Slime Presta Valve Tube

This tube is designed for 700c tires with a width range between 28mm and 35mm. Please check the sidewall of your current tire to ensure it falls within this range before purchasing.

The tube comes pre-filled with Slime sealant, which coats the inside of the rubber. If you get a puncture up to 3mm (1/8 inch) in the tread area, the sealant is forced into the hole by air pressure to create a durable, flexible plug.

Yes. This tube features a removable valve core, which allows you to easily inject additional Slime sealant if you want to refresh the protection after the initial two-year lifespan.

This tube uses a Presta valve, which is standard on most road and performance hybrid bikes. Ensure your rim is drilled for a Presta valve (the thinner, threaded type) rather than a Schrader valve (the wider, car-style type) before installing.

While the pre-filled sealant does add some weight compared to a standard, empty tube, most commuters find the trade-off for flat-tire protection well worth the minor increase in mass.
