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!
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
.
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.
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.
