27.5" Innertubes

27.5 / 650B tube fit guide

Match 27.5 inch inner tubes by 584 mm ETRTO, width and valve

Most 27.5 inch and 650B bicycle tyres use a 584 mm rim diameter, but the width range still decides which tube fits. Check the printed ETRTO on the tyre, then choose a tube that covers that width and the right Presta or Schrader valve for your rim.

650x52B / 52-584 guideUse this when an old sidewall says 650x52B, 27.5x2.10, 50-584, 52-584 or a nearby 584 mm size.27.5 inch tyresCompare matching 584 mm tyres before choosing a tube if the current tyre is worn or the width is unclear.650 tube routeCheck older 650 labels carefully: 650B / 584 is different from many 650A or 650C road-size markings.Protection and repairAdd rim tape, repair products or puncture protection when repeated flats come from the tyre or rim bed.

Confirm the 584 mm diameter

A 27.5 inch tube is for the 584 mm rim family. Do not use it for 26 inch / 559, 29 inch / 622 or old 650A / 590 wheels even when the inch or French-size wording looks close.

Match the width range

A tube marked around 37-54 mm can suit many 27.5 / 650B tyres, while wider MTB tyres may need a larger range. Compare the old tyre width before ordering.

Choose the valve before checkout

Presta and Schrader valves are not interchangeable on every rim. Match the existing valve hole and valve length, especially on deeper rims or e-bike utility wheels.
