Product information

Description

AUTHOR AT‑MTB‑29" AV40 is a replacement inner tube designed for 29" mountain bike tyres with widths from 1.95 to 2.35 inches. The tube is made of durable black rubber and fitted with a 40 mm Schrader (AV) valve for compatibility with standard pumps and inflators. It provides airtight sealing and straightforward installation, suitable for routine repairs, roadside fixes and as a spare for off‑road rides.

Advantages

The inner tube features robust rubber construction that resists punctures and provides reliable air retention under varied riding conditions. The 40 mm Schrader valve ensures easy inflation with commonly available pumps and gas cartridges, while the 29" sizing and tyre width range make it compatible with most modern mountain bike setups. Lightweight and compact when folded, the tube is convenient to carry in a saddlebag or backpack.

Suitable for

Repairing punctures on 29" mountain bike tyres with width 1.95–2.35"
Keeping as a spare tube for trail rides and commuting
Quick roadside replacement during off‑road or cross‑country trips
Workshops and bike shops stocking common MTB spares

Key specifications

Tyre diameter compatibility: 29 inches
Tyre width compatibility: 1.95–2.35 inches
Valve type and length: Schrader (AV), 40 mm
Material: rubber (black)
Intended use: mountain bike (MTB) inner tube

How to use

Inspect the tyre and rim for embedded debris before installing the tube. Partially inflate the inner tube to give it shape, insert it into the tyre, align the valve with the rim hole and seat the tyre bead evenly around the rim. Inflate gradually to the tyre manufacturer’s recommended pressure while checking that the bead sits correctly and there are no pinches. After installation, recheck the tyre pressure and perform a short test ride to confirm airtightness.

Usage recommendations

Carry a spare tube of the same specification when riding off‑road. Use a pump or inflator compatible with Schrader valves and avoid overinflation beyond the tyre’s recommended pressure. Regularly inspect tyres and rim strips to reduce the risk of repeated punctures.
