  • Quality control for safer cycling: Each tube is checked twice at the factory to ensure safer cycling. Having the correct pressure means fewer punctures and reduced rolling resistance
  • 27.5 x 1.50 - 2.40"
Stephen Good quality inner tubes
Rayland These are difficult to get hold of for Schrader valves. Merlin is my go to shop for stuff like this
Mr Ilyasa another one to keep as spare/when riding
Mr Fraser Its an inner tube - it does what it should without surprises.
Mr Dantay Great product! Recommended.
Jonathan Reliable Schwalbe tube, good quality.
Thomas Always bought and used Schwalbe inner tubes as they seem to just keep going! Great quality at a great price from Merlin Cycles and good customer service.
Mr Ashdown Perfect spare tubes for an ebike with 650B tyres.
Spike Top quality tube. Ready as a spare, packs nice and small.
Mr Bowen Hard to find this size of tube with right valve locally. Merlin had it and at half the price of bike shop.
Andrew Not a lot to say really decent quality innertube, does what its supposed to.
Mr Morris Very good quality inner tubes. come with better dust caps than other brands I have bought. Paired with the Schwalbe marathon plus MTB tyres on my E bike hope to reduce the risk of punctures. Like the fact these are designed to be less porous and so retain air for longer.
LAVAU80 Great quality as always from Schwalbe.
