Product Overview
The TUBENOX Puncture Resistant TPU Inner Tube 700×18–28C was developed for riders who want something tougher than an ultralight race tube without carrying the extra weight of a traditional butyl spare. At only 25g, it stays incredibly compact while adding another layer of confidence for everyday road riding.
It fits 700C tires from 18mm to 28mm and works equally well as your primary tube or the spare that lives in your saddle bag until the day you need it.
What You'll Notice
Less Weight at the Wheel
Weight matters most when it's rotating.
Replacing a standard butyl tube with a 25g TPU tube removes unnecessary mass from the wheel, making the bike feel more responsive when accelerating, climbing, or changing pace.
Easier to Pack
Space disappears quickly once a multi-tool, CO₂ cartridge and tire levers go into a saddle bag.
This tube folds into a compact bundle, leaving room for the rest of your essentials.
Better Prepared for Everyday Roads
No tube can promise you'll never puncture.
What TPU can do is stand up better to everyday abrasion and small road hazards than conventional rubber tubes, making it a practical option for riders who spend plenty of time outdoors.
Where It Fits Best
This model was created with performance road bikes in mind, but it isn't limited to race day.
It's equally suitable for:
- Fast weekday training rides
- Weekend club rides
- Gran Fondos and endurance events
- Lightweight emergency spare kits
- OEM road bike builds
If your bike runs 700×18–28C tires, this tube is ready for the job.
A Smarter Upgrade Than You Might Expect
Cyclists often spend hundreds of dollars reducing weight through wheels, drivetrains, or carbon components.
Changing the inner tube is far simpler.
A lighter, more compact, and more puncture-resistant tube won't transform your bike overnight, but it's one of those upgrades you'll notice every time you accelerate, every time you pack your repair kit, and every time you finish a ride without stopping to fix a flat.
That's exactly why more riders-and more bicycle brands-are making the switch to TPU.

Questions We Often Hear
1. Can I replace a butyl tube with this one?
Yes. It fits the same tire sizes and installs in exactly the same way.
2. Is it only for racing?
Not at all. Many riders choose this model simply because it's easier to carry and takes up much less room than a standard spare.
3. Will it work with carbon wheels?
Yes. Choose the valve length that matches your rim depth.
4. Can TPU tubes be repaired?
Small punctures can usually be repaired using patches made specifically for TPU material.
