## Summary description

Inner tube by WELDTITE, model DR SLUDGE with built-in puncture protection fluid for 29" wheels and tyre widths 2.10–2.35. Equipped with a Presta valve, this bicycle tube is intended to reduce pinch flats and small punctures by coating the inner surface. Suitable for mountain and trail bikes using 29" x 2.10–2.35 tyres, offering straightforward installation and maintenance.

## Long description

The WELDTITE DR SLUDGE inner tube with integrated puncture protection fluid is designed for 29" wheels with tyre widths from 2.10 to 2.35. Fitted with a Presta valve, this tube combines standard butyl construction with a factory-applied sealing liquid that helps reduce small punctures and slow leaks by coating the inner surface. The tube is intended for mountain and trail bike applications where wider tyres are used and installation follows the same steps as for any regular Presta-valve inner tube.
Advantages
The built-in sealant reduces the need for immediate roadside repairs from minor punctures and slow leaks and can extend the time between servicing. A Presta valve makes the tube compatible with most mountain bike rims used for 29" tyres, while the butyl material provides reliable air retention and flexibility for wide tyres. Factory application of the puncture protection fluid ensures an even coating without separate sealant handling.
Suitable for
29" mountain and trail bicycles with tyre widths 2.10–2.35
Riders seeking reduced incidence of small punctures and slow leaks
Routine maintenance or replacement of worn or damaged inner tubes
Key specifications
Wheel size compatibility: 29 inches
Tyre width range: 2.10–2.35 inches
Valve type: Presta (French) valve
Construction material: butyl rubber with integrated sealing fluid
Intended use: mountain and trail riding
How to use
Inspect the tyre and rim for sharp objects or damage before installation. Partially inflate the WELDTITE DR SLUDGE tube to give it shape, insert it into the tyre, seat the tyre bead on the rim, then fully inflate to the tyre manufacturer's recommended pressure. If a puncture occurs, rotate the wheel so the sealed area passes the puncture point; the integrated fluid will coat and seal small holes. Follow standard safety checks after inflation to ensure proper seating and secure valve operation.
Usage recommendations
Store the inner tube in a cool, dry place away from direct sunlight and chemicals. For larger cuts or persistent leaks, replace the tube rather than relying solely on the integrated sealant. When inflating, use a compatible pump for Presta valves and adhere to the tyre pressure range printed on the tyre sidewall.
