A road.cc review found the Nutrak TPU inner tube worked without punctures during testing and has a sturdier metal valve than plastic-valve alternatives. At 56.8 grams, it was far lighter than the reviewer’s 138.4-gram butyl tube, but heavier and bulkier than other TPU tubes tested; long-term durability remains unproven.
Nutrak’s TPU bicycle inner tube with a copper Presta valve offers a more substantial build than many lightweight TPU alternatives, but a road.cc review found that choice comes with a weight and packed-size penalty. The reviewer recorded a weight of 56.8 grams and reported no punctures or problems during testing, while cautioning that this short-term experience does not establish long-term durability.
The tube is positioned between traditional butyl inner tubes and very light TPU models: it retains a substantial weight saving over butyl while using thicker TPU, according to the review. The reviewer’s standard butyl tube weighed 138.4 grams, compared with 56.8 grams for the Nutrak. Those figures are specific to the tubes tested and do not establish how the Nutrak compares with every model on the market.
Against other TPU examples in the same review, the Nutrak was heavier. A standard-size TPU tube weighed 27.8 grams, and a gravel tube intended for 40–50mm tyres weighed 48.9 grams. The reviewer also found the Nutrak took up more space when packed, estimating that two standard TPU tubes would fit in roughly the space occupied by one Nutrak.
The reviewer highlighted the metal valve as a practical difference, particularly for riders using electric pumps. The review says the valve felt more robust than plastic valve stems found on many lightweight TPU tubes. The reviewer gave the product an overall 5 out of 10, describing it as functional but difficult to justify against lighter, smaller alternatives. The manufacturer’s product description claims the tube offers high air retention and a copper valve intended to improve strength and corrosion resistance; those claims are not independently established by the test results provided.
The Trade-Off for Spare Tubes
For riders choosing an inner tube to carry as a spare, weight and packed volume can affect what fits in a jersey pocket, saddle bag or bikepacking kit. The review’s measurements suggest Nutrak’s model still saves considerable weight over the tested butyl tube, but gives up some of the compactness and low weight associated with TPU.
The metal valve may appeal to riders who want a sturdier connection for a pump, including an electric pump. But the reviewer’s experience only speaks to how the valve felt in use; it does not establish that plastic-valve tubes will fail or that the copper valve produces better overall reliability. Buyers are weighing a potential construction benefit against measurable differences in weight and size, with no long-term durability result in the review.
Price is another part of that decision. Road.cc said some retailers offered two standard TPU tubes for around £11, and cited a PSIKIC tube previously tested at £15.99. The report did not provide the Nutrak tube’s exact price, so those examples cannot establish a direct price comparison. The reviewer nevertheless questioned whether any possible durability advantage would make the trade-off worthwhile if multiple lighter tubes cost about the same as one Nutrak.

How Nutrak Fits the TPU Market
TPU tubes are commonly chosen as a lighter, more compact alternative to conventional rubber butyl tubes. Nutrak’s product takes a less minimal approach: the review describes thicker TPU construction and a copper-colored metal Presta valve, rather than the plastic valve stems found on many lightweight models.
The source report includes the manufacturer’s claims that the tube is compatible with most Presta pumps, is compact to carry, and has high air retention compared with standard rubber tubes. It also lists a product weight of 56 grams; the reviewer’s measured figure was 56.8 grams. The review rates quality and performance at 8 out of 10, but value at 5 out of 10, reflecting the reviewer’s distinction between a product that worked during testing and one they would choose to buy.
Road.cc disclosed that its review contains retailer links that may earn the publication a commission on purchases, and stated that its reviews are independent. The supplied report does not describe the length of testing or a controlled comparison of puncture resistance, air retention or valve lifespan.
“I had no punctures or problems with the Nutrak tubes during testing, although that’s obviously not enough to make any definitive claims about long-term durability.”
— Road.cc reviewer
Durability Evidence Remains Limited
The report does not specify the duration or conditions of testing, and a lack of punctures during one test cannot establish how the tube will perform over extended use. There is no supplied long-term comparison measuring punctures, air loss, valve damage or service life against thinner TPU tubes or butyl models.
The manufacturer’s statements about air retention, strength and corrosion resistance are product claims, not outcomes demonstrated by the review’s reported test. The source also gives no exact Nutrak price, making a precise value comparison with the cited alternatives unavailable. It is not clear whether the reviewer’s measured results would apply across different tyre sizes or riding conditions.
Check Fit, Price and Test Data
The review does not announce a follow-up test or a forthcoming product change. Riders considering the tube can compare its valve type, weight and packed dimensions with alternatives available for their wheel and tyre setup, and check current retailer prices before buying. The review’s figures are a point of comparison, not a guarantee that every tube will weigh or perform identically.
Further evidence on long-term puncture resistance and air retention would be needed to establish whether the thicker construction delivers a durability benefit large enough to offset the extra weight and bulk. Until that is available, the review supports a limited conclusion: Nutrak’s tube worked during the reported test, while its claimed durability advantage remains unverified.
Key Questions
How much does the Nutrak TPU tube weigh?
Road.cc measured it at 56.8 grams. The manufacturer’s listed figure in the supplied report is 56 grams.
Did the reviewer experience any punctures?
The reviewer reported no punctures or problems during testing, but said the test was not enough to make a definitive claim about long-term durability.
How does it compare with other TPU tubes?
In the review’s examples, a standard TPU tube weighed 27.8 grams and a gravel TPU tube weighed 48.9 grams. The reviewer also found the Nutrak bulkier when packed.
What is the advantage of the copper valve?
The review says the metal valve felt more robust than plastic stems on many lightweight TPU tubes, which may matter to riders using electric pumps. The test does not establish a longer valve lifespan.
Did road.cc recommend buying it?
The reviewer rated it 5 out of 10 overall and said they would not consider buying it, mainly because lighter, smaller TPU alternatives seemed to offer a better trade-off. That is the reviewer’s assessment, not a universal verdict.
