Although Challenge Handmade Tubular Tyres are made with the highest quality materials and processes, like a fine wine, they must be stored and treated with care to have a long life and provide the highest level of performance, comfort and control.

After being ridden in mud they should be washed with a light detergent with a very soft brush and fully dried prior to being stored in cool, dark, dry room (yes, like a wine cellar).

Handmade tubular tyres should never be stored wet or for long hours in direct sunlight or high heat (on a terrace, in or on a car or in a sunny shop window)
