Fine, but I'd struggle to recommend - differences aside from price are marginal!
With summer finally arriving I got round to fitting one of these tubes on my new 60mm deep section rear wheel for a test run.
The fitting process is a bit more fiddly than conventional butyl tubes – butyl tubes tend to stay where you put them and out of the way while fitting a tyre, whereas these tend to flop around more, so you find yourself poking them back into the tyre casing a bit more.
With that said, I didn’t have any trouble, and they went on easily enough.
Rolling resistance differences from tests seem pretty marginal, and unfortunately I’ve heavy enough that the weight savings are only a miniscule amount of system weight, so the benefit for me is mainly that they are a bit lighter and more compact to carry as spares, and on that front they are a somewhat noticeable improvement.
You are paying an awful lot more for that improvement though – I think my policy will probably be to carry these as spares but stick to butyl the rest of the time!
CYCLAMI TPU Inner Tubes
Two of these innertubes saved me 207g off my butyl innertubes, rolling resistance is good, on rough roads they do feel a bit better than butyl tubes, i’m using 30mm tyres at 70psi, i.ve done several rides without any problems, they do lose a bit of preasure after about 4 to 5 days, i don’t know how good they to patch and i would buy more if i need them.
Funtional but Unusual Appearance
Looks very unusual like super strong green rubble bags! But so far really holds. I am carrying a rubber replacement for now but if this holds over next 5 -10 rides i will buy more for my spare carry as it is so lightweight comparitively it is a no brainer. Only challenge is fitting it is a little more fiddly due to it being more lightweight/flappy.
Love they come with green caps and standard fasteners.
*Addendum 25/5/24 – these were on the bike 2 weeks sat in the house and went completely flat. Stick to rubber. Good emergency get you home kit but not a long term swap ou
Tpu Tubes
As someone that’s only ever used rubber tubes and latex I took a chance on tpu tubes I was so suprised on how easy they installed on to tight tyres compared to rubber or latex were used to get a pitch flat every now and again the tpu slightly inflated as would any other tube used a tyre glider to get tyre on checked to make sure tube wasn’t pinched inflated tube to 40psi rechecked then inflated to 116psi test rode found the tpu was faster and smoother would recomend I’ve been converted give them ago
.
Super light, and full length valve.
Nice tube. Needed a full length valve / tube that could be capped to stop the valve rattling in the wheel – this did the job perfectly and is super light. Bit expensive but did the job and is slightly better than the equivalent butyl tube with extenders.
Lightweight tubes - updated
My first time with TPU tubes. Was unsure having read reviews but had no issues. Much easier to fit tyres to than butyl, huge weight saving and they seem very durable. More than happy, so ordered some more
Update – had a puncture then tried to use the repair patches which are hopeless and allow air to pass, so now carry a spare tube
Very lightweight, and seem to be holding up well
I replaced my tyres and inner tubes at the start of the year thinking I would be able to give them a good try out, but unfortunately the weather has been pretty miserable this winter so I have only been out a few times.
Saying that, these have held up to the couple hundred miles I have done without any issue. I’m not sure if i can tell any difference between these and the latex ones that I was using, but I suppose that is what you are looking for. It’s amazing how thin and light they are when they are out of the tyres, so they are probably perfect for carrying a spare.
Great quality and benefits
These CYCLAMI brand tubes are amongst several TPU I’ve tried after Lockdown. I’m a keen cyclist and a gadget freak, and first got into TPU when the price became “affordable” in around 2022.
I have my own reasons therefore for choosing TPU: I’m not a pro cyclist, but the ease of carrying, the ‘robustness’, and the (for me) noticeably different ride over butyl tubes means they are something I like.
These CYCLAMI tubes are great, and given that autumn > winter is my ‘prime puncture zone’ I’ve already needed to use one of these.
Fitting, in my opinion, is easier than butyl tubes. These tubes are a single mould, with the only seam being around the valve. In my two bikes (with different rim depths) I’ve struggled with valve clearance, but these are very generous.
The price is obviously a lot higher than decent butyl (or even latex) tubes, but I guess I’m now a TPU fan… and as I’m not a pro-level cyclist, I don’t need to replace them that often.
Also, the inclusion of a specific patch kit is welcome – as I’ve tried aftermarket TPU patches before with little success – so that’s a nice touch.
Very happy so far, will update the review if anything changes!
Pretty light and pretty pricy.
I run tubeless in all my bikes, so tubes are only for carrying round in the hope that you never need them. With that in mind they fit the bill, being light and compact so they’re easier to carry round than a normal tube.
My concerns will be durability and roadside repairs. I have no idea how they will hold up to thorn season, and the fact that they have a specific type of patch makes me worry about sorting them out in the cold and rain.
My other concern about these is the price. I could get 6 or 7 tubes for the prices of two of these, so if they fail in relation to any of my concerns above I don’t know that I will replace them like for like.
What’s not to like?
Having used the orange brand in my summer bike, thought I’d give these a spin. Can’t tell the difference from the orange ones TBH.
Same supple feeling, light weight, if there as durable as the orange ones time will tell. Absolute bargain (I know butyl ones are pence) if you consider orange ones are around 25 plus patches at 5 plus delivery your looking at 30 there abouts double that because you need 2. 25 pounds for 2 and patches included, no more faffing with sealant. For on the road you can’t go wrong. If you still need convincing look up OZ cycles on YT.
I can’t believe how light these are
These are fluorescent lime green, feel like plastic/polyethelene (rather than rubber) and are very light weight.
I have not put them on the bike yet, but I have put one of them in my saddle bag to use if I have a flat (I have left a continental one in there too, as a backup fir now).
I can see some big advantages with these, as being a plastic/polyethelene material, they should not lose air between rides like my rubber ones do, and being so light they should help with weight saving too.
They are expensive, but if they live up to their promises of being more puncture resistant, then they will be worth it. I normally get two punctures a year, so once Spring comes around and I can get out on the road again, I should be able to see how good they are quite quickly.
The valve is also a good length, and will fit through my deep carbon Mavic wheels.
Better than I thought they would be.
Interesting to use. Holds air so fa
So I used one of these already inside a road bike wheel. The other I am carrying as a spare for flats while commuting on my hybrid bike (also 700c but ~2″ wide).
Putting it into the road bike wheel was not as easy as a normal butyl rubber tube. It’s very thin this PU one, and is formed flat. This meant it was very easy for it to fold over itself while inserting, and until I added a bit of air to help, it was quite impossible to get it inside the tyre without it folding, falling out, etc. The instructions to say to add 5psi for fitting.
The thinness made me worry about the tyre beads scraping across it while fitting. It is in and holds air, but I strongly worry that I will end up damaging it while fitting a proportion of the time.
