More Comfort and Protection with the Right Bicycle Tube for Your City Bike

Woman rides through Berlin on a City Bike

Most city and touring bike riders don't think about a bicycle tube — unless they get a flat. That's why many city cyclists still ride with the same black butyl inner tubes that have been used for over 130 years, even though they no longer reflect the latest technology. The right tube can make a big difference in both puncture protection and riding comfort. Here, we introduce you to AERON/TPU tubes, which — unlike classic black butyl tubes — are made from thermoplastic polyurethane, or TPU for short. 

Touring Tubes from AERON/TPU

City/Tour – UltraProtect

Outstanding puncture protection for touring and daily commuting. Low weight and reduced rolling resistance increase the fun factor on every ride.

What makes AERON TPU tubes so superior?

Our TPU tubes are ideal for city riding and traditional touring. They also provide many benefits over a comparable butyl tube:

  • They are up to 69% lighter. 
  • They exhibit lower rolling resistance. 
  • They are considerably more resistant to punctures and other flats. 
  • They are more sustainable because TPU is 100% recyclable. 
  • They fold into a much smaller size, occupying significantly less space. 
  • They can be ridden at lower pressure, which greatly improves riding comfort and grip. 
  • They are just as easy to swap out as butyl tubes (unlike, for example, tubeless systems . 

Additionally, TPU is less permeable than butyl, meaning the tube maintains the correct tire pressure  for much longer.

The perfect bicycle tube for your city bike

AERON/TPU tubes fit every bike type and riding style — whether you're just heading into town for errands, commuting to work, or going on a longer, more athletic ride — essentially like your old butyl tubes. There's a suitable tube for every tire size  and the matching valve for each rim hole. The three most common valve types are the Schrader valve (AV), the Presta valve (SV), and the traditional Dunlop valve (DV). Presta and Schrader valves are available from AERON/TPU for city and touring tubes.

If you're unsure which tube fits your wheel diameter or exactly what tire width you're using, you'll find all the specifications — in both inches and millimeters — printed on your bike tires, on the rim, and on the tube packaging. Just match them up, install the tube, and ride. For more helpful tips and advice on switching from butyl to AERON/TPU, check out our magazine
