## Summary description

WELDTITE DR SLUDGE is a bicycle inner tube 26" x 1.50–2.10 with integrated puncture protection fluid and a Presta valve. Designed to reduce flats by sealing small punctures, it fits mountain and hybrid tyres in the specified size range. Practical for commuting, trail riding and touring where extra puncture resistance and quick on-road repair are needed.

## Long description

The WELDTITE DR SLUDGE 26" x 1.50–2.10 Presta inner tube is designed for mountain and hybrid bicycles that use 26-inch wheels and tyre widths from 1.50 to 2.10 inches. This tube includes an integrated puncture protection fluid that helps seal small holes and slows air loss from typical road and trail punctures. Fitted with a Presta valve, the tube provides a standard, high-pressure-compatible connection for pumps and floor inflators. The DR SLUDGE model aims to reduce the frequency of roadside tube changes by offering immediate sealing action against thorns, small glass fragments and similar sharp objects.
Advantages
The integrated sealant fluid provides continuous protection while the tube is inflated, automatically sealing many small punctures without user intervention. The Presta valve ensures compatibility with common bicycle pumps and allows precise inflation to the recommended tyre pressure. The tube’s size range fits a wide variety of 26" mountain and hybrid tyres, making it a versatile spare for commuting, trail riding and touring. Constructed to standard inner tube dimensions, it remains easy to install and replace when necessary.
Suitable for
26" mountain bikes with tyre widths 1.50–2.10
Hybrid and commuter bikes using 26" tyres in the specified range
Trail and light off-road riding where puncture risk is moderate
Touring and bikepacking where on-the-road reliability is desirable
Riders who prefer fewer roadside tube changes and quicker recovery from small punctures
Key specifications
Wheel diameter: 26 inches
Tyre width compatibility: 1.50–2.10 inches
Valve type: Presta (French valve)
Integrated puncture protection fluid for self-sealing small holes
Intended use: mountain, hybrid and commuter tyres
How to use
Install the tube following standard tyre removal and fitting procedures: partially deflate and remove the tyre from the rim, take out the damaged tube (if present), insert the WELDTITE DR SLUDGE tube ensuring the Presta valve is correctly seated in the valve hole, and tuck the tube into the tyre bead. Partially inflate to settle the tube, then fully inflate to the tyre manufacturer’s recommended pressure. After inflation, rotate the wheel for a short time to allow the integrated sealant to distribute evenly across the inner surface of the tyre. In case of larger cuts or tears that cannot be sealed, remove and replace the tube as normal.
Usage recommendations
Use the tube within the specified tyre width and follow standard safety checks: ensure the tyre and rim tape are free of debris, check recommended inflation pressure, and carry a suitable pump and repair kit for larger damage. For long-term storage or prolonged high-speed use, periodically inspect for sealant effectiveness and consider replacing the tube if the fluid is depleted or if repeated punctures occur.
