30kms in, puncture in the front tire. I swiftly put the spare TPU one with no problems. Right as I get on the bike again, I thought it was leaking because of how supple and bouncy they felt compared to the chunks of hard rubber I was using before! They were not leaking! The inner tube held for the rest of the 350 km amazingly. Instant convert to TPU. Already bought 8 more and can't see a point where I go back. Even if I get a defective one, I'll just swap! Side note: for those 350km I did hear a rattle in my cockpit and I moved and tightened everything and still couldn't get rid of the rattle. Turns out it was the plastic valve of the inner tubes hitting my alu rim. That's why they come with some stickers to avoid this rattle. Now you know!

I'm 100% pro tubeless on my gravel bike, but I much prefer lightweight clinchers and TPU tubes on my road bike. You can pack like 2-4 spare TPU tubes in your saddle bag and it will still weigh less than 1 butyl tube. Plus clincher tires are easier to install and generally cost less (ex: GP 5000 clinchers vs tubeless ready tires).

For RIM brakes, the extremely light TPU tubes are not recommended, better stick with the 36 g TPU tubes or similar. I'm using cloth rim tape (Velox brand) for better thermal insulation, because the rims can get hot with rim brakes, especially in the front.

The way I do it is having two sets of wheels: 1. Training wheels with butyl inner tubes with inner tube sealant from Muc Off. Actually saved me from a flat just yesterday, during my 130km ride south of Berlin :D. MUCH easier to set up than tubeless (I also switched back from it), has the same benefits. The downside is probably having increased rolling resistance. 2. Wheelset with latex inner tubes, when I want to go fast and really feel the wind in my hair (I am bald btw). But TPU inner tubes are probably the way to go, if you are looking for a lightweight climbing steel bike! Looking forward to the result.

[@klein-concept]

Wait wait wait. Did you say inner tubes with tubeless sealant in there? 🤔 tell me more about that. How does this work?

[@CFAuugh]

@@klein-concept As far as I am aware, there are two products available which specifically have sealants for butyl inner tubes (some people reported it may work on latex inner tubes, haven't tried it out myself). 1. Muc-Off inner tube sealant. 2. Slime tube sealant. Auf Deutsch auch= Schlauchdichtmittel. These only works with inner tubes where you can take the core out the valve (all Schwalbe inner tubes have that, so that's what I use). You proceed to pump the sealant into the tube via the valve, put the core back in, pump up the tyre. Now you have a tube type tyre with sealant in it! I do stress though, this set up will probably have more rolling resistance (and the sealant weight!). But I do use it for long endurance and training rides. For go fast mode and doing climbs, I would definitely recommend latex or TPU tubes.

Btw I am considering converting from tubeless to TPU tubes on the only bike I´ve got with tubeless setup. It´s a good weather bike and it is not used as much as my other bikes. I basically have to clean the tires and rims every spring and renew the sealant. The sealant I use (Effetto Mariposa Végétalex) is much less messy than yours and very easy to clean out, but I´m just not convinced that it´s worth the faff. The main benefit I do see is that you avoid pinch flats. (Got disc brakes though.)

That can happen with any tube, I've had that exact thing happen with butyl tubes.

[@FT__Bicycling_____-sc7yv]

IMO the benefit of using tubes is that it's possible to use far less expensive tires. Conti Ultra Sport 2 are great tires and cost like $20-$25 each. And using these with TPU weighs basically the same as a GP5000 S TR with sealant. Personally - I prefer tubeless because of the ability to run lower pressure. They're more comfortable and that is a big deal. In my experience - if the tires seat ok on the rim (my current wheels/tires always easily do) then tubeless is easy. A flat would be annoying but I've worn through 3 or 4 tires so far with zero flats. I don't mind the tubeless setup. It's really not difficult. And not having a tube inside makes mounting the tire on the rim more relaxed

[@klein-concept]

I have also used tubeless successfully for a while. Liked the low tire pressures a lot so swapped all my bikes to milk. But it only needed one puncture to not seal and having to deal with the sticky mess for me to drop it and give tpu a try. Since then i m a happy tpu rider even tho sometimes it would be nice to have lower tire pressures.

I've had multiple Ridenow TPU leak, they were the older black valve stem type and I was initially putting it down to rim brake issues (across 2 sets of alloy and 1 set of carbon wheels) but then some would depressurize over a few hours and some over a longer period without ever being ridden on so the brake type had nothing to do with the issue.

That might be true. I think it depends on what your priority is out of the wheels. I m a casual rider so for me in this case convenience wins over potentially losing 2-3 watts in rolling resistance. If you re racing a lot those 2-3 watts might be worth the extra efforts.

@@tgc281 maybe give the Uno stem a try. It is cheap and if you swap out the screws for titanium it is around 100g. A more modern groupset might also help. I would think that they worked on improving the weight of the overall setup. Also have a look at the Drive 40V wheels. They are 1255g.

Im a big fan of tubeless setups but TPU inner tube might be the way to go for your bike - especially if your going for lightweight bike that is mostly riding clean road or is not your daily driver. I mostly ride gravel and endurance/road bikes. Sometimes riding my 32c road tires on some rough gravel and I had only one, easy to repair flat tire during 10K km period.

[@klein-concept]

Also been a big fan but after a recent cut from glass and the sealant nor a plug working, i decided to give this a try. Mainly because swapping a tube in would be so much cleaner and quicker. But also not saying no to some bonus gram savings 😂😂. But i agree for your setup with some offroad action i think tubeless is the ultimate solution that will be way more reliable on that terrain. 🤜🤛

[@tovinpoh]

tubless works better on MTB, but not as well on smaller width size road bike failures rate is too high and requires more frequent maintenance than the tubes clincher tyres. Normal tube tyres are easily replaces and repair also many cheap choices available. Cleaning of the sticky dried gum sealant is very time consuming, I rather spent these on a long hours riding than cleaning the sealant, and riding bicycles are suppose to make easy maintenance possible.

[@klein-concept]

I agree. It makes a lot of sense for MTB or even gravel but on a road tire maybe not 🤜🤛

I had to replace a tubeless setup in the front wheel with a butyl tube. It wasnt such a horrible gunky mess you just showed :D but I was/am on Stan's sealant. So far on my other road bike and ~2000 km - no punctures or issues ;). But i totally get how it can be messy.Also, I think, there are valve hole-plugs instead of rim tape, which might save some grams (maybe). Out of curiousity, is "Klein Concept" in reference to the bike Brand "Klein"? Also, is that a carbon, or steel fork on that bike?

I was also riding Stans for the most time. You re right i also dont remember it being so messy. The Silca stuff definitely is but maybe it also seals better. As it is crazy sticky 😂😂.

Good question now that you say it. For me the main reason was about the case of having a flat on a ride that the sealant doesnt seal. Like i had a couple weeks ago. Messing with the sealant on the side of the road is no fun. But lets see how the TPU tubes ride. Not excluding tubeless in general. Still have a couple bikes which are mostly set up tubeless.

Ridenow tubes: weight - 10 out of 10. Rolling 10 out of 10. Puncture resistance 0 out of 10. So, on your ride, how many time do you win with these tubes??

[@klein-concept]

Hehe thats what i heard as well and actually brought 10 extra tubes on my trip to Mallorca. Didnt need any actually. The ones i had installed lasted the whole 5 day trip with every day riding. Btw: do you think other TPUs are better or is it a problem of TPU in general?

[@rd22799]

The puncture resistance is zero when driving in less favorable circumstances. Rain, mud & sand. I think this is a problem with all these light inner tubes. If you do not want this you need “tractor” tires which kills the weight saving. Some things are just to good to be true. Such is life. These inner tubes are rather OK in very limited circumstances.

Well. I just installed a "gravel" TPU for 40-622. After letting the wheel sit for 3 minutes the TPU inner tube somewhat exploded, a big hole on the inner running surface (!), high pressure rim tape is new and 0 demage.

[@barrowsworm1226]

Really makes no sense to run tubes, TPU, or not, if performance is what one is after. Rolling resistance is considerably less with tubeless, and minor flats are also non-existent when running sealant. Fixing a flat is also, often way easier as it can be fixed with a plug, and no need to release the tire bead from the rim, or remove the wheel. Weight difference is not enough to justify the downsides, unless all cares about is looking at their bike on a scale.

[@klein-concept]

Dont get me wrong. I loved the convenience of tubeless when they work. But it was enough for me to experience them not working and a plug not being able to seal it. Putting a tube into a tubeless setup on the side of the road and riding with sticky hands from there was no fun and enough reason for me to give tpu a try.

Tubeless makes some sense for MTBs where you are riding very low pressures consistently and consistently taking large hits. Makes no sense at all for a road or most gravel bikes. Just a marketing scam designed to make you continually refill your tires with sealant, looks to solve a problem that really does not exist for most road bikes and even most gravel bikes, results in far more expensive tires and if you ever get a flat out on the road that the sealant can not seal (happens way more often than the tubeless hypesters want to admit), if you do not have a spare tube you are either walking back to your car/home or calling someone to pick you up. And even if you have a spare tube, it is a bloody mess to try to repair with sealant going everywhere. Thanks and no thanks.
