I’ve got 32mm wide tires on my road/gravel bike. Currently looking at TPU tubes and I’ve got two options:

  • 32-47mm
  • 18-32mm

So, is it better to get one over the other, or will they both work equally well? Never used TPU tubes before, so I wouldn’t even have a reference to compare these.

    However, why are you getting into TPU? If it’s for weight or rolling resistance, then definitely run the smaller tube.

    Apparently, they offer much lower rolling resistance, much lower weight, are way more compact (on bike repair kit), and should be more durable, too.

    Surely there’s another brand of tubes with a better size range? That’s my best answer tbh.

    I’ll keep looking, but apparently this particular brand of (rather inexpensive) tubes are extremely popular and came recommended by someone in a riding group I was in.

      Based off all that, I’d run the 18-32. Besides, assuming you’re not buying in bulk, and you’re not doing rural bike-packing, then getting a flat or other mechanical won’t be too catastrophic or costly. Try em out a lil, and report back on how you like them :)
