A road.cc review found that Nutrak’s Presta-valve TPU tube combines a thicker construction with a metal valve, weighing 56.8g. It had no punctures during the test, but is heavier and bulkier than other TPU tubes tested, and the reviewer questioned whether its potential durability benefit justifies the trade-off.
A road.cc review of Nutrak’s Presta-valve TPU inner tube found it weighed 56.8g and had no punctures or problems during the reviewer’s testing, while offering a thicker construction and metal valve than many lightweight TPU alternatives. The test also found it was heavier and larger to pack than other TPU tubes, leaving its potential durability advantage unproven over the longer term.
The reviewer described the tube as a middle ground between traditional butyl and very light TPU models. At 56.8g, it weighed substantially less than the reviewer’s standard butyl tube, which weighed 138.4g. But the tested standard-size TPU alternative weighed 27.8g, and a gravel TPU tube designed for 40–50mm tyres weighed 48.9g. The comparisons come from the reviewer’s own tests, not a controlled assessment of all tubes on the market.
The tube’s metal valve was another point in its favor. The reviewer said it felt more robust than the plastic valve stems found on many lightweight TPU tubes, a potential benefit for riders using electric pumps. Nutrak’s product description also claims the copper valve improves strength and corrosion resistance, and says the tube offers high air retention and compatibility with most Presta-valve pumps. Those are manufacturer claims; the review did not report independent measurements of corrosion resistance or air retention.
The reviewer reported no punctures or other problems during the test, but cautioned that this was not enough to establish long-term durability. The tube received an overall rating of 5/10 in the review, with quality and performance each rated 8/10 and value rated 5/10. The reviewer said they would not buy it and would probably not recommend it, citing the weight and size penalties against other TPU options.
The Durability Trade-Off
For riders choosing a spare inner tube, the review highlights a practical compromise: Nutrak retains a substantial weight saving over the tested butyl tube, but gives up some of TPU’s usual advantages in low weight and compact storage. According to the reviewer, two standard TPU tubes could fit in roughly the space occupied by one Nutrak tube. That could matter to riders carrying multiple spares on long rides or trying to limit luggage on a bikepacking trip.
The metal valve may appeal to cyclists concerned about using electric pumps with plastic valve stems. But the review’s testing did not establish that the thicker tube lasts longer or resists punctures better. Buyers are weighing a potential durability benefit against a measurable weight and packing-size penalty, with the durability case still uncertain. The review also questioned the value proposition, noting that some retailers offered two standard TPU tubes for around £11; prices and availability can vary.

How It Compares With Tested Tubes
TPU, or thermoplastic polyurethane, is used in inner tubes that can be lighter and pack smaller than conventional butyl tubes. That makes it attractive as a spare for cyclists who want to reduce carried weight and storage space. Nutrak’s model takes a less weight-focused approach, using what the report describes as slightly thicker TPU and a copper-colored metal Presta valve.
The road.cc reviewer compared the tube with a standard butyl tube and two TPU alternatives, including a gravel tube intended for wider tyres. The Nutrak weighed more than both TPU examples, though it remained much lighter than the tested butyl tube. The report also noted that lightweight TPU tubes can be inexpensive: it cited two standard tubes available from some retailers for about £11, and a previously tested PSIKIC tube priced at £15.99. These are examples in the review, not a complete or current market price survey.
“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.”

Long-Term Puncture Resistance
The report does not specify the length or conditions of the test, the number of tubes tested, or the mileage each covered. It therefore cannot show whether the thicker construction meaningfully improves puncture resistance or service life compared with thinner TPU models. The reviewer directly cautioned that having no punctures during testing was not enough to make a definitive claim about long-term durability.
It is also unclear how the tube performs across different tyre widths, pressures, temperatures or pump types. The review does not provide independent test results for the manufacturer’s claims about air retention, valve corrosion resistance or compatibility with most Presta pumps. The price comparisons reflect the examples and retailer offers cited in the review; current prices may differ.

Check Fit and Current Pricing
The review does not announce a product change, recall or follow-up test. Riders considering the tube can compare its valve type and compatibility with their wheel and pump, then check current retailer prices and the dimensions of the packed tube against the alternatives they carry. The key unanswered point is whether longer-term testing would confirm a durability advantage large enough to offset its extra weight and bulk.

Key Questions
How much does the Nutrak TPU tube weigh?
The road.cc review measured it at 56.8g. The product information quoted in the report lists its weight as 56g.
How did it compare with the tested TPU alternatives?
The reviewer’s standard-size TPU tube weighed 27.8g, while a gravel TPU tube for 40–50mm tyres weighed 48.9g. Both were lighter than the Nutrak, though results apply to the specific tubes tested.
Did the review prove that the thicker tube is more durable?
No. The reviewer reported no punctures or problems during testing but said that was not enough to make a definitive claim about long-term durability. Test length and mileage were not stated.
What is the reported advantage of its metal valve?
The reviewer said the metal valve felt more robust than plastic valve stems used on many lightweight TPU tubes, which may matter to riders using electric pumps. The review did not report a comparative valve-strength test.
What overall rating did the tube receive?
The road.cc review gave the Nutrak tube an overall rating of 5/10, with 8/10 for quality, 8/10 for performance and 5/10 for value.
