A Continental MTB tube with a Presta 42mm valve is a specific type of inner tube designed for mountain bikes, featuring a Presta valve with a length of 42mm. These tubes are made by Continental, a well-known manufacturer of bicycle tires and tubes5.
Here’s a breakdown of what this entails:
- Continental: This refers to the brand, Continental, known for producing bicycle tires and tubes5.
- MTB Tube: This indicates that the tube is specifically designed for mountain bikes. These tubes are typically more robust than road bike tubes to withstand the rigors of off-road riding5.
- Presta Valve: This is a type of valve commonly found on higher-end bicycles. Presta valves are narrower and often longer than Schrader valves (the type typically found on car tires). They require a pump with a Presta-compatible head or an adapter1.
- 42mm Valve: This refers to the length of the Presta valve. A 42mm valve is a versatile size that can fit a range of rim depths. Continental’s newest ultra light mountain bike tube featuring the 42 mm valve, replaces both the 36 mm and 48 mm sizes2.
Continental MTB tubes with a 42mm Presta valve are available for various wheel sizes, including 26″, 27.5″, and 29″ wheels. The appropriate tube size depends on your bike’s wheel size and tire width
