## Summary description

WELDTITE DR SLUDGE is a bicycle inner tube 29" x 2.10–2.35 with integrated puncture protection fluid and a Schrader valve. Designed to reduce the risk of flats by sealing small punctures, it suits MTB and trail tyres within the stated size range. Practical for commuting, off-road riding and recreational cycling where added puncture resistance is required.

## Long description

WELDTITE DR SLUDGE is a bicycle inner tube sized 29" x 2.10–2.35 with a Schrader valve and integrated puncture protection fluid. The tube is constructed for use with mountain bike and trail tyres within the stated diameter and width range. The incorporated sealant fluid helps close small punctures and slow air loss, offering additional protection compared with standard butyl inner tubes while remaining compatible with typical tubed wheel setups.
Advantages
The integrated puncture protection fluid provides automatic sealing of small punctures without adding external accessories. The Schrader valve offers robust compatibility with common pumps and easy inflation at service stations. The tube’s size range covers a wide selection of 29" MTB and trail tyres, making it suitable for riders who want straightforward installation and improved flat prevention. The design preserves normal tyre handling and ride characteristics while reducing the frequency of roadside repairs.
Suitable for
29" mountain bikes and trail bikes with tyres 2.10–2.35" wide
Commuting on mixed urban and unpaved surfaces where puncture resistance is beneficial
Recreational off-road riding and light trail use
Key specifications
Tube diameter: 29 inches
Recommended tyre width: 2.10–2.35 inches
Valve type: Schrader (standard automotive-style valve)
Material: butyl rubber inner tube with integrated liquid sealant
Purpose: puncture-reducing inner tube for tubed tyre systems
How to use
Install the inner tube in the tyre and rim following standard tube-fitting procedures: partially inflate the tube to give it shape, place it inside the tyre, mount the tyre bead onto the rim ensuring the tube is not pinched, then fully inflate to the tyre manufacturer’s recommended pressure. The sealant is already inside the tube; it remains liquid until a puncture occurs, at which point it moves to and seals small holes. Periodically check pressure and inspect the tube after significant impacts or punctures to confirm the sealant has performed as expected.
Usage recommendations
Use with compatible tubed 29" tyres within the 2.10–2.35" width range and rims designed for Schrader valves. Store the product at moderate temperatures and avoid long-term exposure to direct sunlight to preserve the sealant’s performance. If a large or multiple punctures occur, perform a conventional repair or replace the tube. Regularly check tyre pressure before rides and re-inflate to the recommended level for load and terrain.
