Tube no. 21 from SCHWALBEIf you get a flat tire on the road, you won't get any further. That's why it's best to take a suitable Spare Tube with you on your bike tour. That way, you can continue riding soon and patch the defective tube during the break or later at home. The tube must fit! You can tell which size Tube is the right one by looking at the sidewall of most Tires. The first two digits of the ETRTO dimension indicate the tire width, while the following digits indicate the inner diameter of the tire in mm. The no. 21 covers numerous widths for 27.5" (650b) tires. For the valve and the correct length, it is best to use the old tube as a guide: the Schrader AV valve for the No. 21 is 40 mm.
