TPU inner tubes offer significant weight savings and compact storage compared to traditional butyl tubes, but durability concerns exist regarding slow leaks and material limitations.
Pros
- Significantly lighter (2-3 times lighter than butyl tubes)
- More compact and easier to store or carry
- Better puncture resistance than butyl tubes
- Superior air retention requiring less frequent pressure top-ups
Cons
- Can develop slow leaks after 200-300 km of use
- Plastic valve stems may develop leaks at bonded joints
- Does not fully recover original shape after inflation
- Difficult to reuse in smaller tires within manufacturer range
Key Facts
- Weighs 36g each (replaces 130g butyl tubes)
- Made of thermoplastic polyurethane (TPU) material
- Fits tire sizes 700C, 26", 27.5", and 29"
Reviews & Ratings
The reviewer tests RideNow TPU tubes to challenge GCN's claims about TPU tube characteristics. He finds that while TPU tubes are not completely inelastic, they do not fully recover their original shape after inflation, making reuse in smaller tires difficult. He recommends using fresh tubes for flats and patching them later with proper patch kits like Park GP-2.
AI Summary
Pros
- Metal valve stems available (unlike plastic ones that can leak)
- Can be patched successfully with proper patch kits like Park GP-2
- No issues with phantom punctures when using higher quality tubes
- Heavier weight TPU tubes (40-45g) can mitigate heat issues with rim brakes
Cons
- Plastic valve stems can develop leaks at the bonded joint over time
- TPU tubes do not fully recover their original shape after inflation
- Reusing TPU tubes in smaller tires (even within manufacturer range) is difficult
- Cheap TPU tubes may have more issues with phantom punctures
- Potential heat issues with rim brakes on carbon rims during prolonged descents
Key Points
- TPU is inelastic but not completely - tubes don't recover all deformation after inflation
- RideNow tubes tested were rated 18-32mm
- Tubes showed 20-40% diameter increase when overinflated beyond specifications
- Proper patching requires rubber cement and tube material patches, not stickers
- Metal valve stems are now available and can be screwed down to anchor to the rim
The reviewer mentions the RideNow TPU tubes as part of a tire and tube upgrade, stating they are significantly lighter than the original Specialized inner tubes and contribute to reduced rolling resistance.
AI Summary
Pros
- Saved 56g of weight per wheel compared to original tubes
- Reduced rolling resistance
Key Points
- Weighs 36g each
- Replaced 130g Specialized inner tubes
The reviewer discusses TPU tubes from AliExpress in general, not the specific RideNow TPU Bike Inner Tube model. They state that TPU tubes are the lightest, strongest, and most packable insurance policy for flats, even with tubeless setups. They found a deal for two tubes, tire levers, and a patch kit for $12, which is significantly cheaper than brand-name alternatives like Pirelli. The tubes are available in various sizes for road, gravel, and mountain biking and are small enough to be left in a repair kit indefinitely.
AI Summary
Pros
