Inner Tube WELDTITE DR SLUDGE Puncture Protection 29" x 2.10–2.35 Presta

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.
