Slime Smart Tube Bicycle Inner Tube

This tube is designed specifically for 700c tires with a width between 19mm and 25mm. Please check the sidewall of your current tire to ensure it falls within this range before purchasing.

Yes, because the tube comes pre-filled with sealant, it will be slightly heavier than a standard, empty inner tube. However, the trade-off is the added reliability and puncture protection, which most riders find worth the negligible weight increase.

No, this specific model is equipped with a 48mm Presta valve. You should only purchase this if your wheel rims are drilled for Presta valves.

The sealant is engineered to automatically seal tread area punctures up to 3mm in diameter. It is highly effective for thorns, glass shards, and small wire debris commonly found on roads.

Not at all. You install this tube exactly the same way you would a standard rubber inner tube. Just be careful when inserting it into the tire to avoid pinching the rubber.

The sealant is designed to remain effective for the lifespan of the tube. While you may need to top off your air pressure periodically as you would with any tube, the puncture-sealing properties remain active throughout the tube's useful life.
