Clinchers do have their advantages. Changing tires is much quicker since it does not involve a lengthy glueing and curing process so a rider can have a large selection of tires at their disposal. Until recently, clinchers also generally had more cutting edge tread patterns than the more traditional tubulars. Some enthusiasts even went as far as to send Michelin Mud tires (a popular clincher tire) to Dugast (a manufacturer of high end tubular tires) to have a modern tread pattern incorporated into a traditional tubular. However, since 2005 several tubular manufacturers have designed more modern style tread patterns, namely Dugast with its Rhino, Tufo with its Flexus and Challenge with its Grifo and Fango. Lastly, clincher tires generally cost less than tubulars.
