A Duro Thornproof inner tube in 26" x 1.50/1.75 Thornproof: a thicker butyl wall built to resist the thorns, glass and wire that flatten a standard tube, for commuters, kids' bikes and anyone tired of roadside repairs.

Highlights

  • Size 26" x 1.50/1.75 Thornproof (40/47-559)
  • Extra-thick butyl wall — resists small punctures a standard tube won't
  • Choose your valve type and length
  • Heavier than a standard tube — trade a little weight for fewer flats

Fit and compatibility

Fits tyres in the 26" x 1.50/1.75 Thornproof range (ETRTO 40/47-559). Check the width printed on your tyre sidewall sits inside this range, and pick a valve length long enough to clear your rim depth.

Duro tubes are covered against defects in materials and workmanship. Punctures, pinch flats from incorrect fitting, over- or under-inflation and valve damage from a poorly fitted pump head aren't covered.

For warranty support, return the item to Tune Cycles with your proof of purchase and we'll manage the claim with the distributor for you. This cover is in addition to your rights under the Australian Consumer Law.
