Specialized Standard Presta Tube - Mountain Bike size 29" x 1.75-2.4". This lightweight but strong butyl rubber tube has the unique benefit of factory applied talcum powder INSIDE the tube. Specialized claims this inside talc is all that is required for a long life, reliable tube that is more resistant to pinch flats due to the talc 'lubricant'. Note: these lightweight tubes are not thorn resistant. They make other Heavy Duty tubes for that. This standard tube is competitively priced. However, if you are running very low tire pressures (under 15 psi), you should consider a more expensive and time-consuming tubeless setup. But these standard tubes are fine for everyone else. Specialized also makes a similar "Standard Presta" light weight, long lasting, pinch resistant tube with internal talc for 700 size road bike tires.
