At Simply Bearings we stock a comprehensive range of Dr Sludge self-sealing inner tubes with either presta or Schrader valves. If you're a keen cyclist or bike commuter, then you'll appreciate how invaluable these self-sealing bike inner tubes are when a flat tyre can ruin your day. Dr Sludge self-sealing tubes are pre-filled with a liquid rubber solution to the precise dosage, meaning you need never suffer with a flat tyre again.
How does it work? If you have a puncture, the rubber solution in the tube is pushed into the hole and seals immediately when it comes into contact with the air. Punctures are instantly sealed with no loss of tyre pressure and will work time after time, keeping you on the road for longer.
Every Dr Sludge inner tube undergoes individual quality testing before it leaves the factory. Easy to fit, they'll give you extra protection on wet winter roads and are ideal for riding in rainy conditions. And because these bike inner tubes work time after time, you'll stay safe whenever you're riding.
The water-based solution is anti-corrosive so it won't damage your wheel rims, and the inner tube and tyre won't stick together, making them easy to replace. Even better, the liquid rubber will never dry out whatever the temperature, so you can always rely on a Dr Sludge self-sealing inner tube to get you home safely even if you have a puncture.
Available in all standard sizes to fit any tyre rim, a Dr Sludge inner tube with puncture protection from Weldtite is the smart option when you want to keep cycling for longer. Available with free UK delivery, these products can also be dispatched on the next day or same day if you need them in a hurry. If you need bike inner tubes shipped internationally, just add them to the smart cart and it'll calculate our low international delivery costs.
