Why "Challenge" tires?
The only point of contact that a bicycle has with the road is with its tires.
So why compromise the feeling of your beautifully assembled expensive bike
by using cheap, non-performing tires?!?

"Challenge" tires can help reduce shock and reduce rolling resistance,
which leads to generally more comfortable, faster and longer journeys.

Part of this is achieved by using a certain type of rubber or rubber mixture.
Fortunately, the challenge is to produce where the natural rubber drips from the trees
instead of using artificially produced petroleum-based rubber,
which clearly does not have the same properties as natural rubber.
