Cotton is naturally soft and supple material compared to Nylon. Challenge's Corespun Cotton thread delivers the ideal balance of high performance and price.TE and SC series tyres have a high 320tpi thread count. TE (Team Edition - cyclocross) and SC (Service Course - road, tri, time trial and track)



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.



PPS Ganzo - A higher level of puncture protection utilising a multi-component fabric strip with a tighter weave that still remains flexible.
