Continental Cross King Shieldwall MTB Tyre Fast, grippy and versatile, Continental’s Cross King Shieldwall MTB Tyre is available in a huge range of sizes so that there is an option to suit every bike and rider. Shieldwall provides the puncture protection, with the layer of finely woven cross fabric preventing any penetration without adding too much weight or detracting from the supple ride provided by the 3/180 tpi construction. Traction is good across a variety of surfaces and conditions, making this an excellent all-round option, and durability from the PureGrip Compound is also impressive. The tyre is tubeless-ready but can also be used with an inner tube if preferred and it has been rated as compatible with electric bikes.
