Where speed and trail tough cut-resistance intersect you'll find our Fast Trak CONTROL 2Bliss Ready tire. It takes the legendary tread design of the Fast Trak a step further by manipulating each knob with Finite Element Analysis'creating more consistent shoulder blocks for better cornering traction while also optimizing block spacing for better self-cleaning. The tread of this 2Bliss Ready version is also slightly wider compared to the S-Works version which protects the sidewalls and delivers additional cornering bite. Our new CONTROL casing has a slight extension in the casing overlap to give the best prevention of pinch flats. Lastly our proprietary GRIPTON® compound gives the tire a livelier feel and more grip in either wet or dry conditions. Specialized Fast Trak CONTROL 2Bliss Ready Bicycle Tire in Black
