30g Ultralight 700C Bike Inner Tube TPU Road Bicycle Tire 28'' Compatible with 700x18/23/25/28/30/32C Presta Valve 45/65/85mm(Include Bike Inner Tire Patch Repair Kit)

Surprised how these feel on road bike. Super light, roll great. They do need pumping up between rides but so far no punchers.I’ve given up on the faff of tubeless.

Don’t waste your money , puncture resistance is rubbish, front wheel has punctured 3 times in as many weeks . Same course as I did with continental butyl , no increase in speed , patches to repair don’t work , have reverted back to butyl , the above is a solution looking for a problem !

Great weight saving and reduced rolling resistance for these tubes. Easy to install.The ride seems quite harsh at 100psi and they are quite prone to pinch flats as the photo shows. Further testing needed from me. Bought 6 and have 4 left. Might stick with my schwalbe butyl tubes and keep these for on the road spares

really light. hardly know its in your jersey pocket. Not needed to use them yet, as i run tubeless and these are just for emergencies.

Only 1 star,+ super lightweight ,- very easily punctured, I fitted these with new armoured 32 mm tyres, rear developed a puncture.- not easy to patch, holes very difficult to see, but not feel.- Glue patches dont stick, very much a temp fix.- expensive, it would seem these are essentially single use based on my experience.I’d carry one as a spare, but wont be doing long rides on these as they are not reliable.

Value for moneyThe whole content of package just makes senseYou guys must be discerning cyclists everyone is talking about

The media could not be loaded. Only just got round to using these. Both tubes have some kind of fault which seems to be where the metal section of the valve meets the plastic section (as can be seen in the video) therefore will not stay inflated.

They punctured after one ride. The manufacturer has been in contact and offered a full refund. I am 85 kg, so Ultralight was probably the wrong choice for me, I will try their CYCLAMI 38g tpu. I am impressed with the manufacturer (and have other products of theirs - including electric pump)
