The sealant for the tyre casing is the same "S" treatment as used on the TE and SC series tyres.
Latex Inner Tube - Used in Challenge tubular and tubeless tubular tyres. Available as accessory inner tubes for clincher tyres. Challenge's own latex formula delivers higher resistance to punctures due to elasticity. Unique seamless construction, no bumps for smooth ride. Lightweight, supple performance for less rolling resistance than rubber butyl tubes. Will require more regular inflation
